Summary


The M12 Warthog LRV's M41 LAAG 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.

In Halo 3
In the recent Halo 3 ViDoc: Is Quisnam Protero Damno!, a blue Spartan wielding what seems to be the M41 chain gun can be seen at 0:23-0:24 of the trailer. However, close inspection revels that this gun is different, and Frank O'Connor recently seemed to confirm that it is not the M41 in a Bungie Weekly Update, commenting, "... [those viewing the ViDoc saw] a new weapon. I saw it referred to as the 'chain gun' but I ain't talking. Although I will tell you that no, you can't pull the chaingun off the back of a Hog."

This seems to preclude its being the M41, but bear in mind that the Weekly Updates are often designed to conceal the truth. Merely because it has been confirmed that you cannot pull the chaingun off the back of a Hog does not mean that the "chain-gun" is not, in fact, the M41. It might work in the same manner as the Sentinel Beam, which can only be taken from the wreckage of Sentinels: only once the Warthog is destroyed can the gun be salvaged. That would make the Warthog still important even after being destroyed, as then any surviving crew would at the very least give the enemy hell until the battery is depleted. However, in the same Vidoc, when the warthog got destroyed by the trip mine, the turret is still on the warthog (this could be explained by the two scenes being from different versions, or the Chain Gun being a separate weapon entirely).
