From Marine Corps Times:

The commandant of the Marine Corps wants to vastly expand the fielding of infantry automatic rifles by putting them in the hands of nearly every “0311” rifleman.

“If we decide to put IARs throughout the rifle squads, we would not arm the squad leader with it, nor the platoon sergeant and platoon commander. Just the 0311 infantry Marines in the rifle squad,” he said.

Beyond the 0311 riflemen, Neller may also consider IARs for ­combat engineers and light armored ­reconnaissance battalion scouts, a Marine official said.
