M751 Heavy Machine Gun

Based on the M744 GPMG, the M751 is a .50 caliber heavy machine gun adopted by the UNSC Defense Force to replace the M247 General Purpose Machine Gun. In a portable format, designated the M751A, it is used with a deployable bipod for heavy infantry support. The M751B is the most common variant, using a universal mount for vehicle mounts and tripod mounts alike. A final variant, the M751C, is mounted as a coaxial weapon on a tank.
