The AA machine Gun is the main anti-aircraft weapon from the Regular Army, that appeared in Metal Slug and 3.


Used first by the Regular Marines, and later by the Regular Infantry, it is a tipic .50 mm machine gun, firing light bullets. Its high rate of fire makes it a formidable machine gun. The blue design is used by the marines and the silver one by the Infantry. This can be used by the player if found, and can be used to deal with paratroopers, regular infantry, and especially fighters.
