M343A2 Minigun

The M343A2 Minigun, more commonly known as the Chaingun, is a heavy weapon featured in Halo 5: Guardians. It succeeds the M41 and M46 Light Anti-Aircraft Guns, and inherited their "chaingun" moniker. The chaingun is a five-barrel electrically-driven gatling style weapon, and are installed on M12 Warthogs on a pneumatic full-rotation turret, or on a semi-portable tripod when used on the field; it is also compatible with all UNSC-standard heavy weapon mounts. Lethality is roughly similar to the older gun units, and it will still overheat after periods of sustained fire, though barrel wear is substantially reduced. The M343A2 is also designed to use the latest polymer-cased and energetic propellant rounds; however, UNSC units have been ordered to deplete existing stocks of older ammunition before making the transition. It was employed by the UNSC in conflicts after the Requiem Campaign. As support weapons, picking up the chaingun would result in a lack of mobility.

Description
The turret behaves like the M247H Heavy Machine Gun in previous Halo titles.
