Support weapon

Support Weapons are a class of heavy weapons. They can be only used in Halo 3 and Halo 3:ODST, but also appear in Halo Wars.

These weapons are much larger than the standard handheld weapons, and require two hands to heft. Consequentially, players move more slowly while holding them, and cannot throw grenades or melee opponents while holding the weapons, thus they become very vulnerable to enemy grenades and vehicles, since they almost can't be dodged.

With the exception of the Flamethrower, support weapons are generally weapons that were originally designed to be fired from stationary mounts, but have been ripped off of their bases and carried around. Thus while they have limitless ammunition while in their mounts, once removed and carried the ammo they have becomes limited. Also, the accuracy of the turret can become more of a problem, being handheld of course.

Trivia

 * The Flamethrower is the only support weapon that is not mounted on a turret mount, although it is described as being usually carried about on a cart rather than used as a handheld weapon.
 * If the Arbiter is killed near a support weapon that is off its mount, he will use it when he gets back up.
 * Other than the Flamethrower, all deployed support weapons in multiplayer have limited ammo regardless of whether the infinite ammo option is turned on or off.
 * Standard weapons like the Brute Shot and the Sentinel Beam function similarly to support weapons: they are held the same way, and have more firepower than normal weapons though you can still melee or throw grenades and you can only carry one other weapon while wielding them.
 * In Halo PC, Flood combat forms have the animation and programing required to wield the Flamethrower. However, when they shoot it at a player directly in front of them or below them, they point it at a 45 degree angle in the air, making them not so effective when wielding it.
 * Support weapons are especially useful in Multiplayer because the third-person point of view lets you see around corners without any part of you visible or vulnerable to enemy fire.
 * If you're driving a vehicle in Multiplayer, it's a good idea to ram into the enemy team's machine gun turret and knock it off its supports to make it less of a threat if the enemy tries to use it against you later. A direct impact from any vehicle will break a support weapon off its base.
