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 Mountain guns are largely outdated, their role being filled by mortars, multiple rocket launchers, recoilless rifles, most modern artillery is manufactured from light-weight materials and can be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
