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.

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.
