Light anti-aircraft gun
Electrically-powered, Linkless, belt-feed
500 rpm 
The M41 LAAG is a triple-barreled, electric-powered, linkless, belt-fed weapon, capable of firing 500 12.7×99mm armor-piercing 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.
Its extended variant, the M41 Extended Light Anti-Aircraft Gun, is a four-barreled machine gun capable of firing depleted uranium containing pressurized atmosphere. This variant is mounted on the aft of the OF92/EVA Booster Frame.
- Main article: 12.7×99mm Armor-Piercing
The 12.7×99mm rounds is capable of exerting upwards of five times as much damage as the 7.62×51mm rounds used in the MA5 series of assault rifles, and the M41 is a relatively accurate example of its power compared to the smaller 7.62mm round.[note 1]
- Before this weapon was named the M41 Vulcan, the name for this weapon was the "M1100-Mk II Vehicle Mounted Support Weapon".
- This weapon bears a close resemblance to the GAU-19/A machine gun used by the United States military. In addition to other superficial similarities, both are triple-barreled Gatling-style machine guns, and both weapons also fire the 12.7×99 mm round.
- Vulcan is the Roman name for the Greek god Hephaestus, God of fire and forgery, and the name of several current-day high-caliber Gatling-style guns.
- The armor plating can be shot or beaten off in Halo 2, Halo 3, and Halo: Reach.
- Halo 3 MythBusters proved that one can perform a Superbounce in Halo 3 using a detached Warthog turret from a destroyed Warthog.
- A stationary version of the M41 LAAG, as well as the M68 Gauss Cannon, appears in Halo 3: ODST.
- In Halo Wars trailers, renders, and cutscenes, the M41 is shown with four barrels. It is unknown if this is a graphical change or a different weapon altogether.
- In Halo: Reach, the M41 LAAG takes a few seconds to spin up, whereas in previous games the spin-up was instantaneous. Also, like all other turret weapons in the game, the M41 LAAG will overheat after continuous fire. This was implemented as a balancing change, preventing the "turret spam" prevalent in previous games.
- In Halo 2: Anniversary, the M41 LAAG is replaced by M46 Light Anti-Aircraft Gun, indicating that the two weapons saw combined service during the late stages of the Human-Covenant War.
- In Halo: Spartan Assault, the stationary turret is the M41 LAAG. The weapon can overheat with excessive continuous fire, forcing a cooldown period of approximately 5 seconds before it is able to fire again. Additionally, the weapon has a health bar; if the this health bar completely depletes, the weapon is destroyed. If the player is using the turret when it is destroyed, they will be instantly killed. In the sequel Halo: Spartan Strike the weapon no longer overheats and the player is not killed if it is destroyed while they are using it.
The 12.7×99mm Armor-Piercing Round the M41 fires from The Art of Halo 3.
