Comparing: T1E6 vs. Tetrarch vs. Vickers Mk. E Type B

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.

Developed in 1936 by the Vickers-Armstrong company, with a total of 177 vehicles in two basic modifications the Tetrarch Mk I and the Tetrarch Mk ICS manufactured from 1941 through 1942. In 1942 twenty vehicles were delivered to the U.S.S.R. under Lend-Lease, of which 19 fought on the Eastern Front until October 1943.

Developed in 1928 by J. V. Carden and V. Loyd. The vehicle never entered service in Great Britain. However, it was exported to other countries, including China. In 1937, twenty vehicles of this type fought against Japanese troops at Shanghai. Soviet Vickers-based T-26 vehicles were also exported to China, and 82 vehicles of that type were deployed in South China and Birma in 1941–1942.
