Comparing: BT-7 artillery vs. AMX 38

In 1934–1935 the design bureau of the Kharkiv Locomotive Factory developed this artillery modification of the BT-7. The new elliptical turret was equipped with the 76.2-mm CT-28 gun. In addition, some vehicles received new radio stations. A total of 155 artillery BT-7s were manufactured. The vehicles saw combat on the Karelian Isthmus, in Manchuria, and during the first period of the Great Patriotic War.

Developed in 1937 by the AMX company on the basis of the Renault R-40. The vehicle had a larger turret than comparable vehicles and was equipped with a diesel engine. By 1940 two vehicles were ready for trials.
