America's Army/RPK Automatic Rifle

The RPK Automatic Rifle is the Opfor equivalent to the M249 SAW, except with 75x4 bullets initially.

The RPK in America's Army is probably either the original RPK with a drum magazine (http://world.guns.ru/machine/mg15-e.htm) or the RPK-74 (http://world.guns.ru/machine/mg16-e.htm).
