The KV-2 was a heavy tank used by the Soviet Union during World War II. It was one of the largest and heaviest tanks of its time, and its thick armor made it difficult to penetrate.During the early stages of Operation Barbarossa, the German invasion of the Soviet Union, many KV-2 tanks were destroyed or disabled. However, some were captured by German forces and later used by the Germans against the Soviets.One notable example of a KV-2 tank captured by the Germans was the "Bärentöter" ("Bear Killer"), which was captured by the 6th Panzer Division during the Battle of Rostov in November 1941. The tank was repaired and used by the Germans until it was destroyed in combat in 1943.Overall, the Germans captured relatively few KV-2 tanks during the war, and their use of these tanks was limited due to logistical and technical difficulties.
