The DShK 1938 (ДШК, for Дегтярёва-Шпагина Крупнокалиберный, Degtyaryova-Shpagina Krupnokaliberny, Degtyaryov-Shpagin high-caliber in English), colloquially known as the Dashka or Dushka, is a Soviet heavy machine gun which uses the 12.7x108mm cartridge. It has been used since World War II, and has been used by many other countries ever since.
The DShK is based on the older DK machine gun. The weapon is gas-operated, with reload flaps actuating the action. The weapon is put into battery by pulling a massive charging handle located at the bottom of the weapon. The weapon is fed by massive disintegrating 50-round metal belts.
The DShK has been used frequently by mostly third-world countries in wars due to its massive stopping power, due to its high-caliber round. The weapon was purported to have destroyed 40 cars in a day during the Syrian Civil War in 2012, and also caused a helicopter to crash-land during The Troubles in Norther Ireland in 1987 after 15 shots from 2 DShKs hit the helicopter.
