Mountain gun
–
Mountain guns are artillery pieces designed for use in mountain warfare and areas where usual wheeled transport is not possible. They are similar to infantry support guns, and are capable of being broken down into smaller loads. Due to their ability to be broken down into smaller packages, during the American Civil War these small portable guns were widely used and were called mountain howitzers. Mountain guns are largely outdated, their role being filled by mortars, multiple rocket launchers, recoilless rifles, most modern artillery is manufactured from light-weight materials and can be transported fully assembled by helicopters

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

Nepal
–
Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked central Himalayan country in South Asia. Nepal is divided into 7 provinces and 75 districts and 744 local units including 4 metropolises,13 sub-metropolises,246 municipal councils and 481 village and it has a population of 26.4 million and is the 93rd largest country by area. Bordering China in the north and India in the south, east, Nepal does not border Bangladesh, which is located within only 27 km of its southeastern tip. It neither borders Bhutan due to the Indian state of Sikkim being located in between, Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the worlds ten tallest mountains, including Mount Everest, the highest point on Earth. Kathmandu is the capital and largest city. It is a nation with Nepali as the official language. The territory of Nepal has a history since the Neolithic age. The name Nepal is first recorded in texts from the Vedic Age, the era which founded Hinduism, in the middle of the first millennium BCE, Gautama Buddha, the founder of Buddhism, was born in southern Nepal. Parts of northern Nepal were intertwined with the culture of Tibet, the Kathmandu Valley in central Nepal became known as Nepal proper because of its complex urban civilization. It was the seat of the prosperous Newar confederacy known as Nepal Mandala, the Himalayan branch of the ancient Silk Road was dominated by the valleys traders. The cosmopolitan region developed distinct traditional art and architecture, by the 18th century, the Gorkha Kingdom achieved the unification of Nepal. The Shah dynasty established the Kingdom of Nepal and later formed an alliance with the British Empire, the country was never colonized but served as a buffer state between Imperial China and Colonial India. In the 20th century, Nepal ended its isolation and forged ties with regional powers. Parliamentary democracy was introduced in 1951, but was suspended by Nepalese monarchs in 1960 and 2005. The Nepalese Civil War resulted in the proclamation of a republic in 2008, modern Nepal is a federal secular parliamentary republic. Nepal is a nation, ranking 144th on the Human Development Index in 2016. The country struggles with the transition from a monarchy to a republic and it also suffers from high levels of hunger and poverty. Despite these challenges, Nepal is making progress, with the government declaring its commitment to elevate the nation from least developed country status by 2022

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Indo-Pakistani War of 1965
–
The Indo-Pakistani War of 1965 was a culmination of skirmishes that took place between April 1965 and September 1965 between Pakistan and India. The conflict began following Pakistans Operation Gibraltar, which was designed to infiltrate forces into Jammu, India retaliated by launching a full-scale military attack on West Pakistan. The seventeen-day war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II, much of the war was fought by the countries land forces in Kashmir and along the border between India and Pakistan. Most of the battles were fought by opposing infantry and armoured units, with backing from air forces. In spite of shortcomings, the Pakistan Army managed to fight the larger Indian Army. Many details of war, like those of other Indo-Pakistani Wars. Despite the cease-fire rendering the conflict militarily inconclusive, both India and Pakistan claimed victory, most neutral assessments, however, agree that India had the upper hand over Pakistan when the ceasefire was declared. Internationally, the war was viewed in the context of the greater Cold War, before the war, the United States and the United Kingdom had been major material allies of both India and Pakistan, as their primary suppliers of military hardware and foreign developmental aid. As a consequence, India and Pakistan openly developed closer relationships with the Soviet Union and China, the perceived negative stance of the western powers during the conflict, and during the 1971 war, has continued to affect relations between the West and the subcontinent. Since the Partition of British India in 1947, Pakistan and India remained in contention over several issues. Although the Kashmir conflict was the predominant issue dividing the nations, other border disputes existed, most notably over the Rann of Kutch, the issue first arose in 1956 which ended with India regaining control over the disputed area. Pakistani patrols began patrolling in territory controlled by India in January 1965, initially involving border police from both nations, the disputed area soon witnessed intermittent skirmishes between the countries armed forces. In June 1965, British Prime Minister Harold Wilson successfully persuaded both countries to end hostilities and set up a tribunal to resolve the dispute. The verdict, which later in 1968, saw Pakistan awarded 350 square miles of the Rann of Kutch. Pakistan believed that the population of Kashmir was generally discontented with Indian rule, Pakistan attempted to ignite the resistance movement by means of a covert infiltration, codenamed Operation Gibraltar. The Pakistani infiltrators were discovered, however, their presence reported by local Kashmiris. On 5 August 1965 between 26,000 and 33,000 Pakistani soldiers crossed the Line of Control dressed as Kashmiri locals headed for various areas within Kashmir, Indian forces, tipped off by the local populace, crossed the cease fire line on 15 August. Initially, the Indian Army met with success, capturing three important mountain positions after a prolonged artillery barrage

Gun barrel
–
A gun barrel is a part of firearms and artillery pieces. The hollow interior of the barrel is called the bore, a gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out by the expanding gas. Modern small arms barrels are made of known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength, early firearms were muzzle-loading, with powder, and then shot loaded from the muzzle, capable of only a low rate of fire. During the 19th century effective mechanical locks were invented that sealed a breech-loading weapon against the escape of propellant gases, the early Chinese, the inventors of gunpowder, used bamboo, a naturally tubular stalk, as the first barrels in gunpowder projectile weapons. Early European guns were made of iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings. The Chinese were the first to master cast-iron cannon barrels, early cannon barrels were very thick for their caliber.

Shell (projectile)
–
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used, originally, it was called a bombshell, but shell has come to be unambiguous in a military context. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages, shells are usually large-calibre projectiles fired by artillery, combat vehicles, and warships. Shells usually have the shape of a cylinder topped by a nose for good aerodynamic performance, possibly with a tapering base. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism hit the target. Therefore, shells needed a fuse that was ignited before or during firing. The earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376, shells with fuses were used at the 1421 siege of St Boniface in Corsica. These were two hollowed hemispheres of stone or bronze held together by an iron hoop, as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th Century grenades made of ceramics or glass were in use in Central Europe, a hoard of several hundred ceramic greandes were discovered during building works in front of a bastion of the Bavarian City of Ingolstadt, Germany dated to the 17th Century. Lots of the grenades obtained their orignal blackpowder loads and igniters, most probably the grenades were intentionally dumped the moat of the bastion before the year 1723. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse, other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Nevertheless, shells came into use in the 16th Century. By the 18th Century, it was known that the fuse towards the muzzle could be lit by the flash through the windage between the shell and the barrel, the use of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder and they were usually made of cast iron, but bronze, lead, brass and even glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, typically, the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same calibre. To ensure that shells were loaded with their fuses towards the muzzle, in 1819, a committee of British artillery officers recognised that they were essential stores and in 1830 Britain standardised sabot thickness as a half inch. The sabot was also intended to reduce jamming during loading, despite the use of exploding shell, the use of smoothbore cannons, firing spherical projectiles of shot, remained the dominant artillery method until the 1850s. By the late 18th century, artillery could use canister shot to defend itself from infantry or cavalry attack and this involved loading a tin or canvas container filled with small iron or lead balls instead of the usual cannonball

Glossary of British ordnance terms
–
This article explains terms used for the British Armed Forces ordnance and also ammunition. The terms may have different meanings in the military of other countries. Between decks, applies to a gun mounting in which part of the rotating mass is below the deck. This allows for a profile of turret, meaning that turrets need not be superfiring The term BL, in its general sense, stood for breech loading. The shell was loaded via the breech followed by the propellant charge, sealing the chamber to prevent escape of the propellant gases. The term BL was first used to refer to the Armstrong breechloaders, following the discontinuation of Armstrong breechloaders and the period of British rifled muzzle-loaders, British breechloaders were re-introduced in 1880. Early British Elswick breechloaders in the 1880s used a steel cup obturation method and this was quickly superseded in guns designed by the Royal Gun Factory by the French de Bange method, the basic principle of which is still in use today. In British service this became a Crossley pad with an interrupted thread screw block e. g. a Welin screw, the shell was loaded via the breech, followed by the propellant charge in a cloth bag. A single-use vent sealing tube, a type of primer not dissimilar in appearance to a rifle round, was inserted into the breech for firing the gun. For instance, Britain before World War I had both QF and BL6 inch guns and this presented difficulties for BL guns at high angles. A special cartridge was developed for BL9.2 inch guns on H. A. mountings, using multiple small fabric bags also allows the gunners to use a reduced charge if need be. The term BLC stood for BL converted and referred to a breech and breech mechanism modified from an early long-screw three- or four-motion to modern short-screw single-motion, an example is the conversion of the BL15 pounder to BLC15 pounder. Calibre radius head, the radius of a circle with the curve of the nose on its circumference. The longer and more pointed the nose, the higher the C. R. H. Typical C. R. H. for British shells leading up to World War I was two, e. g. the curve of the nose of a two C. R. H. Six-inch shell was equivalent to the curve of a circle with a radius of 12 inches, shells of four C. R. H. were soon developed in World War I, identified by an A following the shell mark number, B for six and so on. For modern streamlined shells post-World War I, two numbers were necessary to more correctly denote a shells C. R. H, for instance, the World War I6 inch 26 cwt howitzer shell was two C. R. H. The World War II Mk 2D shell was correctly described as 5/10 C. R. H, in this use it is synonymous with round

Shrapnel shell
–
They relied almost entirely on the shells velocity for their lethality. The munition has been obsolete since the end of World War I for anti-personnel use, the functioning and principles behind Shrapnel shells are fundamentally different from high-explosive shell fragmentation. In 1784, Lieutenant Shrapnel of the Royal Artillery began developing an anti-personnel weapon, when fired, the container burst open during passage through the bore or at the muzzle, giving the effect of an oversized shotgun shell. At ranges of up to 300 m canister shot was still highly lethal, though at this range the shots’ density was much lower and his shell was a hollow cast-iron sphere filled with a mixture of balls and powder, with a crude time fuze. If the fuze was set correctly then the shell would break open, either in front or above the intended target, the shrapnel balls would carry on with the remaining velocity of the shell. The explosive charge in the shell was to be just enough to break the casing rather than scatter the shot in all directions, as such his invention increased the effective range of canister shot from 300 to about 1100 m. He called his device spherical case shot, but in time it came to be called after him, Various solutions were tried, with limited if any success. However, in 1852 Colonel Boxer proposed using a diaphragm to separate the bullets from the bursting charge, as a buffer to prevent lead shot deforming, a resin was used as a packing material between the shot. A useful side effect of using the resin was that the combustion also gave a visual reference upon the shell bursting and it took until 1803 for the British artillery to adopt the shrapnel shell, albeit with great enthusiasm when it did. Henry Shrapnel was promoted to major in the same year, the first recorded use of shrapnel by the British was in 1804 against the Dutch at Fort Nieuw-Amsterdam in Surinam. The Duke of Wellingtons armies used it from 1808 in the Peninsular War and at the Battle of Waterloo, the design was improved by Captain E. M. Boxer of the Royal Arsenal around 1852 and crossed over when cylindrical shells for rifled guns were introduced. The powder charge both shattered the cast iron wall and liberated the bullets. The broken shell wall continued mainly forward but had little destructive effect, in the 1870s William Armstrong provided a design with the bursting charge in the head and the shell wall made of steel and hence much thinner than previous cast-iron shrapnel shell walls. Britain adopted this solution for several smaller calibres but by World War I few if any such shells remained, the final shrapnel shell design, adopted in the 1880s, bore little similarity to Henry Shrapnels original design other than its spherical bullets and time fuze. It used a much thinner forged steel shell case with a fuze in the nose. The use of steel allowed the wall to be made much thinner. It also withstood the force of the charge without shattering, so that the bullets were fired forward out of the shell case with increased velocity. This is the design came to be adopted by all countries and was in standard use when World War I began in 1914

High-explosive anti-tank warhead
–
High-explosive anti-tank warhead is a type of shaped charge explosive that uses the Munroe effect to penetrate armor. The warhead functions by having the explosive charge melt a metal liner to form a high-velocity superplastic jet and this concentrated metal jet is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge. Contrary to a misconception, the jet does not melt its way through armor. The HEAT warhead has become less effective against tanks and other armored vehicles due to the use of composite armour, HEAT warheads were developed during World War II, from extensive research and development into shaped charge warheads. Shaped charge warheads were promoted internationally by the Swiss inventor Henry Mohaupt, before 1939, Mohaupt demonstrated his invention to British and French ordnance authorities. Claims for priority of invention are difficult to due to subsequent historic interpretations, secrecy, espionage. This has some claim to have been the first HEAT warhead, the design of the warhead was simple and was capable of penetrating 52 millimetres of armour. The fuze of the grenade was armed by removing a pin in the tail which prevented the firing pin from flying forward. Simple fins gave it stability in the air and, provided the hit the target at the proper angle of 90 degrees. Detonation occurred on impact, when a striker in the tail of the grenade overcame the resistance of a spring and was thrown forward into a stab detonator. By mid-1940, Germany introduced the first HEAT round to be fired by a gun, the 7.5 centimetres fired by the Kw. K.37 L/24 of the Panzer IV tank and the Stug III self-propelled gun. The Panzerfaust and Panzerschreck gave the German infantryman the ability to any tank on the battlefield from 50–150 metres with relative ease of use. The Germans made use of quantities of HEAT ammunition in converted 7.5 cm Pak 97/38 guns from 1942. These so-called Schwere Hohlladung warheads were intended for use against heavily armoured battleships, operational versions weighed nearly two tons and were perhaps the largest HEAT warheads ever deployed. A five-ton version code-named Beethoven was also developed, meanwhile, the British No.68 AT rifle grenade was proving to be too light to deal significant damage, resulting in it rarely being used in action. Due to these limits, a new infantry weapon was needed. By 1942, the PIAT had been developed by Major Millis Jefferis and it was a combination of a HEAT warhead with a spigot mortar delivery system. While cumbersome, the weapon allowed British infantry to armour at range for the first time
12.
Caliber
–
In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch. For example, a 45 caliber firearm has a diameter of.45 of an inch. Barrel diameters can also be expressed using metric dimensions, as in 9mm pistol, when the barrel diameter is given in inches, the abbreviation cal can be used. Good performance requires a bullet to closely match the diameter of a barrel to ensure a good seal. While modern cartridges and cartridge firearms are referred to by the cartridge name. Firearm calibers outside the range of 17 to 50 exist, but are rarely encountered. Larger calibers, such as.577.585.600.700, the.950 JDJ is the only known cartridge beyond 79 caliber used in a rifle. Referring to artillery, caliber is used to describe the length as multiples of the bore diameter. A 5-inch 50 calibre gun has a diameter of 5 in. The main guns of the USS Missouri are 1650 caliber, makers of early cartridge arms had to invent methods of naming the cartridges, since no established convention existed then. One of the early established cartridge arms was the Spencer repeating rifle, later various derivatives were created using the same basic cartridge, but with smaller-diameter bullets, these were named by the cartridge diameter at the base and mouth. The original No.56 became the. 56-56, and the smaller versions. 56-52. 56-50, the. 56-52, the most common of the new calibers, used a 50-cal bullet. Optionally, the weight in grains was designated, e. g. 45-70-405. Variations on these methods persist today, with new cartridges such as the.204 Ruger, metric diameters for small arms refer to cartridge dimensions and are expressed with an × between the bore diameter and the length of the cartridge case, for example,7. 62×51 NATO. This indicates that the diameter is 7. 62mm, loaded in a case 51mm long. Similarly, the 6. 5×55 Swedish cartridge has a diameter of 6.5 mm. An exception to rule is the proprietary cartridge used by U. S. maker Lazzeroni. The following table lists commonly used calibers where both metric and imperial are used as equivalents
13.
Recoil
–
Recoil is the backward movement of a gun when it is discharged. To apply this counter-recoiling force, modern mounted guns may employ recoil buffering comprising springs and hydraulic recoil mechanisms, early cannons used systems of ropes along with rolling or sliding friction to provide forces to slow the recoiling cannon to a stop. Recoil buffering allows the maximum counter-recoil force to be lowered so that strength limitations of the gun mount are not exceeded, however, the same pressures acting on the base of the projectile are acting on the rear face of the gun chamber, accelerating the gun rearward during firing. This results in the required counter-recoiling force being proportionally lower, modern cannons also employ muzzle brakes very effectively to redirect some of the propellant gasses rearward after projectile exit. This provides a force to the barrel, allowing the buffering system. The same physics affecting recoil in mounted guns and cannons applies to hand-held guns, hands, arms and shoulders have considerable strength and elasticity for this purpose, up to certain practical limits. For this reason, establishing recoil safety standards for small arms remains challenging, a change in momentum of a mass requires a force, according to Newtons first law, known as the law of inertia, inertia simply being another term for mass. That force, applied to a mass, creates an acceleration, according to Newtons second law, the law of momentum -- changing the velocity of the mass changes its momentum. It is important to understand at this point that velocity is not simply speed, velocity is the speed of a mass in a particular direction. In a very technical sense, speed is a scalar, a magnitude, in summation, the total momentum of the system equals zero, surprisingly just as it did before the trigger was pulled. There are two conservation laws at work when a gun is fired, conservation of momentum and conservation of energy, recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy. The nature of the process is determined by the force of the expanding gases in the barrel upon the gun. It is also determined by the force applied to the gun. The recoil force only acts during the time that the ejecta are still in the barrel of the gun, except for the case of zero-recoil, the counter-recoil force is smaller than the recoil force but lasts for a longer time. Since the recoil force and the force are not matched. In the zero-recoil case, the two forces are matched and the gun will not move when fired. In most cases, a gun is very close to a free-recoil condition, an example of near zero-recoil would be a gun securely clamped to a massive or well-anchored table, or supported from behind by a massive wall. For example, placing the butt of a large caliber gun directly against a wall, the recoil of a firearm, whether large or small, is a result of the law of conservation of momentum
14.
Gun carriage
–
A gun carriage is a frame and mount that supports the gun barrel of an artillery piece, allowing it to be manoeuvred and fired. The earliest guns were laid directly onto the ground, with earth being piled up under the end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century, from the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion had been developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iron band. This simplified elevation, which was achieved by raising or lowering the breech of the gun by means of a wedge called a quoin or later by a steel screw. During this time, the design of gun carriages evolved only slowly, the trunnions of the gun barrel sat on the top of the cheeks, the rearward part of each cheek was stepped so that the breech could be lifted by iron levers called handspikes. Traversing the gun was achieved by levering the rear of the carriage sideways with handspikes and these were designed to allow guns to be deployed on the battlefield and were provided with a pair of large wheels similar to those used on carts or wagons. The cheeks of field carriages were much narrower than those on the naval carriage, when the gun needed to be moved any distance, the trail could be lifted onto a second separate axle called a limber, which could then be towed by a team of horses or oxen. Limbers had been invented in France in about 1550, in recent times, most heavy guns in military service, that were not themselves mounted into a vehicles, have been mounted either with a field carriage or a split trail carriage. The field carriage is simpler - having two legs extend backwards, joining at a tail, being a hardpoint to hook on to a prime mover or set of horses, the split trail carriage, however, is more complicated, but offers distinct advantages. It consists of two legs, able to be spread independently to the sides, or brought together to allow towing or movement, in both cases, the tail of the carriage often serves to balance the gun, and protect it from rolling to any large extent. The split trail, however, allows the gun not only to be fired near the horizontal, as the field carriage does and this is less important for heavier artillery, as the guns already involve a long time to prepare a firing position. While this still limits the ability to track, it allows the guns to fire in any direction with minimal preparation. Furthermore, it part of each of the benefits of the field carriage, being weight, space. The practice has its origins in war and appears in the century in the Queens regulations of the British Army. In the United Kingdom, the visual distinction usually referred to is that in a state funeral and this distinguishing feature is not invariable, however, as shown by the use of naval ratings rather than horses at the ceremonial funeral for Lord Mountbatten in 1979

Gun laying
–
Gun laying is the process of aiming an artillery piece, such as a gun, howitzer or mortar on land, or at sea, against surface or air targets. It may be laying for direct fire, where the gun is aimed similarly to a rifle, or indirect fire, the term includes automated aiming using, for example, radar-derived target data and computer-controlled guns. Gun laying means moving the axis of the bore of the barrel in two planes, horizontal and vertical. A gun is traversed – rotated in a horizontal plane – to align it with the target, Gun laying is a set of actions to align the axis of a gun barrel so that it points in the required direction. This alignment is in the horizontal and vertical planes, Gun laying may be for direct fire, where the layer sees the target, or indirect fire, where the target may not be visible from the gun. Gun laying has sometimes called training the gun. Laying in the vertical plane uses data derived from trials or empirical experience, for any given gun and projectile types, it reflects the distance to the target and the size of the propellant charge. It also incorporates any differences in height between gun and target, with indirect fire, it may allow for other variables as well. With indirect fire the horizontal angle is relative to something, typically the guns aiming point, depending on the gun mount, there is usually a choice of two trajectories. The dividing angle between the trajectories is about 45 degrees, it varies due to gun dependent factors. Below 45 degrees the trajectory is called low angle, above is high angle, the differences are that low angle fire has a shorter time of flight, a lower vertex and flatter angle of descent. All guns have carriages or mountings that support the barrel assembly, early guns could only be traversed by moving their entire carriage or mounting, and this lasted with heavy artillery into World War II. Mountings could be fitted into traversing turrets on ships, coast defences or tanks, from circa 1900 field artillery carriages provided traverse without moving the wheels and trail. The carriage, or mounting, also enabled the barrel to be set at the elevation angle. With some gun mounts it is possible to depress the gun, some guns require a near-horizontal elevation for loading. An essential capability for any elevation mechanism is to prevent the weight of the barrel forcing its heavier end downward and this is greatly helped by having trunnions at the centre of gravity, although a counterbalance mechanism can be used. It also means the elevation gear has to be enough to resist considerable downward pressure. However, mortars, where the forces were transferred directly into the ground

Commonwealth of Nations
–
The Commonwealth of Nations, also known as simply the Commonwealth, is an intergovernmental organisation of 52 member states that are mostly former territories of the British Empire. The Commonwealth dates back to the century with the decolonisation of the British Empire through increased self-governance of its territories. It was formally constituted by the London Declaration in 1949, which established the states as free. The symbol of free association is Queen Elizabeth II who is the Head of the Commonwealth. The Queen is also the monarch of 16 members of the Commonwealth, the other Commonwealth members have different heads of state,31 members are republics and five are monarchies with a different monarch. Member states have no obligation to one another. Instead, they are united by language, history, culture and their values of democracy, free speech, human rights. These values are enshrined in the Commonwealth Charter and promoted by the quadrennial Commonwealth Games, the Commonwealth covers more than 29,958,050 km2, 20% of the worlds land area, and spans all six inhabited continents. She declared, So, it marks the beginning of that free association of independent states which is now known as the Commonwealth of Nations. As long ago as 1884, however, Lord Rosebery, while visiting Australia, had described the changing British Empire—as some of its colonies became more independent—as a Commonwealth of Nations. Conferences of British and colonial prime ministers occurred periodically from the first one in 1887, the Commonwealth developed from the imperial conferences. Newfoundland never did, as on 16 February 1934, with the consent of its parliament, Newfoundland later joined Canada as its 10th province in 1949. Australia and New Zealand ratified the Statute in 1942 and 1947 respectively, after World War II ended, the British Empire was gradually dismantled. Most of its components have become independent countries, whether Commonwealth realms or republics, there remain the 14 British overseas territories still held by the United Kingdom. In April 1949, following the London Declaration, the word British was dropped from the title of the Commonwealth to reflect its changing nature, burma and Aden are the only states that were British colonies at the time of the war not to have joined the Commonwealth upon independence. Hoped for success was reinforced by such achievements as climbing Mount Everest in 1953, breaking the four minute mile in 1954, however, the humiliation of the Suez Crisis of 1956 badly hurt morale of Britain and the Commonwealth as a whole. More broadly, there was the loss of a role of the British Empire. That role was no longer militarily or financially feasible, as Britains withdrawal from Greece in 1947 painfully demonstrated, Britain itself was now just one part of the NATO military alliance in which the Commonwealth had no role apart from Canada

British Indian Army
–
The Indian Army was the principal army of India before independence from the United Kingdom in 1947. It was responsible for the defence of both British India and the Princely states, which could also have their own armies. The Indian Army was an important part of the British Empires forces, the term Indian Army appears to have been first used informally, as a collective description of the Presidency armies of the Presidencies of British India, particularly after the Indian Rebellion. The first army officially called the Indian Army was raised by the government of India in 1895, however, in 1903 the Indian Army absorbed these three armies. The Indian Army should not be confused with the Army of India which was the Indian Army itself plus the British Army in India, before 1858, the precursor units of the Indian Army were units controlled by the Company and were paid for by their profits. These operated alongside units of the British Army, funded by the British government in London. Many of these took part in the Indian Mutiny, with the aim of reinstating the Mughal Emperor Bahadur Shah II at Delhi. The meaning of the term Indian Army has changed over time, The officer commanding the Army of India was the Commander-in-Chief, the title was used before the creation of a unified British Indian Army, the first holder was Major General Stringer Lawrence in 1748. By the early 1900s the Commander-in-Chief and his staff were based at GHQ India, Indian Army postings were less prestigious than British Army positions, but the pay was significantly greater so that officers could live on their salaries instead of having to have a private income. Accordingly, vacancies in the Indian Army were much sought after and generally reserved for the higher placed officer-cadets graduating from the Royal Military College, Sandhurst. British officers in the Indian Army were expected to learn to speak the Indian languages of their men, prominent British Indian Army officers included Frederick Roberts, 1st Earl Roberts, William Birdwood, 1st Baron Birdwood, Claude Auchinleck and William Slim, 1st Viscount Slim. Commissioned officers, British and Indian, held identical ranks to commissioned officers of the British Army, Kings Commissioned Indian Officers, created from the 1920s, held equal powers to British officers. Viceroys Commissioned Officers were Indians holding officer ranks and they were treated in almost all respects as commissioned officers, but had authority over Indian troops only, and were subordinate to all British Kings Commissioned Officers and KCIOs. They included Subedar Major or Risaldar-Major, equivalents to a British Major, Subedar or Risaldar equivalents to Captain, recruitment was entirely voluntary, about 1.75 million men served in the First World War, many on the Western Front and 2.5 million in the Second. Soldier ranks included Sepoys or Sowars, equivalent to a British private, British Army ranks such as gunner and sapper were used by other corps. In the aftermath of the Indian Mutiny of 1857, also known as the Sepoy Mutiny. The three Presidency armies remained separate forces, each with its own Commander-in-Chief, overall operational control was exercised by the Commander-in-Chief of the Bengal Army, who was formally the Commander-in-Chief of the East Indies. From 1861, most of the manpower was pooled in the three Presidential Staff Corps

BL 10-pounder mountain gun
–
The Ordnance BL10 pounder mountain gun was developed as a BL successor to the RML2.5 inch screw gun which was outclassed in the Second Boer War. This breech-loading gun was an improvement on the 2.5 inches muzzle-loading screw gun and it could be dismantled into 4 loads of approximately 200 pounds for transport, typically by mule. It was eventually replaced by the BL2.75 inch Mountain Gun from 1914 onwards but was still the main gun in service when World War I began. British mountain guns were operated by men of the Royal Garrison Artillery, the 21st Battery was granted the title Royal in 1922 for its actions including Gallipoli, unique for an artillery battery. 28th Mountain Battery with 6 guns arrived with Indian Expeditionary Force B from 30 October 1914, returned to India December 1916. 28th Batterys first engagement occurred with the guns tied to the deck of HM Transport ship Bharata, 1st Kashmir arrived 5 December 1916, returned to India 2 February 1918. Between them the 1st and 27th were awarded 2 Order Of British India,1 Indian Distinguished Service Medal,7 Meritorious Service Medals,12 Mentioned in Despatches. 24th Hazara Mountain Battery served in East Africa from 26 April 1917, a typical extract from their War Diary reads, Ndundwala 2nd July 1917. One section came into action and fired 87 rounds shrapnel at enemy holding river crossing place at range 750 yards, forward observer reported three direct hits on his breastworks. Sniping continued 19 August 1917, constructed an emplacement within 150 yards of enemy, tubes which were dated 1901 are very bad and several misfires occurred. During last 15 days fired 548 shrapnel,35 common and 4 star shells at average range of 1,000 yards and they returned to India in November 1918. 22nd Mountain Battery arrived in the East Africa campaign on 18 December 1916 and they returned to India in November 1918. The gun was used in the Palestine campaign. Osprey Publishing, Oxford UK,2004 ISBN 1-84176-688-7 General Sir Martin Farndale, the Forgotten Fronts and the Home Base, 1914-18.

Second Boer War
–
The Second Boer War, usually known as the Boer War and also at the time as the South African War, started on 11 October 1899 and ended on 31 May 1902. Great Britain defeated two Boer states in South Africa, the South African Republic and the Orange Free State, Britain was aided by its Cape Colony, Colony of Natal and some native African allies. The British war effort was supported by volunteers from the British Empire, including Southern Africa, the Australian colonies, Canada, India. All other nations were neutral, but public opinion in them was largely hostile to Britain, inside Britain and its Empire there also was significant opposition to the Second Boer War. The British were overconfident and under-prepared, the Boers were very well armed and struck first, besieging Ladysmith, Kimberley, and Mafeking in early 1900, and winning important battles at Colenso, Magersfontein and Stormberg. Staggered, the British brought in numbers of soldiers and fought back. General Redvers Buller was replaced by Lord Roberts and Lord Kitchener and they relieved the three besieged cities, and invaded the two Boer republics in late 1900. The onward marches of the British Army were so overwhelming that the Boers did not fight staged battles in defense of their homeland, the British quickly seized control of all of the Orange Free State and Transvaal, as the civilian leadership went into hiding or exile. In conventional terms, the war was over, Britain officially annexed the two countries in 1900, and called a khaki election to give the government another six years of power in London. However, the Boers refused to surrender and they reverted to guerrilla warfare under new generals Louis Botha, Jan Smuts, Christiaan de Wet and Koos de la Rey. Two more years of attacks and quick escapes followed. As guerrillas without uniforms, the Boer fighters easily blended into the farmlands, which provided hiding places, supplies, the British solution was to set up complex nets of block houses, strong points, and barbed wire fences, partitioning off the entire conquered territory. The civilian farmers were relocated into concentration camps, where very large proportions died of disease, especially the children, then the British mounted infantry units systematically tracked down the highly mobile Boer guerrilla units. The battles at this stage were small operations with few combat casualties The war ended in surrender, the British successfully won over the Boer leaders, who now gave full support to the new political system. Both former republics were incorporated into the Union of South Africa in 1910, the conflict is commonly referred to as simply the Boer War, since the First Boer War is much less well known. Boer was the term for Afrikaans-speaking white South Africans descended from the Dutch East India Companys original settlers at the Cape of Good Hope. It is officially called the South African War and it is known as the Anglo-Boer War among some South Africans. In Afrikaans it may be called the Anglo-Boereoorlog, Tweede Boereoorlog, in South Africa it is officially called the South African War

BL 2.75-inch mountain gun
–
The Ordnance BL2. 75-inch mountain gun was a screw gun designed for and used by the Indian Mountain Artillery into World War I. The gun was a version of the 1901 BL 10-pounder mountain gun. The new 1911 version improved on the 1901 gun with a new trail, recoil buffer, recuperator and gunshield. It was a gun design, where the barrel could be separated into two parts via a screw joint. This allowed for the gun to have a barrel. This was important for a designed to be used in mountainous and rough terrain, or where adequate vehicle. The weapon could be carried by six mules or towed, the gun was adopted in 1911 and began entering service in 1914. The weapon served primarily with the Indian Mountain Artillery in the northwest portion of British Indian territory and it also served in Mesopotamia and the Salonika front during World War I. Due to its nature the gun was produced in only limited numbers. It was superseded at the end of World War I by the QF3. 7-inch mountain howitzer, a 2. 75-inch mountain gun is on display at the Heugh Battery Museum, Hartlepool List of mountain artillery Dale Clarke, British Artillery 1914-1919.

Mesopotamian campaign
–
The Ottoman Empire had conquered the region in the early 16th century, but never fully gained complete control. Regional pockets of Ottoman control through local rulers maintained the Ottomans reach throughout Mesopotamia. With the turn of the 19th century came reforms, work began on a Baghdad Railway in 1888, by 1915 it had only four gaps, and travel time from Istanbul to Baghdad had fallen to 21 days. The Anglo-Persian Oil Company had obtained rights to petroleum deposits throughout the Persian Empire, except in the provinces of Azerbaijan, Ghilan, Mazendaran, Asdrabad. In 1914, before the war, the British government had contracted with the company for oil for the navy, the operational area of the Mesopotamian campaign was limited to the lands watered by the rivers Euphrates and Tigris. The main challenge was moving troops and supplies through the swamps, shortly after the European war started, the British sent a military force to protect Abadan, the site of one of the worlds earliest oil refineries. British operational planning included landing troops in the Shatt-al-Arab, the reinforced 6th Division of the British Indian Army was assigned the task, designated as Indian Expeditionary Force D. At first the campaign was run by the India Office and Indian Army, the Ottoman Fourth Army was located in the region. It was composed of two corps, the XII Corps, with the 35th and 36th Divisions at Mosul, and XIII Corps, on 29 October 1914, after the pursuit of Goeben and Breslau, Breslau bombarded the Russian Black Sea port of Theodosia. On 30 October the High Command in Istanbul changed the force distribution, on 2 November Grand Vizier Said Halim Pasha expressed regret to the Allies for the actions of the navy. Russian Minister of Foreign Affairs Sergey Sazonov said it was too late, the Cabinet tried to explain that hostilities were begun without its sanction by German officers serving in the navy. The Ottoman Committee of Union and Progresss official Declaration of War came on 14 November, when the Caucasus Campaign became a reality with the Bergmann Offensive, Enver Pasha sent the 37th Division and XIII Corps Headquarters to the Caucasus in support of the Third Army. The entire XII Corps was deployed to the Sinai and Palestine Campaign, Fourth Army Headquarters was sent to Syria, to replace the Second Army Headquarters, which was sent to Istanbul. In place of the Fourth Army was the Iraq Area Command with only the 38th Division under its command, Mesopotamia was a low priority area for the Ottomans, and they did not expect any major action in the region. Regiments of the XII and XIII Corps were maintained at low levels in peacetime, lieutenant Colonel Süleyman Askerî Bey became the commander. He redeployed portions of the 38th Division at the mouth of Shatt-al-Arab, the rest of the defensive force was stationed at Basra. The Ottoman General Staff did not even possess a proper map of Mesopotamia and they tried to draw a map with the help of people who had worked in Iraq before the war, although this attempt failed. Enver Pasha bought two German maps scaled 1/1,500,000, on 6 November 1914, British offensive action began with the naval bombardment of the old fort at Fao, located at the point where the Shatt-al-Arab meets the Persian Gulf

East African Campaign (World War I)
–
The campaign all but ended in November 1917, when the Germans entered Portuguese East Africa and continued the campaign living off Portuguese supplies. The strategy of the German colonial forces, led by Lieutenant Colonel Paul Emil von Lettow-Vorbeck, was to divert forces from the Western Front to Africa. His strategy achieved only mixed results after 1916, when he was out of German East Africa and Allied forces became composed almost entirely of South African, Indian. The Germans fought for the whole of World War I, receiving word of the armistice on 14 November 1918 at 7,30 a. m, both sides waited for confirmation and the Germans formally surrendered on 25 November. German East Africa became two League of Nations Class B Mandates, Tanganyika Territory of the United Kingdom and Ruanda-Urundi of Belgium, German East Africa was colonized by the Germans in 1885. The territory itself spanned 384,180 square miles and covered the areas of modern-day Rwanda, Burundi, the colonys indigenous population numbered seven and a half million and was governed by just 5,300 Europeans. Although the colonial regime was relatively secure, the colony had recently been shaken by the Maji Maji Rebellion of 1904–05 whose effects were still being felt by 1914. The outbreak of World War I in Europe led to the popularity of German colonial expansion. Mittelafrika effectively involved the annexation of territory, mostly occupied by the Belgian Congo, the territory would dominate central Africa and would make Germany as by far the most powerful colonial power on the African continent. Nevertheless, the German colonial military in Africa was weak, poorly equipped, although better trained and more experienced than their opponents, many of the German soldiers were reliant on weapons like the Model 1871 rifle which used obsolete black powder. Even the largest concentration of German troops in the continent in East Africa, was unable to fight an aggressive war. By threatening the important British Uganda Railway, von Lettow hoped to force British troops to invade East Africa, in 1912, the German government had formed a defence strategy for East Africa in which the military would withdraw from the coast into the hinterland and fight a guerrilla campaign. For the Belgians, the German presence in East Africa was a threat to the security of Congo, the Colonial Minister, Jules Renkin, favoured a policy of trading territory gained in East Africa with the Portuguese, to expand the western Congo coast in a post-war settlement. A successful campaign in Africa was also seen as a way for the De Broqueville government to avenge the German invasion of Belgium, in East Africa, the Congo Act was first broken by the British. On 15 August, German Askari forces stationed in the Neu Moshi region engaged in their first offensive of the campaign, taveta on the British side of Kilimanjaro fell to 300 Askari of two field companies with the British firing a token volley and retiring in good order. In September, the Germans began to stage raids deeper into British East Africa, German naval power on Lake Victoria was limited to Hedwig von Wissmann and Kingani a tugboat armed with one pom-pom gun, causing minor damage but a great deal of news. The British then armed the Uganda Railway lake steamers SS William Mackinnon, SS Kavirondo, Winifred, the tug was trapped and then scuttled by the Germans. In an effort to solve the raiding nuisance and to capture the northern, white settler region of the German colony

Royal Artillery
–
The Royal Regiment of Artillery, commonly referred to as the Royal Artillery, is the artillery arm of the British Army. Despite its name Royal Regiment of Artillery it actually consists of 13 Regular Regiments and 5 Reserve Regiments, the introduction of artillery into the English army came as early as the Battle of Crécy in 1346. Henry VIII made the armys artillery semi-permanent in the sixteenth century, before the 18th century, artillery traynes were raised by royal warrant for specific campaigns and disbanded again when they were over. On 26 May 1716, however, by warrant of George I two regular companies of field artillery, each 100 men strong, were raised at Woolwich. The title Royal Artillery was first used in 1720, in 1741 the Royal Military Academy was formed in the Royal Arsenal at Woolwich to provide training for RA and Royal Engineers officers. The regiment expanded rapidly and, by 1757, had 24 companies divided into two battalions, as well as a company formed in 1741. During 1748, the presidential artilleries of Bengal, Madras and Bombay were formed,1756 saw the creation of the Royal Irish Regiment of Artillery. In 1762 the Royal Artillery Band was formed at Minden, by 1771 there were 32 companies in four battalions, as well as two invalid companies comprising older and unfit men employed in garrison duties. During 1782, the regiment moved to the Royal Artillery Barracks on Woolwich Common, in January 1793, two troops of Royal Horse Artillery were raised to provide fire support for the cavalry, augmented by two more in November 1793. The Royal Irish Artillery was absorbed into the RA in 1801, during 1805, the Royal Military Academy moved to Woolwich Common. In 1819, the Rotunda was given to the regiment by the Prince Regent to celebrate end of the Napoleonic Wars, in 1832, the regimental motto, Ubique Quo Fas Et Gloria Ducunt, was granted. The motto signified that the regiment had seen action in all the conflicts of the British Army. The regiment was under the control of the Board of Ordnance until the board was abolished in 1855, thereafter the regiment came under the War Office along with the rest of the army. The School of Gunnery established at Shoeburyness, Essex in 1859, the third group continued to be titled simply Royal Artillery, and was responsible for ammunition storage and supply. Which branch a gunner belonged to was indicated by metal shoulder titles, the RFA and RHA also dressed as mounted men, whereas the RGA dressed like foot soldiers. In 1920 the rank of Bombardier was instituted in the Royal Artillery, the three sections effectively functioned as separate corps. This arrangement lasted until 1924, when the three amalgamated once more to one regiment. In 1938, RA Brigades were renamed Regiments, during the World War II there were over 1 million men serving in 960 gunner regiments

Military history of the North-West Frontier
–
The North-West Frontier region of the British Indian Empire was the most difficult area to conquer in South Asia, strategically and militarily. The borderline between is known as the Durand Line and divides Pashtun inhabitants of these provinces from Pashtuns in eastern Afghanistan. The two main gateways on the North West Frontier are the Khyber and Bolan Passes, since ancient times, the Indian subcontinent has been repeatedly invaded through these northwestern routes. With the expansion of the Russian Empire into Central Asia in the century, stability of the Frontier. Much of the Frontier was occupied by Ranjit Singh in the early 19th century, between 1849 and 1947 the military history of the frontier was a succession of punitive expeditions against offending Pashtun tribes, punctuated by three wars against Afghanistan. Many British officers who went on to distinguished command in the First and Second World Wars learnt their soldiering on the North-West Frontier, which they called the Grim. In 1747 when Ahmad Khān Abdālī seized control of Kandahar, Kabul, and Peshawar and he went on to conquer Herat and Khorassan, and established an empire from the Oxus to the Indus. On his death in 1773, the Afghan domain included Baluchistan, Sindh, the Punjab, Ahmad Shah was succeeded by his son Timur Shah Durrani, whose rule of twenty years saw the Afghan tide begin to ebb. Timur left many sons but no heir, and the resultant internecine struggles for the throne lasted more than thirty years, during this period the Punjab was effectively ceded to its erstwhile governor Ranjit Singh, Iran recovered Khorassan, and Sindh broke away. In 1813 Sikh forces from the Punjab crossed the Indus and seized the old Mughal fort at Attock, in 1819 Kashmir was lost, and west of the Indus Derajat also. Four years later the capital at Peshawar came under attack. In 1826 Dost Mohammad Khan emerged as undisputed ruler in Kabul and he defeated a further attempt to oust him by his exiled rival Shuja Shah Durrani in 1833, however the Sikhs seized all of Peshawar the following year. In 1837 Dost Mohammad launched a counter-attack through the Khyber, Dost Mohammad had sought assistance from the East India Company against the resurgent Punjab, but was rebuffed. So Dost Mohammad turned to Imperial Russia for help, maharaja Ranjit Singh, also called Sher-e-Punjab was a Sikh ruler of the sovereign country of Punjab and the Sikh Empire. His Samadhi is located in Lahore, Pakistan and he then spent the following years fighting the Afghans, driving them out of western Punjab, taking opportunity of the Afghans being embroiled in civil war. The deposed Afghan king Shah Shuja rallied a significant number of tribes, the civil war in Afghanistan coupled with a British backed assault meant that the Sikhs could virtually walk into Peshawar. They managed to capture Pashtun territory including Peshawar which was under direct British supervision, at the beginning of the nineteenth century, the East India Company controlled southern India, Bengal, Bihar, and Orissa. Dominance was gained at the expense of its French equivalent, the Compagnie des Indes, by 1819 only Sindh and the Sikh Empire remained outside the Companys control

North African Campaign
–
The North African Campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts and in Morocco, the campaign was fought between the Allies and Axis powers, many of whom had colonial interests in Africa dating from the late 19th century. The Allied war effort was dominated by the British Commonwealth and exiles from German-occupied Europe, the United States entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942. Fighting in North Africa started with the Italian declaration of war on 10 June 1940, on 14 June, the British Armys 11th Hussars crossed the border from Egypt into Libya and captured the Italian Fort Capuzzo. Information gleaned via British Ultra code-breaking intelligence proved critical to Allied success in North Africa, victory for the Allies in this campaign immediately led to the Italian Campaign, which culminated in the downfall of the fascist government in Italy and the elimination of a German ally. On 10 May 1940, the Wehrmacht had started the Battle of France, one month later, it was plain to see that France would have to surrender within two weeks. On 10 June 1940, the Kingdom of Italy aligned itself with Nazi Germany and declared war upon France, British forces based in Egypt were ordered to undertake defensive measures, but to act as non-provocatively as possible. However, on 11 June they began a series of raids against Italian positions in Libya, following the defeat of France on 25 June, Italian forces in Tripolitania—facing French troops based in Tunisia—redeployed to Cyrenaica to reinforce the Italian Tenth Army. Italian dictator Benito Mussolini ordered the Tenth Army to invade Egypt by 8 August, two days later, no invasion having been launched, Mussolini ordered Marshal Graziani that, the moment German forces launched Operation Sea Lion, he was to attack. The battle plan was to advance along the road, while limited armoured forces operated on the desert flank. To counter the Italian advance, Wavell ordered his forces to harass the advancing Italians, falling back towards Mersa Matruh. Positioned on the flank was the 7th Armoured Division, which would strike the flank of the Italian force. By 16 September, the Italian force had advanced to Maktila, around 80 mi west of Mersa Matruh, in response to the dispersed Italian camps, the British planned a limited five-day attack, Operation Compass, to strike at these fortified camps one by one. The British Commonwealth force, totalling 36,000 men, attacked the forward elements of the 10-division-strong Italian army on 9 December, following their initial success, the forces of Operation Compass pursued the retreating Italian forces. In January, the port at Bardia was taken, soon followed by the seizure of the fortified port of Tobruk. Some 40,000 Italians were captured in and around the two ports, with the remainder of the Tenth Army retreating along the coast road back to El Agheila. Richard OConnor sent the 7th Armoured Division across the desert, with a reconnaissance group reaching Beda Fomm some ninety minutes before the Italians. Although desperate attempts were made to overcome the British force at the Battle of Beda Fomm, the Italians were unable to break through, and the remnants of the retreating army surrendered

Tunisia
–
Tunisia, officially the Republic of Tunisia is the northernmost country in Africa, covering 165,000 square kilometres. Its northernmost point, Cape Angela, is the northernmost point on the African continent and it is bordered by Algeria to the west and southwest, Libya to the southeast, and the Mediterranean Sea to the north and east. Tunisias population was estimated to be just under 11 million in 2014, Tunisias name is derived from its capital city, Tunis, which is located on Tunisias northeast coast. Geographically, Tunisia contains the end of the Atlas Mountains. Much of the rest of the land is fertile soil. Tunisia is a unitary semi-presidential representative democratic republic and it is considered to be the only full democracy in the Arab World. It has a human development index. In addition, Tunisia is also a state of the United Nations. Close relations with Europe – in particular with France and with Italy – have been forged through economic cooperation, privatisation, in ancient times, Tunisia was primarily inhabited by Berbers. Phoenician immigration began in the 12th century BC, these immigrants founded Carthage, a major mercantile power and a military rival of the Roman Republic, Carthage was defeated by the Romans in 146 BC. The Romans, who would occupy Tunisia for most of the eight hundred years, introduced Christianity. After several attempts starting in 647, the Arabs conquered the whole of Tunisia by 697, the Ottomans held sway for over three hundred years. The French colonization of Tunisia occurred in 1881, Tunisia gained independence with Habib Bourguiba and declared the Tunisian Republic in 1957. In 2011, the Tunisian Revolution resulted in the overthrow of President Zine El Abidine Ben Ali, the country voted for parliament again on 26 October 2014, and for President on 23 November 2014. The word Tunisia is derived from Tunis, an urban hub. The present form of the name, with its Latinate suffix -ia, the French derivative Tunisie was adopted in some European languages with slight modifications, introducing a distinctive name to designate the country. Other languages remained untouched, such as the Russian Туни́с and Spanish Túnez, in this case, the same name is used for both country and city, as with the Arabic تونس, and only by context can one tell the difference. The name Tunis can be attributed to different origins and it is generally associated with the Berber root ⵜⵏⵙ, transcribed tns, which means to lay down or encampment

Italian Campaign (World War II)
–
The Italian Campaign of World War II was the name of Allied operations in and around Italy, from 1943 to the end of the war in Europe. It is estimated that between September 1943 and April 1945, some 60, 000–70,000 Allied and 60, overall Allied casualties during the campaign totaled about 320,000 and the corresponding German figure was well over 600,000. Fascist Italy, prior to its collapse, suffered about 200,000 casualties, mostly POWs taken in the Allied invasion of Sicily, including more than 40,000 killed or missing. Besides them, over 150,000 Italian civilians died, as did 15,197 anti-Fascist partisans and 13,021 troops of the Italian Social Republic. The campaign ended when Army Group C surrendered unconditionally to the Allies on May 2,1945, the independent states of San Marino and the Vatican, both surrounded by Italian territory, also suffered damage during the campaign. Even prior to victory in the North African Campaign in May 1943, the British, especially the Prime Minister, Winston Churchill, advocated their traditional naval-based peripheral strategy. The United States, with a larger army, favoured a more direct method of fighting the main force of the German Army in Northern Europe. The ability to such a campaign depended on first winning the Battle of the Atlantic. There was even pressure from some Latin American countries to stage an invasion of Spain, the British argued that the presence of large numbers of troops trained for amphibious landings in the Mediterranean made a limited-scale invasion possible and useful. A contributing factor was Franklin D. Roosevelts desire to keep US troops active in the European theatre during 1943 and it was hoped that an invasion might knock Italy out of the conflict, or at least increase the pressure on them and weaken them further. A combined Allied invasion of Sicily began on 10 July 1943 with both amphibious and airborne landings at the Gulf of Gela, the land forces involved were the U. S. Seventh Army, under Lieutenant General George S. Patton, the original plan contemplated a strong advance by the British northwards along the east coast to Messina, with the Americans in a supporting role along their left flank. The defending German and Italian forces were unable to prevent the Allied capture of the island, but succeeded in evacuating most of their troops to the mainland, the Allied forces gained experience in opposed amphibious operations, coalition warfare and mass airborne drops. Forces of the British Eighth Army, still under Montgomery, landed in the toe of Italy on 3 September 1943 in Operation Baytown, the armistice was publicly announced on 8 September by two broadcasts, first by General Eisenhower and then by a proclamation by Marshal Badoglio. Although the German forces prepared to defend without Italian assistance, only two of their divisions opposite the Eighth Army and one at Salerno were not tied up disarming the Royal Italian Army, on 9 September, forces of the U. S. Fifth Army, under Lieutenant General Mark W, although none of the northern reserves were made available to the German 10th Army, it nevertheless came close to repelling the Salerno landing, due mainly to the cautious command of Clark. As the Allies advanced, they encountered increasingly difficult terrain, the Apennine Mountains form a spine along the Italian peninsula offset somewhat to the east, the rivers were subject to sudden and unexpected flooding, which constantly thwarted the Allied commanders plans. This would make the most of the natural geography of Central Italy, whilst denying the Allies the easy capture of a succession of airfields

Kokoda Track campaign
–
The Kokoda Track campaign or Kokoda Trail campaign was part of the Pacific War of World War II. The campaign consisted of a series of battles fought between July and November 1942 between Japanese and Allied—primarily Australian—forces in what was then the Australian territory of Papua, following a confused night battle on 28/29 July, the Australians were again forced to withdraw. The Australians attempted to recapture Kokoda on 8 August without success, the Japanese failed to press their assault, and the next 10 days proved to be a respite for the Australians. The Australians faced significant supply problems despite the modest size of their forces, the Japanese were now increasingly hampered by supply problems of their own as they became overextended, while the Australian defence also became better organised. Regardless, the effectiveness of the Australian units was reduced through exhaustion. On 10 September, Potts handed over command to Porter, who was forced to withdraw to Ioribaiwa, the 25th Brigade under Brigadier Kenneth Eather took over the forward area on 14 September. Heavy fighting continued around Ioribaiwa for the week, and the Australians were again forced to withdraw on 17 September. Having outrun his supply lines and following the reverses suffered by the Japanese at Guadalcanal, Horii was now ordered on to the defensive, marking the limit of the Japanese advance southwards. The Japanese began to withdraw on 24 September to establish a position on the north coast, but they were followed by the Australians under Eather. Further fighting continued into November and December as the Australian and United States forces assaulted the Japanese beachheads, after the fall of Singapore, the Australian government and many Australians feared that Japan would invade the Australian mainland. Additionally, the Army, although large, contained many inexperienced units, in response to this threat, most of the Second Australian Imperial Force was brought back from the Middle East and the Government appealed to the United States for assistance. As a compromise, two brigades of the 6th Division disembarked at Ceylon and formed part of the garrison until they returned to Australia in August 1942. The perceived threat of invasion led to an expansion of the Australian military. By mid-1942, the Army had a strength of ten infantry divisions, the RAAF and RAN were also greatly expanded, though it took years for these services to build up to their peak strengths. Meanwhile, as part of their strategy in the Pacific. The Japanese could have controlled a major route between the Pacific and Indian Oceans and cut off the Australians from American supply ships. The Japanese military considered invading Australia in early 1942 but decided against doing so in February that year, while such an invasion was debated by the Japanese Imperial General Headquarters, it was judged to be beyond the Japanese militarys capabilities and no planning or other preparations were undertaken. The first attempt to capture Port Moresby by seaborne amphibious invasion was thwarted by the Battle of the Coral Sea in May 1942

Burma Campaign
–
The Burmese Independence Army was trained by the Japanese and spearheaded the initial attacks against British Empire forces. The campaign had a number of notable features, the geographical characteristics of the region meant that factors like weather, disease and terrain had a major effect on operations. The lack of transport infrastructure placed an emphasis on engineering and air transport to move and supply troops. The campaign was politically complex, with the British, the United States. It was also the land campaign by the Western Allies in the Pacific Theatre which proceeded continuously from the start of hostilities to the end of the war. This was due to its geographical location, the climate of the region is dominated by the seasonal monsoon rains, which allowed effective campaigning for only just over half of each year. Japanese objectives in Burma were initially limited to the capture of Rangoon and this would close the overland supply line to China and provide a strategic bulwark to defend Japanese gains in British Malaya and the Dutch East Indies. The Japanese successfully attacked over the Kawkareik Pass, and captured the port of Moulmein at the mouth of the Salween River after overcoming stiff resistance and they then advanced northwards, outflanking successive British defensive positions. Troops of the 17th Indian Infantry Division tried to retreat over the Sittaung River, on 22 February, the bridge was demolished to prevent its capture, a decision that has since been extremely contentious. The loss of two brigades of 17th Indian Division meant that Rangoon could not be defended, although some units arrived, counterattacks failed and the new commander of Burma Army, ordered the city to be evacuated on 7 March after its port and oil refinery had been destroyed. The remnants of Burma Army broke out to the north, narrowly escaping encirclement, with the effective collapse of the entire defensive line, there was little choice left other than an overland retreat to India or to Yunnan. After the fall of Rangoon in March 1942, the Allies attempted to make a stand in the north of the country, having been reinforced by a Chinese Expeditionary Force. The Japanese had also reinforced by two divisions made available by the capture of Singapore, and defeated both the newly organised Burma Corps and the Chinese force. The Allies were also faced with growing numbers of Burmese insurgents, with their forces cut off from almost all sources of supply, the Allied commanders finally decided to evacuate their forces from Burma. The retreat was conducted in very difficult circumstances, starving refugees, disorganised stragglers, and the sick and wounded clogged the primitive roads and tracks leading to India. Burma Corps managed to make it most of the way to Imphal, in Manipur in India just before the monsoon broke in May 1942, having lost most of their equipment, there, they found themselves living out in the open under torrential rains in extremely unhealthy circumstances. The army and civil authorities in India were very slow to respond to the needs of the troops, due to lack of communication, when the British retreated from Burma, almost none of the Chinese knew about the retreat. After recuperating they were re-equipped and retrained by American instructors, the rest of the Chinese troops tried to return to Yunnan through remote mountainous forests and out of these, at least half died

Ruhr
–
The Ruhr, or the Ruhr district, Ruhr region, Ruhr area or Ruhr valley, is a polycentric urban area in North Rhine-Westphalia, Germany. With a population density of 2, 800/km² and a population of eight and a million, it is the largest urban agglomeration in Germany. It consists of large, industrial cities bordered by the rivers Ruhr to the south, Rhine to the west. In the southwest it borders the Bergisches Land and it is considered part of the larger Rhine-Ruhr metropolitan region of more than 12 million people, which is among the largest in Europe. The most populous cities are Dortmund, Essen and Duisburg, the Ruhr area has no administrative center, each city in the area has its own administration, although there exists the supracommunal Regionalverband Ruhr institution in Essen. Since the 19th century, these districts have grown together into a complex with a vast industrial landscape. For 2010, the Ruhr region was one of the European Capitals of Culture, the urban landscape of the Ruhr extends from the Lower Rhine Basin east to the Westphalian Plain and south to the hills of the Rhenish Massif. Through the centre of the Ruhr runs a segment of the belt that extends across Germany from west to east. Historically, this belt has underlain some of Germanys richest agricultural regions. Geologically, the region is defined by coal-bearing layers from the upper Carboniferous period, the coal seams reach the surface in a strip along the River Ruhr and dip downward from the river to the north. Beneath the River Lippe, the coal seams lie at a depth of 600 to 800 metres, the thickness of the coal layers ranges from one to three metres. This geological feature played a role in the development of coal mining in the Ruhr. According to the Regionalverband Ruhr,37. 6% of the area is built up. A total of 40. 7% of the land remains in agricultural use. Forests account for 17. 6%, and bodies of water and other types of land use occupy the rest, the inclusion of four mainly rural districts in the otherwise mainly industrial Ruhr helps to explain the large proportion of agricultural and forested land. In addition, the city boroughs of the Ruhr region have outlying districts with a rural character, seen on a map, the Ruhr could be considered a single city, since—at least in the north-south dimension—there are no visible breaks between the individual city boroughs. Thus the Ruhr is described as an urban area, which shares a similar history of urban. Instead, the city boroughs and urban districts of the Ruhr grew independently of one another during the Industrial Revolution

Airborne forces
–
Airborne forces are military units, usually light infantry, set up to be moved by aircraft and dropped into battle, typically by parachute. Thus, they can be placed behind enemy lines, and have the capability to deploy almost anywhere with little warning. The formations are limited only by the number and size of their aircraft, so given enough capacity a huge force can appear out of nowhere in minutes, Major Lewis H. Brereton and his superior Brigadier General Billy Mitchell suggested dropping elements of the U. S. 1st Division behind German lines near Metz, the operation was planned for February 1919 but the war ended before such an attack could be seriously planned. Mitchell conceived that US troops could be trained to utilize parachutes. Following the war, the United States Army Air Service experimented with the concept of having carried on the wings of aircraft pulled off by the opening of their parachutes. The first true paratroop drop was by Italy in November 1927, within a few years several battalions had been raised and were eventually formed into two Folgore and Nembo divisions. Although these would fight with distinction in World War II. Men drawn from the Italian parachute forces were dropped in a special operation in North Africa in 1943 in an attempt to destroy parked aircraft of the United States Army Air Forces. Subsequently, on May 10,1928, Second Lieutenant César Álvarez War Palmas Las voluntarily jumped from a height of 3,000 meters, then on May 16,1928, Major Fernando Melgar Conde and Sergeant 1st. Jose Pineda Castro, jumped from the famous Las Palmas at altitudes of 2,000 and 4,300 meters, at about the same time, the Soviet Union was also experimenting with the idea, planning to drop entire units complete with vehicles and light tanks. To help train enough experienced jumpers, parachute clubs were organized with the aim of transferring into the armed forces if needed, one of the observing parties, Germany, was particularly interested. In 1936, Major F. W. Immans was ordered to set up a school at Stendal. The military had purchased large numbers of Junkers Ju 52 aircraft which were slightly modified for use as paratroop transports in addition to their other duties. The first training class was known as Ausbildungskommando Immans and they commenced the first course on May 3,1936. Other nations, including Argentina, Peru, Japan, France, France became the first nation to organize women in an airborne unit. Recruiting 200 nurses who during peacetime would parachute into natural disasters, several groups within the German armed forces attempted to raise their own paratroop formations, resulting in confusion. As a result, Luftwaffe General Kurt Student was put in command of developing a paratrooper force to be known as the Fallschirmjäger

Cruiser Mk I
–
The Tank, Cruiser, Mk I was a British cruiser tank of the interwar period. It was the first cruiser tank, a fast tank designed to bypass the main lines and engage the enemys lines of communication. The Cruiser Mk II was a heavily armoured adaptation of the Mark I. In 1934, Sir John Carden of Vickers-Armstrong was asked to provide a cheap tank as a replacement for some of the medium models then in use. The pilot model of his design was finished in 1936 and given the designation A9E1 and it incorporated the best features of the earlier Mk III Light Tank, and was powered by a commercial petrol engine. However, this was still in the time of the Great depression and it was the first British tank to have a centrally located turret and to have powered traverse. The system was by Nash & Thompson and similar to that introduced on the Vickers Wellington bomber aircraft. The armour was light, with a maximum of 14 mm thickness, many armour faces were vertical, and there were numerous shot traps, but it could achieve 25 mph and carried the new high velocity QF 2-pounder gun. The drivers compartment and the compartments were not separated. Both of these turrets were permanently manned, which gave the tank a total crew of 6. The A9E1 was tested against other designs and, although lacking in some areas, an order was placed for 125. Seventy-five were built by Harland and Wolff, and the other 50 were built by Vickers, originally, a Rolls-Royce car engine was used, but this proved underpowered and was replaced by an AEC bus engine. The later Valentine Infantry tank essentially used the lower hull and suspension. The A9 weighed 12 long tons, was 19 feet long,8.7 feet high,8.2 feet wide and had a top speed of 25 miles per hour on road and 15 miles per hour off and its maximum road range was 150 miles. The ammunition load was 100 2-pounder rounds and 3,000 rounds for the three Vickers machine guns, the Mark I cruiser began to be delivered in January 1939. The Cruiser was a tank in the French, Greek. The 2 pdr gun was lethal against the early Italian tanks encountered during the North African campaign, the A9s 2-pounder gun could also breach the 20 –30 mm of protective steel on later opponents, such as the Panzer IIID and the Panzer IVD variants. It was effective until the Germans introduced the more thickly armoured Panzer IVE variant to the desert in the Spring of 1941, however, its minimal armour made the A9 very vulnerable to most Axis anti-tank weapons

Cruiser Mk II
–
The Tank, Cruiser, Mk II, was a cruiser tank developed alongside the A9 cruiser tank, and was intended to be a heavier, infantry tank version of that type. In practice, it was not deemed suitable for the tank role and was classified as a heavy cruiser. The A10 was developed by Sir John Carden of Vickers in 1934 by the adaptation of his A9 design, the A10 specification called for armour of up to 1 inch standard, a speed of 10 mph ) was acceptable. The A10 was two tonnes heavier than the A9, but used the same 150 bhp engine, and as a consequence the tanks top speed was cut from 25 miles per hour to 16 miles per hour. The turret armament consisted of a QF 2-pounder gun and a coaxial.303 Vickers machine gun, for the production version, there was a 7.92 mm BESA machine gun mounted in the hull in a barbette to the right of the driver. This was added to give extra firepower, but at the expense of simplicity - the Vickers, the tank had a crew of five. There was no separation between the drivers compartment and the fighting compartments, the prototype was completed in 1936, a few months after the A9 prototype. Carden had died in an air crash in 1935 and development was slower than expected, in 1937, the A10 was dropped as an infantry support tank, but in 1938 it was decided to produce it as a heavy cruiser. The A10 was accepted for service - initially as Tank, Cruiser, Heavy Mk I and then Tank, Cruiser A10 Mk I and finally Tank, production was ordered in July 1938. Total production was 175 vehicles, including the 30 CS versions,45 were built by Birmingham Railway Carriage, in late 1939, another order was placed with Birmingham Railway Carriage and Wagon Company, this time for a larger order of 75 vehicles. A number of Mark IIs were part of the British Expeditionary Force sent to France in the stages of the Second World War. Classified as a cruiser,31 were sent to France with the 1st Armoured Division. The tank also served in the North African Campaign until late 1941, the coaxial Vickers machine guns were replaced with BESA machine guns. The CS version of the Mark II had a 3.7 inches howitzer in the turret instead of the 2-pdr, the standard ammunition load was 40 rounds smoke, and a few HE shells. This weapon was derived from a World War I field howitzer, the QF3. 7-inch mountain howitzer

Interrupted screw
–
An interrupted screw or interrupted thread is a mechanical device typically used in the breech of artillery guns. It is believed to have invented in 1845. It is a screw that has a section of thread along its axis removed, the screw is mated with a partially threaded hole at the rear of the weapons chamber, where the screw has threads the hole has none, and vice versa. The screw can thus be smoothly inserted all the way into the gun, an earlier method was the use of a wedge to block the rear of the gun. Sealing was further improved with the de Bange obturator in 1872, the major weakness of the original designs was that only half of the circumference of the breechblock could be threaded, hence a fairly long breechblock was still required to achieve a secure lock. Axel Welin solved this problem with his stepped interrupted screw design and this design has threads of the block and breech cut in steps of successively larger radius. This is the design still in use with bagged charge artillery. Rifled breech loader Welin breech block Interrupted screw breech mechanisms Navweaps. com Interrupted threads used on naval guns

Universal Carrier
–
The vehicle was used widely by British Commonwealth forces during the Second World War. Universal Carriers were usually used for transporting personnel and equipment, mostly support weapons, with some 113,000 built by 1960 in the United Kingdom and abroad, it is the most produced armoured fighting vehicle in history. The origins of the Universal Carrier family can be traced back generally to the Carden Loyd tankettes family, which was developed in the 1920s, and specifically the Mk VI tankette. In 1934, Vickers-Armstrongs produced, as a venture, a light tracked vehicle that could be used either to carry a machine gun or to tow a light field gun. The VA. D50 had a box at the front for driver. The War Office considered it as a replacement for their Dragon artillery tractors. One was built as the Carrier, Machine-Gun Experimental carrying a machine gun, a small number of this design as Carrier, Machine-Gun No 1 Mark 1 were built and entered service in 1936. Some were converted into pilot models for the Machine gun Carrier, Cavalry Carrier, the carrier put the driver and commander at the front sitting side-by-side, the driver to the right. The Ford Flathead V8 engine that powered it was placed in the centre of the vehicle with the drive at the rear. The suspension and running gear were based on that used on the Vickers light tank series using Horstmann springs, directional control was through a steering wheel. Small turns moved the front road wheel assembly warping the track so the vehicle drifted to that side, further movement of the wheel braked the appropriate track to give a turn. The hull in front of the commanders position jutted forward to give room for the Bren gun to fire through a simple slit, to either side of the engine were two areas in which passengers could ride or stores could be carried. Initially, there were several types of Carrier that varied slightly in design according to their purpose, Medium Machine Gun Carrier, Bren Gun Carrier, Scout Carrier and Cavalry Carrier. However, production of a model came to be preferred and the Universal design appeared in 1940. It differed from the models in that the rear section of the body had a rectangular shape. Production of Carriers began in 1934 and ended in 1960, with the introduction of the Universal, production in the UK was undertaken by Aveling-Barford, Ford, Sentinel, Thornycroft, and Wolseley Motors. By 1945 production amounted to approximately 57,000 of all models, the Universal Carriers, in different variants, were also produced in allied countries. Ford Motor Company of Canada manufactured about 29,000 vehicles known as the Ford C01UC Universal Carrier, smaller numbers of them were also produced in Australia, where hulls were made in several places in Victoria and by South Australian Railways workshops in Adelaide, South Australia

Jeep
–
Jeep is a brand of American automobiles that is a division of FCA US LLC, a wholly owned subsidiary of Fiat Chrysler Automobiles. The former Chrysler Corporation acquired the Jeep brand, along with the assets of its owner American Motors. The division is headquartered in Toledo, Ohio, Jeeps current product range consists solely of sport utility vehicles and off-road vehicles, but has also included pickup trucks in the past. The original Jeep was the prototype Bantam BRC, Willys MB Jeeps went into production in 1941 specifically for the military, arguably making them the oldest four-wheel drive mass-production vehicles now known as SUVs. The Jeep became the primary light 4-wheel-drive vehicle of the United States Army, the term became common worldwide in the wake of the war. Doug Stewart notes, The spartan, cramped, and unstintingly functional jeep became the ubiquitous World War II four-wheeled personification of Yankee ingenuity and cocky, the first civilian models were produced in 1945. It inspired a number of light utility vehicles, such as the Land Rover. Many Jeep variants serving similar military and civilian roles have since been designed in other nations, only two companies responded to the request, American Bantam Car Company and Willys-Overland. The Army had set what seemed like an impossible deadline of 49 days to supply a working prototype, Willys asked for more time, but was refused. The bankrupt American Bantam Car Company had no engineering staff left on the payroll and solicited Karl Probst, after turning down Bantams initial request, Probst responded to an Army request and commenced work, initially without salary, on July 17,1940. Probst laid out plans for the Bantam prototype, known as the BRC or Bantam Reconnaissance Car. Bantams bid was submitted, complete with blueprints, on July 22, while much of the vehicle could be assembled from off-the-shelf automotive parts, custom four-wheel drivetrain components were to be supplied by Spicer. The hand-built prototype was completed in Butler, Pennsylvania, and driven to Camp Holabird, Maryland, the vehicle met all the Armys criteria except engine torque. The resulting Ford Pygmy and Willys Quad prototypes looked very similar to the Bantam BRC prototype, fifteen hundred of each of the three models were built and extensively field-tested. Delmar Barney Roos, Willys-Overlands chief engineer, made changes to meet a revised weight specification. He was thus able to use the powerful but comparatively heavy Willys Go Devil engine, the Willys version of the car would become the standardized Jeep design, designated the model MB and was built at their plant in Toledo, Ohio. The familiar pressed-metal Jeep grille was actually a Ford design feature, the Army chose Ford as the second supplier, building Jeeps to the Willys design. Willys supplied Ford with a set of plans and specifications

Cordite
–
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low explosive because of its slow burning rates and these produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, Cordite was used initially in the. Cordite was also used for weapons, such as tank guns, artillery. It has been used mainly for this purpose since the late 19th century by the UK and its use was further developed before World War II, and as 2-and-3-inch-diameter Unrotated Projectiles for launching anti-aircraft weapons. Small cordite rocket charges were developed for ejector seats made by the Martin-Baker Company. Cordite was also used in the system of the Little Boy atomic bomb dropped over Hiroshima in August 1945. The term cordite generally disappeared from official publications between the wars, during World War II double based propellants were very widely used and there was some use of triple based propellants by artillery. For small arms it has replaced by other propellants, such as the Improved Military Rifle line of extruded powder or the WC844 ball propellant currently in use in the 5. 56×45mm NATO. Production ceased in the United Kingdom, around the end of the 20th century, with the closure of the last of the World War II cordite factories, triple base propellant for UK service is now manufactured in Germany. Gunpowder, a mixture of sulfur, charcoal and potassium nitrate, was the original propellant employed in firearms. It was used from about 10th or 11th century onwards, but it had disadvantages, the first smokeless powder was developed in 1865 by Major Johann F. E. Schultze of the Prussian artillery. His formulation was composed of nitrolignose impregnated with saltpetre or barium nitrate, in 1882 the Explosive Company of Stowmarket introduced EC Powder, which contained nitro-cotton and nitrates of potassium and barium in a grain gelatinesed by ether alcohol. It had coarser grains than other nitrocellulose powders and it proved unsuitable for rifles, but it remained in long use for shotguns and was later used for grenades and fragmentation bombs. In 1884, the French chemist Paul Vieille produced a smokeless propellant that had some success and it was made out of collodion, resulting in a plastic colloidal substance which was rolled into very thin sheets, then dried and cut up into small flakes. It was immediately adopted by the French military for their Mle 1886 infantry rifle, the rifle and the cartridge developed to use this powder were known generically as the 8mm Lebel, after the officer who developed its 8 mm full metal jacket bullet. The following year,1887, Alfred Nobel invented and patented a smokeless propellant he called Ballistite and it was composed of 10% camphor, 45% nitroglycerine and 45% collodion. Over time the camphor tended to evaporate, leaving an unstable explosive, using acetone as a solvent, it was extruded as spaghetti-like rods initially called cord powder or the Committees modification of Ballistite, but this was swiftly abbreviated to Cordite

Imperial War Museum Duxford
–
Imperial War Museum Duxford is a branch of the Imperial War Museum near Duxford in Cambridgeshire, England. Britains largest aviation museum, Duxford houses the large exhibits, including nearly 200 aircraft, military vehicles, artillery. The site also provides space for the museums other collections of material such as film, photographs, documents, books. The site accommodates several British Army regimental museums, including those of the Parachute Regiment, based on the historic Duxford Aerodrome, the site was originally operated by the Royal Air Force during the First World War. Duxford remained an active RAF airfield until 1961, after the Ministry of Defence declared the site surplus to requirements in 1969 the Imperial War Museum received permission to use part of the site for storage. The entirety of the site was transferred to the museum in February 1976, in keeping with the sites history many of Duxfords original buildings, such as hangars used during the Battle of Britain, are still in use. The site also features several purpose-built exhibition buildings, such as the Stirling Prize-winning American Air Museum, the site remains an active airfield and is used by civilian flying companies, and hosts regular air shows. The museum opened in 1920, by which point it had renamed the Imperial War Museum. With the outbreak of the Second World War, the terms of reference were enlarged to include the conflict. The museums terms of reference was broadened again in 1953 to include all conflicts in which British or Commonwealth forces were engaged. Although the museums south London home had been extended in 1966, Duxford featured three double bay hangars of First World War vintage, which together provided over 9000 m2 of space. Within two years, ten of the aircraft had been brought to Duxford, and were being restored by volunteers of the East Anglia Aviation Society. While the museums own aircraft were not restored to flying condition, further air shows followed, with a display in June 1976 attracting an audience of 45,000 people. The runway was bought by Cambridgeshire County Council in 1977, the success of these shows provided a valuable source of revenue, and complemented the efforts of volunteers, so that the museum applied for the permanent transfer of the entire site to its use. Permission was received in February 1976 and Duxford became the first outstation of the Imperial War Museum, initially open from March–October, Duxford received 167,000 visitors in the 1977 season, and 340,000 in 1978.

Other neighborhoods were Neve Shalom, Yafa Nof, Achva, Ohel Moshe, Kerem HaTeimanim, once Tel Aviv received city status in the 1920s, those neighborhoods joined the newly formed municipality, now becoming separated from Jaffa. The Second Aliyah led to further expansion, in 1906, a group of Jews, among them residents of Jaffa, followed the initiative of Akiva Aryeh Weiss and banded together to form the Ahuzat Bayit society.

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker
