The BT-7 Tragedy: Why Did the "Fast Tank" Burn in June 1941?

The story of the Soviet BT-7 fast tank marks a journey from a daring engineering concept to the harsh realities of June 1941. In this video, we examine the design features of this machine, built on the chassis concept of American inventor J. Walter Christie. Discover how the unique wheel-and-track system worked, why the M-17 aircraft engine combined with light armor created high risks for the crew, and how the Deep Battle doctrine defined its tactical role. We analyze the combat history of the BT series, from Khalkhin Gol and the Winter War to the massive tank clash at Brody-Dubno. Explore Wehrmacht anti-tank tactics and learn how the lessons of the BT-7 paved the way for the development of the iconic T-34.
