T-38 tank
The T-38 amphibious scout tank was a Soviet amphibious and reconnaissance light tank that saw service in World War II. Developed as a modernized version of the earlier T-37A light tank, which had roots in the British Vickers amphibious tank, it also took design ideas from the French AMR 33, the T-38 proved to be only a moderate improvement over its predecessor. Its relative light weight allowed Soviet aircraft to strap the tank on bomber fuselages, and deliver them to front lines.
