KV-1, 262nd Heavy Tank Regiment, 7th Guards Army. The KV-1 shocked the invading German forces in the summer of 1941, but over the next two years, the Wehrmacht fielded improved antitank weapons better able to penetrate its armor. The inability of the heavier and less speedy and agile KVs to keep up with the T-34s led to them being formed into separate heavy breakthrough tank regiments for infantry support. The KV-1 portrayed participated in the Voronezh Front’s defensive operations against the III Panzer Korps and was disabled during the subsequent Soviet Operation Rumyantsev offensive against Belgorod and Kharkov. The tank carries no tactical markings, but the crew has added “Bagration,” a patriotic reference to a Russian general killed during the Battle of Borodino in 1812, to the side of the turret.
