Summary
The Warthog's M41 LAAG AA gun 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 is the standard equipment on the M12 LRV Warthog.
