The prototype of heavy self-propelled gun ISU-122 (in Russian ИСУ-122) was built at ChKZ (Chelyabinskiy Kirovskiy Zavod, the Chelyabinsk Kirov Plant, Chelyabinsk, Russia) in December 1943. It shares the same chassis with ISU-152 self-propelled gun and differs only in armament. ISU-122 has the A-19S 121.92-mm gun as its main weapon instead of the ISU-152's ML-20S gun-howitzer. The towed versions of these guns had the same carriage 52-L-504A (Russian designation 52-Л-504А). So the installation of an A-19 instead of ML-20 was not a difficult task. After completing the ISU-152 prototype, ChKZ engineers mounted an A-19 on the ISU-152 chassis, designated "Object 242" — the first ISU-122 prototype. It was successfully tested, but not immediately launched into mass production.

The Heavy Tank M26 Pershing was an American heavy tank used during World War II and the Korean War. It was named after General John Pershing, who led the American Expeditionary Force in World War I.This heavy tank could stand up to about anything the German Panzer division had and went head to head with the German Tiger Tank.

Tiger II is the common name of a German heavy tank of the Second World War. The official German designation was Panzerkampfwagen VI Ausf. B and the tank also had the ordnance inventory designation SdKfz 182. It is also known under the informal name Königstiger (German: Bengal Tiger), often literally translated as King Tiger and by the British as Royal Tiger

The Universal Carrier, usually known as a Bren Gun Carrier (even when it was not carrying a Bren), was a small, tracked British-designed military vehicle, used widely by Allied forces during World War II. Universal Carriers were usually used for transporting personnel and equipment, mostly support weapons, or as machine gun platforms. With some 113,000 built in Great Britain and abroad, it was the most numerous armored fighting vehicle in history.

The Fiat-Ansaldo M13/40 was an Italian medium tank ("M" for Medio (medium) according to the Italian tank weight standards at the time: 13 tonnes was the scheduled weight and 1940 the initial year of production), designed to replace the Fiat L3, the Fiat L6/40 and the Fiat M11/39 in the Italian Army at the start of World War II. The design was influenced by the British Vickers 6-Ton and was based on the modified chassis of the earlier Fiat M11/39. Indeed, M11/39 production was cut short in order to get the M13/40 into production. Although designated a medium tank, the M13/40 was close to contemporary light tanks in armor and firepower.

The Iosif Stalin tank (or IS tank, named after the Soviet leader Joseph Stalin), was a heavy tank developed by the Soviet Union during World War II. The tanks in the series are also sometimes called JS or ИС tanks.The heavy tank was designed with thick armour to counter the German 88 mm guns, and sported a main gun that was capable of defeating the new German Tiger and Panther tanks. It was mainly a breakthrough tank, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 was put into service in April 1944, and was used as a spearhead in the Battle for Berlin by the Red Army in the final stage of the war.

The SdKfz 124 Wespe (German for wasp) or (Leichte Feldhaubitze 18 auf Fahrgestell Panzerkampfwagen II) was a German self-propelled artillery vehicle developed and used during the Second World War. It was based on the Panzer II tank.In 1940, during the Battle of France, it was apparent that the main tank of the German forces, the Panzer II, was unsuitable as a direct combat vehicle; though mechanically sound, it was both under-gunned and under-armoured. Thus, when the need arose for a self-propelled artillery vehicle, the Panzer II was a natural choice, removing the vehicles from front line service and extending their usable lifespan.The design for the Wespe was produced by Alkett, and was based on the Panzer II Ausf. F chassis. Production of the vehicles was carried out at various plants, mainly in Poland. The conversion process itself proved relatively simple, involving the replacement of the Panzer II turret with a 105 mm howitzer and gun-shield.The Wespe first saw combat in 1943 on the Eastern Front, and proved so successful that Hitler ordered all Panzer II production to be reserved for the Wespe alone, dropping other projects such as the Marder II. Rare, they were allocated to the armored artillery battalions (Panzerartillerie Abteilungen) of Panzer divisions along with heavier Hummel self-propelled guns.
