The BT-7 was the last of the BT series of Soviet cavalry tanks that were produced in large numbers between 1935 and 1940. They were lightly armoured, but reasonably well-armed for their time, and had much better mobility than other contemporary tank designs. The successor of the BT-7 Tank would be the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and medium tanks then in service
Jagdpanzer Ferdinand at Kursk Ferdinands first saw combat in the Battle of Kursk, where eighty-nine were committed, the most concentrated use of the vehicle. The Ferdinand was optimized for destroying Soviet T-34 tanks and 76.2 mm anti-tank guns from behind the front lines with its 88mm Pak43/2 L/71 at a range of over 3 kilometres, a role which it performed well.
