|The U.S. Army is in the early stages of beginning to draft requirements for a new externally-mounted weapon to replace both the M2 .50-cal machine gun and the Mk19 grenade launcher. The planning is to engineer a weapon that has the attack and fire ability of a .50-Cal along with an explosive "area weapon" effect of a grenade launcher.|
Meanwhile the Army is creating a new, lightweight version of its iconic .50-cal machine gun. A new addition to the weapon is called a Mounted Gun Optic, or MMO. It is basically an optic or direct view optic which will have some type of laser crosshair.
