Medium Caliber Ammunition (MCA) includes 20 mm, 25 mm, 30 mm, and 40 mm Armor-Piercing (AP), High-Explosive (HE), smoke, illumination, training, and antipersonnel cartridges with the capability to defeat light armor, materiel, and personnel targets. These munitions provide overwhelming lethality in MCA and point- and area-target engagement via medium handheld, crew-served, ground platform and aircraft mounted weapons. 


Standard ammunition provides the Warfighter with the necessary lethality needed to defeat the enemy. Specialty cannon caliber and 40 mm cartridges provide unique capabilities for the Warfighter (e.g., airburst, illumination).
