Galerie photo sur un char rapide BT-7, Conçus au début des années trente, les chars rapides BT spillede en stor rolle i udviklingen af den sovjetiske pansrede styrke. De var de første kampvognsmodeller, der var tilgængelige i stort antal, og som tillod udviklingen af mekaniserede doktriner. Selv om disse doktriner blev miskrediteret og glemt lige før starten på den tyske invasion, banede de vejen for senere doktriner, der brugte BT's efterkommer, T-34.

Key Characteristic: Convertible Drive

The BT-7 used the Christie Suspension which allowed the crew to remove the tracks and drive the tank directly on its large road wheels when traveling on roads. This capability was designed to reduce wear on the tracks and achieve extremely high speeds.

Note on Vulnerability The tank’s light armor and use of a gasoline engine made it highly vulnerable to enemy fire, a factor that contributed to significant losses early in World War II.
