M41 Vulcan

The M41 Light Anti-Aircraft Gun is a United Nations Space Command vehicle-mounted projectile machine gun.

The M41 LAAG is the standard armament for the M12 Warthog LRV. It is a three-barreled, electric-powered, linkless, drum-fed weapon. It fires 450 to 550 12.7x99mm armor penetrating rounds per minute. Turret traverse rate is 100 degrees per second and weapon elevation rate is 60 degrees per second. Recoil from sustained fire is prodigious and negatively impacts accuracy at long range.

It seems to be replaced by the AIE-486H Heavy Machine Gun in Halo 3.
