Part 1 of the two-part tour of the M56 Self-Propelled Anti-Tank gun.
The M56 SPG was intended to support airborne units as a light tank destroyer that could be transported by cargo planes or inserted by parachute or glider. The vehicle was mass-produced from 1953 through 1959, but it was not popular and was soon replaced by the Sheridan light tank. The Scorpion was occasionally used to provide artillery support in Vietnam.
