A general purpose squad support weapon used in Aliens by privates Drake and Vasquez. Although less manoeuvrable than the M41A Pulse Rifle, it does pack a greater punch. The smart gun fires M350 10x28mm caseless rounds at 1200 rounds per a minute. The 1.2 metre weapon weighs in at just under 18kg and is powered by a DV9 battery, which contains enough juice for up to 50000 rounds. The weapon is hip mounted via a combat harness and articulation arm. This setup distributes the weight to the body and allows better control. The system has aim-adjustment functionality linked to the head mounted sight (HMS).
Although this weapon was effective at bringing down the xenomorphs, its bulkiness reduced any benefits when used in close quarters.
