MA5K carbine

The MA5K Carbine is a United Nations Space Command firearm used by Special Operations Forces.

Design Details
The MA5K is a cut-down version of the standard MA5 Individual Combat Weapon System. The weapon is most likely lighter and easier to carry than larger assault weapons. Aesthetically, it resembles a cross between an MA5 ICWS and a BR55 Battle Rifle, although the MA5K functions more like an assault rifle. It features a stripped-down design that appears almost skeletal.

Based on current-era tactical philosophy, it is believed that the MA5K version was produced specifically for Special Operations forces because of its lighter frame, which allowed for more quick maneuvering and less visible profile, and probably for its lighter aural signature, which suits the requirements of commando missions well. This would make it well suited for Marine Shock Troops and vehicle crews as well, since it would not take up much room inside a vehicle.

Operational History
MA5Ks were not as often used for front line duty because of their reduced stopping power, but they were used by the SPARTAN-IIIs from 2531 to 2552, especially during the Battle of Onyx.
