After August 1944, production of the Tiger I was phased out in favour of the Tiger II.

Tank destroyer battalion (United States) The tank destroyer battalion was a type of unit used by the United States Army during World War II. The unit was organized in one of two different forms—a towed battalion equipped with anti-tank guns, or a self-propelled battalion equipped with Self-propelled guns. The tank destroyers were formed in response to the German use of massed formations of armored units early in WW2. The tank destroyer concept envisioned the battalions acting as independent units that would respond at high speed to enemy tank attacks. In this role they would be attached to divisions or corps. In practice, they were usually attached to infantry divisions. Over one hundred battalions were formed, of which more than half saw combat service. The force was disbanded shortly after the end of the war when the concept had been shown to be unsound.

Semovente da 47/32 The Semovente L. 40 da 47/32 was an Italian self-propelled gun built during World War II. It was created by mounting a Cannone da 47/32 anti-tank gun in an open-topped, box-like superstructure on a L 6/40 light tank chassis. Some were built as command tanks with a radio installed instead of the main gun. An 8 mm machine gun disguised as the 47 mm main gun was used on these versions to make them look like a regular Semovente 47/32s. About 300 Semoventi da 47/32 were built from 1941 onward. The Semovente da 47/32 was the most heavily armed Italian armoured fighting vehicle used on the Eastern Front.

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.

Ordnance QF 17-pounder The Ordnance Quick-Firing 17-pounder (or just 17-pdr) was a 76.2 mm (3 inch) gun developed by the United Kingdom during World War II. It was used as an anti-tank gun on its own carriage, as well as equipping a number of British tanks. It was the most effective anti-tank gun of the war fielded by the Western Allies (that is, excluding the Soviet Union). Used with the APDS shot, it was capable of defeating all but the thickest armour on German tanks. It was used to 'up-gun' some foreign-built vehicles in British service, notably to produce the Sherman Firefly variant of the US M4 Sherman tank, giving British tank units the ability to hold their own against their German counterparts. In the anti-tank role, it was replaced after the war by the 120 mm BAT recoilless rifle. As a tank gun, it was succeeded by the 84 mm 20 pounder.
