The MUTA-AP-09334 is a type of ammunition manufactured by Humans and used in handheld machine guns. MUTA-AP-09334 is designated as armor piercing ammunition, and is only used against light tanks or enemies wearing advanced armor systems such as the MJOLNIR armor. MUTA-AP-09334 is .30 caliber, allowing it to be used in "Confetti Maker" MGs. It is unclear if the UNSC uses this type of ammunition, but it has fallen into use by the United Rebel Front.
