The AIE-486H Heavy Machine Gun (abbreviated AIE-486H HMG or simply HMG), more commonly referred to as the Heavy Machine Gun Turret, is a UNSC machine gun effective against infantry and light vehicles .

The AIE-486H Heavy Machine Gun is a standard Gatling-style medium machine gun, used by the UNSC for offensive and defensive purposes. It is also more powerful than the UNSC's stationary turret, the M247 GP Machine Gun.

For defensive purposes, it can be mounted on a tripod, but when used for an assault, it can be irreversibly and quickly detached from its mount. When dismounted, the weapon has a limited ammunition capacity of 200 rounds and takes about a second to "spin up" before reaching its highest rate of fire. Pulling the trigger once will cause the gun to fire a maximum of two rounds at a moderate rate; holding it down builds up the rate of fire to a higher rate.

The gun's muzzle climbs slowly during sustained fire (like the M7 Caseless Submachine Gun). Its recoil is lessened by the gun's weight, but this also decreases the user's walking speed and overall mobility. Unlike other heavy machine guns in the Halo series, the AIE-486H does not overheat with continuous fire. This is a realistic portrayal, as having three barrels on the gun disperses the heat equally among them, allowing the gun to remain cool and continue functioning for long periods of time.
