MA2B assault rifle

The MA2B Individual Combat Weapon System is a firearm used by the United Nations Space Command that is part of Misriah Armory's MA Series. In function, it is essentially a cut-down version of UNSC's standard-issue MA5B Individual Combat Weapon System. It sees sparse service among UNSC Special Forces units.

Background
Like the other models of the MA series, the MA2B is tough and reliable. It has electric targeting, an ammo supply indicator, and a recoil-reduction system. The MA2B can fire 900 rounds per minute (fifteen rounds per second) and uses .390 caliber ammunition, which is considerably larger than the 7.62mm round used by the MA5 Series.

In addition to the standard armor-piercing rounds found in most human firearms, the MA2B can utilize shredder rounds: an anti-personnel ammunition type made from depleted uranium.

The SPARTAN-IIs used MA2Bs when they were required to carry very little ordnance for a mission. Blue Team used MA2Bs on their first combat mission to capture Colonel Robert Watts of the Insurrectionists.

Trivia
In the first three issues of Halo: Fall of Reach - Boot Camp, the MA2B appears as it is depicted on the cover of Issue 4, albeit longer. In the last issue, however, the MA2B closely resembles the MA5K Carbine due to its straighter carrying handle and larger barrel. In some panels in Issue 4, John-117's MA2B appears to be much longer than in other panels, making it look almost identical to the BR55 Heavy Barrel Service Rifle.
