Comparing: BT-7 artillery vs. M22 Locust

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.

Initially designed for airborne operations, the vehicle was never used as such by the U.S.A. during World War II. In the absence of a good air delivery system, the Ordnance Department became less enthusiastic about any further development.
