The 37mm Gun M1 was an anti-aircraft autocannon developed in the United States. It was used by the US Army in World War II.
In addition to the towed variant, the gun was mounted, with two M2 machine guns, on M2 / M3 halftrack, resulting in the T28 / T28E1 / M15 / M15A1 series of multiple gun motor carriages.
