The M85 is a heavy machine gun firing .50 BMG ammunition that was used primarily for turreted applications in armored fighting vehicles. It was intended to replace the venerable M2 machine gun with a smaller and much lighter weapon, suitable for use inside fighting vehicles, as opposed to only on external mounts. It is used on the M60 series of tanks and the LVTP-7 amphibious landing vehicle.
