DD tankDD or Duplex Drive tanks, nicknamed "Donald Duck tanks", were a type of amphibious swimming tank developed by the British during the Second World War. The phrase is mostly used for the Duplex Drive variant of the M4 Sherman medium tank, that was used by the Western Allies during and after the Normandy Landings in June 1944. DD tanks worked by erecting a canvas 'flotation screen' around the tank, which enabled it to float in water. DD tanks would use propellers to move forward through water, then lower the flotation screens once they had reached land and fight as an ordinary tank.
M2 light tankThe M2 light tank, officially Light Tank, M2, was an American light tank of the interwar period which saw limited service during World War II. The most common model, the M2A4, was equipped with one M5 gun and five .30 cal M1919 Browning machine guns. It was originally developed from the prototype T2 light tank built by the Rock Island Arsenal, which had a Vickers-type leaf spring suspension. The suspension was replaced by the superior vertical volute system in the T2E1 series of 1935.
Light tankA light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently.
Tanks in the German ArmyThis article deals with the tanks (Panzer) serving in the German Army (Deutsches Heer) throughout history, such as the World War I tanks of the Imperial German Army, the interwar and World War II tanks of the Nazi German Wehrmacht, the Cold War tanks of the West German and East German Armies, all the way to the present day tanks of the Bundeswehr. The development of tanks in World War I began as an attempt to break the stalemate which trench warfare had brought to the Western Front.
Flame tankA flame tank is a type of tank equipped with a flamethrower, most commonly used to supplement combined arms attacks against fortifications, confined spaces, or other obstacles. The type only reached significant use in the Second World War, during which the United States, Soviet Union, Germany, Italy, Japan, and the United Kingdom (including members of the British Commonwealth) all produced flamethrower-equipped tanks. A number of production methods were used.
Tanks in World War IThe development of tanks in World War I was a response to the stalemate that developed on the Western Front. Although vehicles that incorporated the basic principles of the tank (armour, firepower, and all-terrain mobility) had been projected in the decade or so before the War, it was the alarmingly heavy casualties of the start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead.
Tanks in the Cold WarTank development both evolved considerably from World War II and played a key role during the Cold War (1945–1990). The period pitted the nations of the Eastern Bloc (organized under the Warsaw Pact in 1955) and the North Atlantic Treaty Organization (NATO (since 1949) against each other. After World War II, tank design budgets were cut and engineering staff was often scattered. Many war planners believed that with the advent of nuclear weapons the tank was obsolete, given that a tactical nuclear weapon could destroy any brigade or regiment, whether it was armoured or not.
Infantry tankThe infantry tank was a concept developed by the United Kingdom and France in the years leading up to World War II. Infantry tanks were designed to support infantrymen in an attack. To achieve this, the vehicles were generally heavily armoured to allow them to operate in close concert with infantry even under heavy fire. The extra armour came at the expense of speed, which was not an issue when supporting relatively slow-moving foot soldiers.
Cruiser tankThe cruiser tank (sometimes called cavalry tank or fast tank) was a British tank concept of the interwar period for tanks designed as modernised armoured and mechanised cavalry, as distinguished from infantry tanks. Cruiser tanks were developed after medium tank designs of the 1930s failed to satisfy the Royal Armoured Corps. The cruiser tank concept was conceived by Giffard Le Quesne Martel, who preferred many small light tanks to swarm an opponent, instead of a few expensive and unsatisfactory medium tanks.
