DShKM
The DShK (Дегтярёва-Шпагина Крупнокалиберный), often nicknamed Dushka, is a Soviet heavy machine-gun firing 12.7x108mm commonly mounted on vehicles or on a tripod. It entered service in the USSR in 1938, making its combat debut in WW2. After the war, the DShK would get a new muzzle brake and improvements to its feed mechanism, receiving the designation DShKM. Like many Soviet weapons, it was exported globally, leading to many countries making local copies and its widespread appearances in many conflicts around the world.
