The GAZ-AAA (4M) quad 7.62mm Maxim anti-aircraft truck was a Self-propelled anti-aircraft weapon developed by the Soviet Union in 1938, [1] based on the GAZ-AAA truck platform.
In 1928, Fedor Tokarev developed a quad mount for the 7.62×54mmR PM M1910 machine gun for use as a light anti-aircraft weapon, which was adopted in 1938 [2] as the 7.62mm M.1931 4M ZPU. [3] The 4M ZPU was mounted on a GAZ-AAA truck to create a mobile AA weapon.
Later versions of the anti-aircraft truck equipped the 12.7×108mm DShK machine gun. [1] [4]
The quad-Maxim mount was also used on the 4x2 GAZ-MM and GAZ-60 half-tracks. [5]
