The '''12.7×99mm Armor-Piercing''' is a round used in the [[M41 Vulcan|M41 Light Anti-Aircraft Gun]] that is mounted on the UNSC's [[M12 Warthog]] vehicle.  
The ''12.7x99mm AP'', also known as the [http://en.wikipedia.org/wiki/.50_BMG .50 Browning Machine Gun'] [http://en.wikipedia.org/wiki/.50_BMG .50 BMG] and the [http://en.wikipedia.org/wiki/.50_BMG .50 caliber'] is a cartridge that first entered service in the early 20th Century. The round is based on a greatly scaled-up [http://en.wikipedia.org/wiki/.30-06 .30-06] cartridge. The cartridge itself has been made in many variants: multiple generations of [http://en.wikipedia.org/wiki/Ball_ammunition regular ball], [http://en.wikipedia.org/wiki/Tracer_ammunition tracer], [[armor piercing]], [http://en.wikipedia.org/wiki/Incendiary_ammunition incendiary], and [[saboted sub-caliber]] rounds. The rounds intended for [http://en.wikipedia.org/wiki/Machine_guns machine guns] are linked using [http://en.wikipedia.org/wiki/Ammunition_Belt metallic links].


A wide variety of ammunition is available, and the availability of match-grade ammunition has increased the usefulness of [http://en.wikipedia.org/wiki/.50_BMG#Partial_list_of_.50_BMG_weapons .50 caliber rifles] by allowing more accurate fire than lower quality rounds.
