The M247 General Purpose Machine Gun, also known as the Machine Gun, Caliber 7.62x51mm, or M247 is a lighter variant of the M247H Heavy Machine Gun. It is designed to fire smaller 7.62mm rounds from a stationary position. Despite this, the M247 GPMG can punch a hole through just about anything and, when mounted on its stationary base, functions as both an offensive and defensive support weapon. Besides turret and portable versions, the M247 GPMG is also found on the M312 Heavy Recovery Vehicle and can be mounted from the ceiling of the D77-TC Pelican's troop bay, while a version known as the M247T Medium Machine Gun is equipped on the M808B Main Battle Tank and M850 Main Battle Tank.
