The ISU-122 was a self-propelled anti-tank gun fielded by the Soviet Union during World War II. Produced by Chelyabinsk Kirvo Plant, it entered service with the Red Army in April 1944 and was phased at the end of the 1950s. It was a powerful, front line weapon that was always in the vanguard of the Soviet advances through Germany towards Berlin. More than 2,000 ISU-122s were made, about 600 of which were equipped with a semi-automatic breech block. This self-propelled, assault/anti-tank gun also saw combat action in Korea, used by the North Korean and Chinese Armies.
The ISU-122 consisted of one 122mm A-19 gun, mounted on the KV-2 heavy tank’s chassis. The vehicle carried 30 rounds and a crew of 5 men, who were protected by 90-mm-thick steel armor. This gun fired high-velocity projectile and could destroy a Panzer IV tank from a distance of 2,000 m; it was also used to destroy enemy bunkers and to provide indirect fire support. It was powered by one 520-hp, V-12 diesel engine.
