Galeria de fotos em um tanque rápido BT-7, projetado no início dos anos trinta, tanques rápidos BT desempenhou um papel importante no desenvolvimento da força blindada soviética. Foram os primeiros modelos de tanques disponíveis em grande número que permitiram o desenvolvimento de doutrinas mecanizadas. Embora essas doutrinas tenham sido desacreditadas e esquecidas pouco antes do início da invasão alemã, elas abriram caminho para doutrinas posteriores que usaram o descendente do BT, o 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.
