In early January, the Corps announced it plans to invest up to $10 million in polymer-cased .50 caliber ammo to test in the 'Ma Deuce' machine gun, a potent weapon used by both Army and Marine mounted combat units.
The Army's role in the Joint Lightweight Ammunition Integrated Product Team is to find a lightweight-cased replacement for brass-cased 7.62 mm, the caliber used in Army and Marine M240 machine guns and some sniper weapons. The ultimate goal is to replace brass-cased ammo for all 7.62mm ammo in the Army.
