Description	Album de 105 photos walk-around du char rapide «BT-7»

Galerie photo sur un char rapide BT-7, Conçus au début des années trente, les chars rapides BT ont joué un rôle majeur dans le développement de la force blindée soviétique. Ils ont constitué les premiers modèles de chars disponibles en grand nombre qui permirent de développer des doctrines mécanisées. Même si ces doctrines furent déconsidérées et oubliées juste avant le début de l’invasion allemande, elles ouvrirent la voie à celles, ultérieures, qui utilisèrent le descendant des BT, le 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.
