The M62 light machine gun was a magazine-fed, air-cooled, gas-operated, selective fire infantry weapon used by the United Nations Space Command during the Swarm War. The M62 was designed to give soldiers operating within a squad additional range and volume of fire without drastically increasing weight. The M62 utilised the 7.62x51mm NATO round, a well-balanced round in comparison to alternative calibres, its accuracy and rate of fire, combined with negligible recoil, making it well suited for use in the M62. The gun provided infantry squads with the heavy volume of fire of a machine gun combined with accuracy and portability approaching that of a rifle.
