Video: Russian RPD

The RPD is a gas-operated, belt-fed light machine-gun developed by the Russians during World War II, but never saw full production or service before that war ended. It did, however, see extensive action during the war in Vietnam, as derivatives of it were produced by several other countries, including China, Poland, Korea and Egypt. It was used by the Viet Cong and the north Vietnamese and was considered an extremely effective weapon, and could be called the pro-generator of the Squad Automatic Weapon (SAW).
