The M42 40 mm Self-Propelled Anti-Aircraft Gun, or "Duster," is an American armored light air-defense gun built for the United States Army from 1952 until December 1960, in service until 1988. Production of this vehicle was performed by the tank division of the General Motors Corporation. It used components from the M41 light tank and was constructed of all-welded steel.

The M41 Walker Bulldog, officially 76-mm gun tank M41, was an American light tank developed for armed reconnaissance purposes. It was produced by Cadillac between 1951 and 1954 and marketed successfully to the United States Army as a replacement for its aging fleet of World War II-vintage M24 Chaffee tanks. Although engineered as a reconnaissance vehicle, the M41's weight and armament also made it effective in the close infantry support role and for rapid airborne deployments. Upon entering US service, all M41s received the designation Little Bulldog and subsequently, Walker Bulldog after the late General Walton Walker, who was killed in a Jeep accident in 1950. The M41 was the first postwar American light tank to see worldwide service, and was exported in considerable numbers by the United States, particularly to Asia.
