Mark IV tank The Mark IV (pronounced "Mark Four") was a British tank of World War I. Introduced in 1917, it benefited from significant developments on the first British tank (the intervening designs being small batches used for training). The major improvements were in armour, the re-siting of the fuel tank, and easier transportation. A total of 1,220 were built: 420 "Males", 595 "Females" and 205 Tank Tenders (unarmed vehicles used to carry supplies), which made it the most numerous British tank of the War.

Raketenjagdpanzer 1 The Raketenjagdpanzer 1 is an anti-tank guided missile-armed tank destroyer (the first such vehicle in service with the West German Armed Forces) that entered service in 1961. It was built on the chassis of the Hispano-Suiza HS-30, which was also used on the Schützenpanzer SPz 12-3, and armed with twin French SS.11 antitank guided missile launchers. Only one of the missile launchers is visible from the outside at any time, however, as the other is retracted into the hull to be reloaded when the first is ready to fire.

Winchester Hotchkiss The Winchester Hotchkiss was a bolt-action repeating rifle patented by Benjamin B. Hotchkiss in 1876 and produced by the Winchester Repeating Arms Company and Springfield Armory from 1878. The Hotchkiss like most early bolt-actions had a single rear locking lug integral with the bolt handle, but was unique in feeding multiple rounds from a tubular buttstock magazine similar to the Spencer rifle. The .45-70 Hotchkiss was acquired in limited numbers by the US Navy as the M1879, and (in a slightly modified version) by the US Army and several state militias as the M1883, making it the first center-fire bolt-action repeater to be adopted by any major military (the distinction of first bolt-action repeating rifle to be a issued in great numbers as a standard military arm was the Swiss Vetterli 1869, which utilized very large rim-fire metallic cartridges).

Vorne The Vorne, or VK 4502 (P) Ausf. c, is a tank designed by Ferdinand Porsche to compete with Henschel's design, alongside the Ausf. B version of the tank. The Henschel design was selected for production, but never reached the prototype phase. Porsche was confident that his design would win a contract for production and so he ordered Krupp to produce 50 turrets for the tank. These turrets were used on the first Tiger II's, which were supposed to be armed with a KwK L/71 gun, like its Henschel Counterpart.

Sherman Firefly The Sherman Firefly was a tank used by the United Kingdom and some Commonwealth and Allied armoured formations in the Second World War. It was based on the US M4 Sherman, but fitted with the powerful 3-inch (76.2 mm) calibre British 17-pounder anti-tank gun as its main weapon. Originally conceived as a stopgap until future British tank designs came into service, the Sherman Firefly became the most common vehicle mounting the 17-pounder in the war.

Vickers machine gun The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The machine gun typically required a six to eight-man team to operate: one fired, one fed the ammunition, the rest helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft.

M2 Medium Tank The M2 Medium Tank, officially Medium Tank, M2, was a United States Army medium tank that was first produced in 1939 by the Rock Island Arsenal, just prior to the commencement of the Second World War in Europe. Production was 18 M2 tanks, and 94 slightly improved M2A1 tanks, for a total of 112. Events in Western Europe rapidly demonstrated that the M2 was obsolete, and it was never used overseas in combat; it was, however, used for training purposes throughout the war.

M10 tank destroyer The M10 tank destroyer was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942, being delivered in April of that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1943 as the 3-inch Gun Motor Carriage M10. It mounted a 3-inch (76.2 mm) Gun M7 in a rotating turret on a modified M4A2 Sherman tank chassis. An alternate model, the M10A1, which used the chassis of an M4A3 Sherman tank, was also produced. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 1943, respectively.

Saint-Chamond (tank) The Saint-Chamond, named after the commune of Saint-Chamond, was the second French heavy tank of the First World War, with 400 manufactured from April 1917 to July 1918. Although not a tank by the present-day definition, it is generally accepted and described as such in accounts of early tank development. Born of the commercial rivalry existing with the makers of the Schneider CA1 tank, the Saint-Chamond was an underpowered and fundamentally inadequate design. Its principal weakness was the Holt "caterpillar" tracks. They were much too short in relation to the vehicle's length and heavy weight (23 tons). Later models attempted to rectify some of the tank's original flaws by installing wider and stronger track shoes, thicker frontal armour and the more effective 75mm Mle 1897 field gun. Altogether 400 Saint-Chamond tanks were built including 48 unarmed caisson tanks. The Saint-Chamond tanks remained engaged in various actions until October 1918, belatedly becoming more effective since combat had moved out of the trenches and onto open ground. Eventually the Saint-Chamond tanks were scheduled to be entirely replaced by imported British heavy tanks.

Albatross-class brig-sloop The "Albatross" class were built as a class of eight 18-gun brig-sloops for the Royal Navy. They were originally to have carried sixteen 6-pounder carriage guns, but on 22 April 1795 it was instructed that they should be armed with sixteen 32-pounder carronades, although two of the 6-pounders were retained as chase guns in the bows. Consequently, they were classed as 18-gun sloops. However, in service it was found that this armament proved too heavy for these vessels, and so in most vessels the 32-pounder carronades were replaced by 24-pounder ones.

Main battle tank A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the armor-protected direct fire and maneuver role of many modern armies. Cold War-era development of more powerful engines, better suspension systems and lightweight composite armour allowed a tank to have the firepower of a super-heavy tank, armor protection of a heavy tank, and mobility of a light tank all in a package with the weight of a medium tank. Through the 1960s, the MBT replaced almost all other tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles.
