Comparing: T1E6 vs. Pz.Kpfw. 38H 735 (f) vs. BT-2

Experimental vehicles T1E4 through T1E6 were heavily influenced by the British Vickers E. The first prototype was manufactured by the Cunningham corporation in 1931. After trials in 1932, an upgraded variant was built. However, a different experimental tank, the T2, was preferred.

In May 1940 the French Army had more than 800 vehicles of this type, most of which were captured by the German forces. They were widely used by the Wehrmacht to supplement existing armor.

Developed on the basis of the Christie tank M1931. Produced at the Kharkiv Komintern Locomotive Factory (KhPZ), with 650 BT-2 tanks and 1,884 BT-5 tanks manufactured from 1932 through 1935.
