.55 Boys
The .55 Boys (13.9×99mmB in metric) is an anti-tank cartridge used by the United Kingdom during World War II. It was designed for use with the Boys anti-tank rifle. Design The .55 Boys is a 13.2×99mm Hotchkiss cartridge, necked up in the mid-1930s to accept a .55 caliber bullet. Since the case was left with less of a shoulder, a belt was added to ensure reliable headspacing. The .55 Boys performed poorly compared to contemporary foreign anti-tank rounds, such as the German 7.92×94mm PatronenA smaller tungsten-cored round fired from a case about the same size as the Boys and the Soviet 14.5×114mm rounds. As a result, it was quickly deemed obsolete.''Ammo Encyclopedia'', Second Edition by Michael Bussard, p. 563 History The concept of a small arms round for use against tanks began with the German 13.2mm TuF round, designed during World War I to counter the first British tanks. In the 1930s, the United Kingdom began designing an anti-tank rifle to address the threat po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Royal Small Arms Factory
The Royal Small Arms Factory (RSAF), also known by the metonym ''Enfield'', was a UK government-owned rifle factory in Enfield, adjoining the Lee Navigation in the Lea Valley. Some parts were in Waltham Abbey. The factory produced British military rifles, muskets and swords from 1816. It closed in 1988, but some of its work was transferred to other sites. The factory designed and manufactured many famous British Army weapons including the Lee–Enfield rifles which were standard equipment during both World Wars. History The RSAF had its origins in a short-lived Royal Manufactory of Small Arms established in Lewisham in 1807. The site in Lewisham was a mill where armour had been made since the fourteenth century. Following its purchase by Henry VIII in 1530, it became known as the Royal Armoury Mills and served his armoury in Greenwich. During the Napoleonic War, the increasing demand for large quantities of reliable weapons prompted the Board of Ordnance to look into bu ...

Military Cartridges
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction ...

Pistol And Rifle Cartridges
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the lack of a buttstock) and strict laws and regulations governing their manufactur ...

Tungsten
Tungsten (also called wolfram) is a chemical element; it has symbol W and atomic number 74. It is a metal found naturally on Earth almost exclusively in compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternative name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at . It also has the highest boiling point, at . Its density is 19.254 g/cm3, comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work into metal. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many alloys ...

Armour-piercing Ammunition
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly armoured targets such as body armour, bulletproof glass, and lightly armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at a very-high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. Penetration In the context of weaponry, ''penetration'' is the ability of a weapon or projectile to pierce into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Home Guard (United Kingdom)
The Home Guard (initially Local Defence Volunteers or LDV) was an unpaid armed citizen militia supporting the 'Home Forces' of the British Army during the Second World War. Operational from 1940 to 1944, the Home guard, Home Guard comprised more than 1.5 million local volunteers otherwise ineligible for military service, such as those who were too young, too old or medically unfit to join the regular British Armed Forces, armed services (regular military service was restricted to those aged 18 to 41) and those in reserved occupations. Excluding those already in the armed services, the civilian police or other civil defence volunteer organisations, approximately one in five men were Home Guard volunteers. Their primary role was to act as a secondary defence force in their home locality in case of Operation Sea Lion, invasion by the forces of Nazi Germany. The Home Guard were initially ordered to observe, and report back to General Headquarters Home Forces, any airborne or seabor ...

PIAT
The Projector, Infantry, Anti Tank (PIAT) Mk I was a British man-portable anti-tank weapon developed during the Second World War. The PIAT was designed in 1942 in response to the British Army's need for a more effective infantry anti-tank weapon and entered service in 1943. The PIAT was based on the spigot mortar system, and projected (launched) a 2.5 pound (1.1 kg) shaped charge bomb using a cartridge in the tail of the projectile. It possessed an effective range of approximately in a direct fire anti-tank role, and in an indirect fire role. The PIAT had several advantages over other infantry anti-tank weapons of the period: it had greatly increased penetration power over the previous anti-tank rifles, it had no back-blast which might reveal the position of the user or accidentally injure friendly soldiers around the user, and it was simple in construction. However, the device also had some disadvantages: powerful recoil, a difficulty in cocking the weapon, and early pro ...

Axis Powers
The Axis powers, originally called the Rome–Berlin Axis and also Rome–Berlin–Tokyo Axis, was the military coalition which initiated World War II and fought against the Allies of World War II, Allies. Its principal members were Nazi Germany, Fascist Italy, Kingdom of Italy and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion. The Axis grew out of successive diplomatic efforts by Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the Italo-German protocol of 23 October 1936, protocol signed by Germany and Italy in October 1936, after which Italian leader Benito Mussolini declared that all other European countries would thereafter rotate on the Rome–Berlin axis, thus creating the term "Axis". The following November saw the ratification of the Anti-Comintern Pact, an anti-communis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
