Military
–
The armed forces of a country are its government-sponsored defense, fighting forces, and organizations. They exist to further the foreign and domestic policies of their body and to defend that body. Armed force is the use of armed forces to achieve political objectives, the study of the use of armed forces is called military science. Broadly speaking, this involves considering offense and defense at three levels, strategy, operational art, and tactics, all three levels study the application of the use of force in order to achieve a desired objective. In most countries the basis of the forces is the military. However, armed forces can include other paramilitary structures, the obvious benefit to a country in maintaining armed forces is in providing protection from foreign threats and from internal conflict. In recent decades armed forces personnel have also used as emergency civil support roles in post-disaster situations. On the other hand, they may harm a society by engaging in counter-productive warfare. Expenditure on science and technology to develop weapons and systems sometimes produces side benefits, although some claim that greater benefits could come from targeting the money directly

Artillery
–
Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantrys small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, as technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today, modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an armys total firepower, in its earliest sense, the word artillery referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. In common speech, the artillery is often used to refer to individual devices, along with their accessories and fittings. However, there is no generally recognised generic term for a gun, howitzer, mortar, and so forth, the United States uses artillery piece, the projectiles fired are typically either shot or shell. Shell is a widely used term for a projectile, which is a component of munitions. By association, artillery may also refer to the arm of service that customarily operates such engines, in the 20th Century technology based target acquisition devices, such as radar, and systems, such as sound ranging and flash spotting, emerged to acquire targets, primarily for artillery. These are usually operated by one or more of the artillery arms, Artillery originated for use against ground targets—against infantry, cavalry and other artillery. An early specialist development was coastal artillery for use against enemy ships, the early 20th Century saw the development of a new class of artillery for use against aircraft, anti-aircraft guns. Artillery is arguably the most lethal form of land-based armament currently employed, the majority of combat deaths in the Napoleonic Wars, World War I, and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was the God of War, although not called as such, machines performing the role recognizable as artillery have been employed in warfare since antiquity. The first references in the historical tradition begin at Syracuse in 399 BC. From the Middle Ages through most of the era, artillery pieces on land were moved by horse-drawn gun carriages. In the contemporary era, the artillery and crew rely on wheeled or tracked vehicles as transportation, Artillery used by naval forces has changed significantly also, with missiles replacing guns in surface warfare. The engineering designs of the means of delivery have likewise changed significantly over time, in some armies, the weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery, the actions involved in operating the piece are collectively called serving the gun by the detachment or gun crew, constituting either direct or indirect artillery fire. The term gunner is used in armed forces for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either crews or detachments, several such crews and teams with other functions are combined into a unit of artillery, usually called a battery, although sometimes called a company

Small arms
–
In international arms control, small arms include revolvers and pistols, rifles and carbines, assault rifles, submachine guns and light machine guns. Together with light weapons, they comprise the Small Arms and Light Weapons protocol, in the U. S. military, small arms are man portable, individual, and crew-served weapon systems used mainly against personnel and lightly armored or unarmored equipment. However, in regard to management, the U. S. Army says small arms/light weapons are, Handguns, shoulder-fired weapons, light automatic weapons up to. Much of the work to address the illegal arms trade is raised in the United Nations Conference on the Illicit Trade in Small Arms. In 2013, the Small Arms Survey said that of the 875 million small arms distributed globally,650 million — almost 75 percent — are in civilian hands, about 200 million are controlled by armed forces and about 26 million by law enforcement agencies. Gang members hold between 2 and 10 million small arms and armed, non-state actors hold about 1.4 million, together, the small-arms arsenals of non-state actors and gangs account for 0.4 to 1.3 percent of the global total.

Ammunition
–
Ammunition is the general term used for the material fired, scattered, dropped or detonated from any weapon. The term ammunition can be traced back to the mid 17th century, broadly speaking, ammunition refers to both expendable weapons and the component parts of other weapons that create the effect on a target. Nearly all weapons will require some form of ammunition to operate, the word comes from the French la munition, which refers to the material used for war. The terms ammunition and munitions are used interchangeably, although the term munition now usually refers to both the actual weapons system alongside the ammunition required to operate it. The purpose of ammunition is to project a force against a target to have an effect. The most iconic example of ammunition is the cartridge, which all components required to deliver the weapon effect in a single package. Ammunition comes in a range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain types that enable their use across different weapons. There are also types of ammunition that are designed to have a specialized effect on a target, such as armor-piercing shells and tracer ammunition. Ammunition is commonly colored in a manner to assist in the identification. A round is a cartridge containing a projectile, propellant, primer. A shell is a form of ammunition that is fired by a large cannon or artillery piece. Before the mid-19th century, these shells were made of solid materials. However, since that time, they are often filled with high-explosives. A shot refers to a release of a weapons system. This may involve firing just one round or piece of ammunition, a dud refers to loaded ammunition that fails to function as intended, typically failing to detonate on landing. However, it can refer to ammunition that fails to fire inside the weapon, known as a misfire, or when the ammunition only partially functions. Dud ammunition, which is classified as an ordnance, is regarded as highly dangerous

Division (military)
–
A division is a large military unit or formation, usually consisting of between 10,000 and 20,000 soldiers. Infantry divisions during the World Wars ranged between 10,000 and 30,000 in nominal strength, in most armies, a division is composed of several regiments or brigades, in turn, several divisions typically make up a corps. In the West, the first general to think of organising an army into smaller units was Maurice de Saxe, Marshal General of France. He died at the age of 54, without having implemented his idea, victor-François de Broglie put the ideas into practice. He conducted successful practical experiments of the system in the Seven Years War. The first war in which the system was used systematically was the French Revolutionary War. It made the more flexible and easy to manoeuvre. Under Napoleon, the divisions were grouped together into corps, because of their increasing size, napoleons military success spread the divisional and corps system all over Europe, by the end of the Napoleonic Wars, all armies in Europe had adopted it. In modern times, most military forces have standardized their divisional structures, the peak use of the division as the primary combat unit occurred during World War II, when the belligerents deployed over a thousand divisions. With technological advances since then, the power of each division has increased. Divisions are often formed to organize units of a particular type together with support units to allow independent operations. In more recent times, divisions have mainly been organized as combined arms units with subordinate units representing various combat arms, in this case, the division often retains the name of a more specialized division, and may still be tasked with a primary role suited to that specialization. For the most part, large cavalry units did not remain after World War II, in general, two new types of cavalry were developed, air cavalry or airmobile, relying on helicopter mobility, and armored cavalry, based on an autonomous armored formation. The former was pioneered by the 11th Air Assault Division, formed on 1 February 1963 at Fort Benning, on 29 June 1965 the division was renamed as the 1st Cavalry Division, before its departure for the Vietnam War. After the end of the Vietnam War, the 1st Cavalry Division was reorganised and re-equipped with tanks, the development of the tank during World War I prompted some nations to experiment with forming them into division-size units. Many did this the way as they did cavalry divisions, by merely replacing cavalry with AFVs. This proved unwieldy in combat, as the units had many tanks, instead, a more balanced approach was taken by adjusting the number of tank, infantry, artillery, and support units. A panzer division was a division of the Wehrmacht and the Waffen-SS of Germany during World War II

Brigade
–
A brigade is a major tactical military formation that is typically composed of three to six battalions plus supporting elements. It is roughly equivalent to an enlarged or reinforced regiment, two or more brigades may constitute a division. Brigades formed into divisions are usually infantry or armored, in addition to combat units, they may include combat support units or sub-units, such as artillery and engineers, and logistic units or sub-units. Historically, such brigades have sometimes been called brigade-groups, on operations, a brigade may comprise both organic elements and attached elements, including some temporarily attached for a specific task. Brigades may also be specialized and comprise battalions of a branch, for example cavalry, mechanized, armored, artillery, air defence, aviation, engineers. Some brigades are classified as independent or separate and operate independently from the division structure. The typical NATO standard brigade consists of approximately 3,200 to 5,500 troops, however, in Switzerland and Austria, the numbers could go as high as 11,000 troops. The Soviet Union, its forerunners and successors, mostly use regiment instead of brigade, a brigades commander is commonly a major general, brigadier general, brigadier or colonel. In some armies, the commander is rated as a General Officer, the brigade commander has a self-contained headquarters and staff. Some brigades may also have a deputy commander, the headquarters has a nucleus of staff officers and support that can vary in size depending on the type of brigade. On operations, additional specialist elements may be attached, the headquarters will usually have its own communications unit. In some gendarmerie forces, brigades are the organizational unit. The brigade as a military unit came about starting in the 15th century when the British army, as such a field army became larger, the number of subordinate commanders became unmanageable for the officer in general command of said army, usually a major general, to effectively command. In order to streamline command relationships, as well as effect some modicum of control, especially in regard to combined arms operations. The terms origin is found in two French roots, which together, meant roughly those who fight, the so-called brigada was a well-mixed unit, comprising infantry, cavalry and normally also artillery, designated for a special task. The size of such brigada ranged from a company of up to two regiments. The brigada was the forerunner of the battalion task force, battle group. The brigade was improved as a unit by the Swedish king Gustavus Adolphus

Machine gun
–
A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Note that not all fully automatic firearms are machine guns, submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. Many machine guns also use belt feeding and open bolt operation, unlike semi-automatic firearms, which require one trigger pull per round fired, a machine gun is designed to fire for as long as the trigger is held down. Nowadays the term is restricted to heavy weapons, able to provide continuous or frequent bursts of automatic fire for as long as ammunition lasts. Machine guns are used against personnel, aircraft and light vehicles, or to provide suppressive fire. Some machine guns have in practice sustained fire almost continuously for hours, because they become very hot, practically all machine guns fire from an open bolt, to permit air cooling from the breech between bursts. They also usually have either a barrel cooling system, slow-heating heavyweight barrel, although subdivided into light, medium, heavy or general-purpose, even the lightest machine guns tend to be substantially larger and heavier than standard infantry arms. Medium and heavy guns are either mounted on a tripod or on a vehicle, when carried on foot. Medium machine guns use full-sized rifle rounds and are designed to be used from fixed positions mounted on a tripod. 50in, the M249 automatic rifle is operated by an automatic rifleman, but its ammunition may be carried by other Soldiers within the squad or unit. The M249 machine gun is a crew-served weapon, Machine guns usually have simple iron sights, though the use of optics is becoming more common. Many heavy machine guns, such as the Browning M2.50 caliber machine gun, are enough to engage targets at great distances. During the Vietnam War, Carlos Hathcock set the record for a shot at 7382 ft with a.50 caliber heavy machine gun he had equipped with a telescopic sight. This led to the introduction of.50 caliber anti-materiel sniper rifles, selective fire rifles firing a full-power rifle cartridge from a closed bolt are called automatic rifles or battle rifles, while rifles that fire an intermediate cartridge are called assault rifles. Unlocking and removing the spent case from the chamber and ejecting it out of the weapon as bolt is moving rearward Loading the next round into the firing chamber. Usually the recoil spring tension pushes bolt back into battery and a cam strips the new round from a feeding device, cycle is repeated as long as the trigger is activated by operator. Releasing the trigger resets the trigger mechanism by engaging a sear so the weapon stops firing with bolt carrier fully at the rear, the operation is basically the same for all autoloading firearms, regardless of the means of activating these mechanisms. Most modern machine guns use gas-operated reloading, a recoil actuated machine gun uses the recoil to first unlock and then operate the action. Machine guns such as the M2 Browning and MG42, are of this type, a cam, lever or actuator demultiplicates the energy of the recoil to operate the bolt

Infantry
–
Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare, Infantry can enter and maneuver in terrain that is inaccessible to military vehicles and employ crew-served infantry weapons that provide greater and more sustained firepower. In English, the 16th-century term Infantry describes soldiers who walk to the battlefield, and there engage, fight, the term arose in Sixteenth-Century Spain, which boasted one of the first professional standing armies seen in Europe since the days of Rome. It was common to appoint royal princes to military commands, and the men under them became known as Infanteria. in the Canadian Army, the role of the infantry is to close with, and destroy the enemy. In the U. S. Army, the closes with the enemy, by means of fire and maneuver, in order to destroy or capture him, or to repel his assault by fire, close combat. In the U. S. Marine Corps, the role of the infantry is to locate, close with, and destroy the enemy fire and maneuver. Beginning with the Napoleonic Wars of the early 19th century, artillery has become a dominant force on the battlefield. Since World War I, combat aircraft and armoured vehicles have become dominant. In 20th and 21st century warfare, infantry functions most effectively as part of a combined arms team including artillery, armour, Infantry relies on organized formations to be employed in battle. These have evolved over time, but remain a key element to effective infantry development and deployment, until the end of the 19th century, infantry units were for the most part employed in close formations up until contact with the enemy. This allowed commanders to control of the unit, especially while maneuvering. The development of guns and other weapons with increased firepower forced infantry units to disperse in order to make them less vulnerable to such weapons. This decentralization of command was made possible by improved communications equipment, among the various subtypes of infantry is Medium infantry. This refers to infantry which are heavily armed and armored than heavy infantry. In the early period, medium infantry were largely eliminated due to discontinued use of body armour up until the 20th century. In the United States Army, Stryker Infantry is considered Medium Infantry, since they are heavier than light infantry, Infantry doctrine is the concise expression of how infantry forces contribute to campaigns, major operations, battles, and engagements. It is a guide to action, not a set of hard, doctrine provides a very common frame of reference across the military forces, allowing the infantry to function cooperatively in what are now called combined arms operations. Doctrine helps standardise operations, facilitating readiness by establishing common ways of accomplishing infantry tasks, doctrine links theory, history, experimentation, and practice

Rifle
–
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves cut into the barrel walls. The raised areas of the rifling are called lands, which contact with the projectile. When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling and this allows the use of aerodynamically-efficient bullets and thus improves range and accuracy. The word rifle originally referred to the grooving, and a rifle was called a rifled gun, the word rifle is now used for any long hand-held aimed device activated by a trigger, such as Air rifles and the Personnel halting and stimulation response rifle. Rifles are used in warfare, hunting and shooting sports, formerly, rifles only fired a single projectile with each squeeze of the trigger. Modern rifles are capable of firing more than one round per trigger squeeze, some fire in an automatic mode. Thus, modern automatic rifles overlap to some extent in design, in fact, many light machine guns are adaptations of existing automatic rifle designs. A militarys light machine guns are chambered for the same caliber ammunition as its service rifles. Generally, the difference between a rifle and a machine gun comes down to weight, cooling system. Modern military rifles are fed by magazines, while machine guns are generally belt-fed, many machine guns allow the operator to quickly exchange barrels in order to prevent overheating, whereas rifles generally do not. Most machine guns fire from a bolt in order to reduce the danger of cook-off. Machine guns are often crewed by more than one soldier, the rifle is an individual weapon, the term rifle is sometimes used to describe larger crew-served rifled weapons firing explosive shells, for example, recoilless rifles. In many works of fiction a rifle refers to any weapon that has a stock and is shouldered before firing, the origins of rifling are difficult to trace, but some of the earliest practical experiments seem to have occurred in Europe during the 15th century. Archers had long realized that a twist added to the feathers of their arrows gave them greater accuracy. This might also have led to a increase in accuracy. Rifles were created as an improvement in the accuracy of smooth bore muskets, the black powder used in early muzzle-loading rifles quickly fouled the barrel, making loading slower and more difficult. Since musketeers could not afford to take the time to stop and clean their barrels in the middle of a battle, rifles were limited to use by sharpshooters, muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at relatively low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle

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

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

QF 1-pounder pom-pom
–
The QF1 pounder, universally known as the pom-pom due to the sound of its discharge, was a 37 mm British autocannon, the first of its type in the world. It was used by several countries initially as an infantry gun, hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun. Early versions were sold under the Maxim-Nordenfelt label, whereas versions in British service were labelled Vickers, Sons and they are all effectively the same gun. The Belgian Army used the gun on a field carriage mounting. A version was produced in Germany for both Navy and Army, in World War I, it was used in Europe as an anti-aircraft gun as the Maxim Flak M14. Four guns were used mounted on carriages in the German campaign in South West Africa in 1915. The British government initially rejected the gun but other countries bought it, in the Second Boer War, the British found themselves being fired on with success by the Boers with their 37 mm Maxim-Nordenfelt versions with ammunition made in Germany. In response, Vickers-Maxim of Britain shipped either 57 or 50 guns out to the British Army in South Africa and these early Mk I versions were mounted on typical field gun type carriages. In World War I, it was used as an early anti-aircraft gun in the defence of Britain. 25 were employed in August 1914, and 50 in February 1916, a Mk II gun on a Naval pedestal mounting was the first to open fire in defence of London during the war. However, the shell was insufficient to damage the German Zeppelin airships sufficiently to bring them down. The Ministry of Munitions noted in 1922, The pom-poms were of little value. There was no shrapnel available for them, and the provided for them would not burst on aeroplane fabric. Were of no use except at a lower elevation than a Zeppelin attacking London was likely to keep. Hogg of No.2 AA Section in III Corps was the first anti-aircraft gunner to shoot down an aircraft, with 75 rounds on 23 September 1914 in France. The gun was mounted on aircraft as the lighter 1-pounder Mk III. As a light gun, it was quickly replaced by the larger QF 1½ pounder. The British are reported to have used some Common pointed shells in the Boer War

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

Cavalry
–
Cavalry or horsemen were soldiers or warriors who fought mounted on horseback. Cavalry were historically the most mobile of the combat arms, an individual soldier in the cavalry is known by a number of designations such as cavalryman, horseman, dragoon or trooper. The designation of cavalry was not usually given to any military forces that used animals, such as camels. Cavalry had the advantage of improved mobility, and a man fighting from horseback also had the advantages of greater height, speed, another element of horse mounted warfare is the psychological impact a mounted soldier can inflict on an opponent. In Europe cavalry became increasingly armoured, and eventually became known for the mounted knights, in the period between the World Wars, many cavalry units were converted into motorized infantry and mechanized infantry units, or reformed as tank troops. Most cavalry units that are horse-mounted in modern armies serve in purely ceremonial roles, modern usage of the term generally refers to specialist units equipped with tanks or aircraft. The shock role, traditionally filled by heavy cavalry, is filled by units with the armored designation. Before the Iron Age, the role of cavalry on the battlefield was largely performed by light chariots, the chariot originated with the Sintashta-Petrovka culture in Central Asia and spread by nomadic or semi-nomadic Indo-Iranians. The power of mobility given by mounted units was recognized early on, Cavalry techniques were an innovation of equestrian nomads of the Central Asian and Iranian steppe and pastoralist tribes such as the Persian Parthians and Sarmatians. The photograph above left shows Assyrian cavalry from reliefs of 865–860 BC, at this time, the men had no spurs, saddles, saddle cloths, or stirrups. Fighting from the back of a horse was more difficult than mere riding. The cavalry acted in pairs, the reins of the archer were controlled by his neighbours hand. Even at this time, cavalry used swords, shields. The sculpture implies two types of cavalry, but this might be a simplification by the artist, Later images of Assyrian cavalry show saddle cloths as primitive saddles, allowing each archer to control his own horse. As early as 490 BC a breed of horses was bred in the Nisaean plain in Media to carry men with increasing amounts of armour. However, chariots remained in use for purposes such as carrying the victorious general in a Roman triumph. The southern Britons met Julius Caesar with chariots in 55 and 54 BC, the last mention of chariot use in battle was by the Caledonians at the Mons Graupius, in 84 AD. During the classical Greek period cavalry were usually limited to citizens who could afford expensive war-horses

Regiment
–
A regiment is a military unit. Their role and size varies markedly, depending on the country, in Medieval Europe, the term regiment denoted any large body of front-line soldiers, recruited or conscripted in one geographical area, by a leader who was often also the feudal lord of the soldiers. By the 17th century, a regiment was usually about a thousand personnel. In many armies, the first role has been assumed by independent battalions, battlegroups, task forces, brigades and other, similarly-sized operational units. By the beginning of the 18th century, regiments in most European continental armies had evolved into permanent units with distinctive titles and uniforms, when at full strength, an infantry regiment normally comprised two field battalions of about 800 men each or 8–10 companies. In some armies, an independent regiment with fewer companies was labelled a demi-regiment, a cavalry regiment numbered 600 to 900 troopers, making up a single entity. With the widespread adoption of conscription in European armies during the nineteenth century, the regimental system underwent modification. Prior to World War I, a regiment in the French, German, Russian. As far as possible, the battalions would be garrisoned in the same military district, so that the regiment could be mobilized. A cavalry regiment by contrast made up an entity of up to 1,000 troopers. Usually, the regiment is responsible for recruiting and administering all of a military career. Depending upon the country, regiments can be either combat units or administrative units or both and this is often contrasted to the continental system adopted by many armies. Generally, divisions are garrisoned together and share the same installations, thus, in divisional administration, soldiers and officers are transferred in and out of divisions as required. Some regiments recruited from specific areas, and usually incorporated the place name into the regimental name. In other cases, regiments would recruit from an age group within a nation. In other cases, new regiments were raised for new functions within an army, e. g. the Fusiliers, the Parachute Regiment, a key aspect of the regimental system is that the regiment or battalion is the fundamental tactical building block. This flows historically from the period, when battalions were widely dispersed and virtually autonomous. For example, a regiment might include different types of battalions of different origins, within the regimental system, soldiers, and usually officers, are always posted to a tactical unit of their own regiment whenever posted to field duty

Public domain
–
The term public domain has two senses of meaning. Anything published is out in the domain in the sense that it is available to the public. Once published, news and information in books is in the public domain, in the sense of intellectual property, works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, or are inapplicable. Examples for works not covered by copyright which are therefore in the domain, are the formulae of Newtonian physics, cooking recipes. Examples for works actively dedicated into public domain by their authors are reference implementations of algorithms, NIHs ImageJ. The term is not normally applied to situations where the creator of a work retains residual rights, as rights are country-based and vary, a work may be subject to rights in one country and be in the public domain in another. Some rights depend on registrations on a basis, and the absence of registration in a particular country, if required. Although the term public domain did not come into use until the mid-18th century, the Romans had a large proprietary rights system where they defined many things that cannot be privately owned as res nullius, res communes, res publicae and res universitatis. The term res nullius was defined as not yet appropriated. The term res communes was defined as things that could be enjoyed by mankind, such as air, sunlight. The term res publicae referred to things that were shared by all citizens, when the first early copyright law was first established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by British and French jurists in the eighteenth century, instead of public domain they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law. The phrase fall in the domain can be traced to mid-nineteenth century France to describe the end of copyright term. In this historical context Paul Torremans describes copyright as a coral reef of private right jutting up from the ocean of the public domain. Because copyright law is different from country to country, Pamela Samuelson has described the public domain as being different sizes at different times in different countries. According to James Boyle this definition underlines common usage of the public domain and equates the public domain to public property. However, the usage of the public domain can be more granular. Such a definition regards work in copyright as private property subject to fair use rights, the materials that compose our cultural heritage must be free for all living to use no less than matter necessary for biological survival
