The Browning M2 .50 caliber machine gun is an automatic, belt-fed, recoil operated, air-cooled, crew-operated machine gun. The system is highly effective against light armored vehicles, low- and slow-flying aircraft, boats and enemy personnel. The M2 is crew transportable with limited amounts of ammunition over short distances. The gun is capable of being modified to fire in single-shot mode, as well as automatic fire. It may be mounted on ground mounts and vehicles as an anti-personnel and anti-aircraft weapon. By repositioning some of the component parts, ammunition may be fed from either the left or right side. A disintegrating metallic link belt is used to feed the ammunition into the weapon.
