The M2HB has been in service with the U.S. Military and the armed forces of over 20 nations and is the world standard in heavy machine guns. It is a recoil operated, air-cooled, disintegrating link belt-fed machine gun, capable of both sustained automatic and accurate single shot fire. Ammunition may be fed from either the left or the right side of the gun, making it suitable for use by both infantry and in armoured vehicles. The M2HB is the logical choice to fill the gap between personal weapons and the larger, more complex and costly automatic cannons.
