Post-Covenant War conflicts


The M49 Vulcan, formerly the M343A2 Minigun, is a heavy machine gun in use by the United Nations Space Command after the Human-Covenant War. It is a successor to the M41 and M46 machine guns, with which it shares the erroneous "chaingun" moniker.[1][2] Despite seeing a high initial production run in early 2558 the debilitation of a number of key manufacturing sites led Misriah Armory to ramp production back up on the M46.[3]


The M343A2 is an electrically driven, five-barreled Gatling-style machine gun that is compatible with all standard UNSC heavy weapon mounts. The M343A2 is often installed on a pneumatic full-rotation turret as the primary armament of the M12B Warthog, and is also available in a semi-portable tripod configuration for site defense.[1] The latter configuration has a much shorter barrel assembly.

The M343A2's lethality is comparable to that of its predecessors. Barrel wear is considerably diminished in comparison, though the weapon will overheat after periods of sustained fire. Although the M343A2 is designed to use the latest polymer-cased and energetic propellant rounds, UNSC units have been ordered to deplete existing stocks of older ammunition before transitioning to newer cartridges.[1] As opposed to its predecessors, the M343A2 ejects its spent casings from the left side.


  • ONI Chaingun Turret: A variant used by the Office of Naval Intelligence. Fires explosive rounds with increased damage and does not overheat. Kills Spartans in 5 rounds in War Games. It is ranked an Ultra Rare REQ in Warzone simulations, and is available at Level 5 energy while giving 150 REQ points if sold.
  • Needle turret: A variant that fires blamite. Kills Spartans in 6 rounds in War Games.


Carrying the turret decreases the player's speed and maneuverability as in previous titles. However, it should be noted that this actually renders the player invisible on the motion tracker unless the weapon is fired, making the M343A2 useful for catching the enemy off-guard while on defense. The M343A2 kills Spartans in 12 rounds in War Games. It is ranked a Common REQ in Warzone simulations, and is available at Level 2 energy while giving 50 REQ points if sold.

Production note[edit]

The weapon's designation is an obvious reference to 343 Industries.


List of appearances[edit]


  1. ^ The in-game description states the weapon is an autocannon, though this conflicts with its Halo Waypoint universe page which claims it is a machine gun chambered in 12.7×99mm, a round not large enough to classify it as an autocannon.
