AIE-486H machine gun

The AIE-486H Heavy Machine Gun (abbreviated AIE-486H HMG), more commonly referred to as the Heavy Machine Gun Turret, is a United Nations Space Command ground weapon effective against infantry and vehicles. It fires armor piercing rounds at a high rate of fire. When detached it provides a portable high-powered machine gun.

Overview
The AIE-486H Heavy Machine Gun is a standard Gatling-style heavy weapon in use by the UNSC for offensive and defensive purposes. It is more powerful than the UNSC's M247 GP Machine Gun turret. For defensive purposes it can be mounted on a tripod but when used for assault it can be detached from its tripod by a SPARTAN-II's or Elite's brute force. In its unmounted form, while mobile, it has a limited ammunition capacity of 200 rounds and takes about a second to "spin up" before reaching its highest rate of fire. When the player picks up this weapon, they still keep their two other weapons. However, they must drop the HMG before using their other weapons. The mounted turret is capable of fully automatic fire and has extreme defensive value as a mass generator of suppressive fire. However, the user's rate of elevation is low, there is a maximum angle of fire, and the user is stationary, exposed, and unable to react quickly to close-range scenarios. It has an infinite ammo capacity while stationary.

Once on it, the player can detach the turret and use it as a portable weapon (done by pressing B). Once detached, the player will appear in a third-person view. The player also becomes slower due to the weapon's weight and the accuracy is decreased, so they're very easy for grenade sticks. While wielding the gun in its standalone form (unmounted), the player cannot run or turn around quickly, nor can he/she melee, use grenades, equipment, or binoculars. When standing in one point the player can aim slightly to either side before the Spartan or Elite adjusts their feet.

Pulling the trigger once will cause the gun to fire two rounds at a moderate rate; holding it down builds up the rate of fire to a higher rate. The gun slowly climbs during automatic fire like the SMG, but its recoil is lessened by the gun's weight. Unlike most miniguns in other games, the gun cannot overheat, which is more realistic, as one of the designs of a mini-gun is to have multiple barrels, so that one barrel does not overheat due to the fire rate. Having three barrels disperses the heat equally to all three barrels.

Trivia

 * The AIE-486H Heavy Machine Gun, belonging to the Halo 3 exclusive class of weapons known as "Support Weapons," is one of the four third-person view weapons. The other weapons are the M7057 Defoliant Projector, the Missile Pod and the Plasma Cannon.
 * When hefting a support weapon, you do not lose the 2 weapons you were carrying. Your primary weapon will be shunted to the secondary slot, while your previously secondary weapon does not appear on the HUD or on your body. Instead, it is kept somewhere unseen, and goes into a "tertiary" slot.
 * Like the M41 LAAG, the AIE-486H bears a striking resemblance to the GAU-19/A machine gun used by the United States military. The GAU-19 and AIE-486H both share the same distinctive suppressor.
 * The AIE-486H appeared in early footage of pre-Xbox Halo as the minigun.
 * During Forge matches, the mounted AIE-486H can be picked up, moved, and rotated, even while another player is using the turret, effectively allowing the player to be a "flying turret o' doom". If the other player rips the turret from the base while this is happening, the player will duplicate the turret. This can be used to arm an entire team with turrets. These traits also apply to plasma turrets.
 * The HMG can carry more than 200 rounds when detached, through a glitch. See Extra Ammo in HMG Glitch
 * It seems to be much the same as Vietnam gunships.
 * It is unusable when mounted in the Pelican.
 * It climbs much like the SMG.
 * Brutes will occasionally use a Heavy Machine Gun against players and humans.
