1.45 cm ZPU-4: Soviet towed anti-aircraft gun
The first dedicated Soviet mount for anti-aircraft machine guns was developed around 1928 by Fedor Tokarev and was adopted for service in 1931. It was a base for mounting up to four 7.62 mm PM M1910 (Russian Maxim) guns.
This was also called a ZPU, although the name М-4 was also assigned to it. It served the Soviet armed forces in all major conflicts until 1945. 12.7 mm DShK 1938 was used an anti-aircraft weapon it was mounted on pintle and tripod mounts, and on a triple mount on the GAZ-AA truck.
Late in the war, it was mounted on the cupolas of IS-2 tanks and ISU-152 self-propelled guns. As an infantry heavy support weapon it used a two-wheeled trolley which unfolded into a tripod for anti-aircraft use.
