MA5B assault rifle

"Hey, soldier, is that an assault rifle in your hands or are you just happy to see me?"

- Janissary James

The MA5B Individual Combat Weapon System, abbreviated MA5B ICWS and commonly known as the MA5B assault rifle, is a standard-issue service rifle for the UNSC Marine Corps and the Navy. It is produced by Misriah Armory as part of its MA5 Series.

Overview
The MA5B Assault Rifle is an air-cooled, gas-operated, magazine-fed, fully-automatic bullpup rifle that fires 60 rounds of 7.62x51mm ammunition. It possesses a built-in ammunition indicator and magnetic compass for orientation similar to that of all other MA5 series rifles.

Accuracy
The most pressing negative aspect of the MA5B is its inconsistent accuracy. Firing the weapon in short bursts will allow much higher accuracy, as opposed to holding down the trigger. Most of the bullets will stay within the reticule. One round fired may produce a perfect bull's-eye, but the next may fly out of the targeting reticule and slam into the dirt a dozen meters from the same target. This has led to the belief that the rifle is very incapable of hitting targets greater than close-range; this is untrue. If attacking targets at surprisingly long-ranges, one can effectively wound or kill that target by firing in single shots or bursts. Unfortunately, this lack of consistent accuracy has tarnished the image of the rifle, and the problem has kept the MA5B out of the hands of those who prefer less spontaneous weapons.

Advantages
The MA5B in both offensive and suppressive situations remains one of the UNSC's most reliable weapon. When fired in short bursts, or even single shots, there is a significant increase in accuracy, and the rifle's armor penetrating ability makes it key for handling even the toughest of infantry, having the ability to kill an Elite in about 45 rounds in close quarters. The MA5B rifle is effective at killing light armored infantry at close-to-medium range, and the high rate of fire combined with the high ammunition capacity allows its user to spray the whole area with suppressing fire. The MA5B also gives the user an ammo count on its digital readout, as well a compass pointing toward the arbitrary magnetic "north" position. In the hands of someone who can control their trigger finger, the MA5B becomes a deadly weapon in CQB situations.

Disadvantages
The MA5B is not without disadvantages, its main disadvantage being its horrible accuracy when fired at a range of more than forty meters. At that range, enemy infantry may be hit by a few bullets, or not be hit by any bullets at all. The MA5B Assault Rifle performs poorly against energy shields unless firing on full automatic at close range without giving a shielded infantry time to cover. In comparison to modern assault rifles it can be more related to an oversized sub-machine gun, as it is underpowered and lacks the ability to select a fire mode.

Miscellaneous

 * There is a second melee animation for the MA5B, in which the user holds the weapon vertically and clubs anyone in front of them with the back end of the weapon. This animation is used in a few Halo Custom Edition maps, but was taken out of the official game. This animation is similar, if not identical, to the melee animation used for the M90 CAWS.
 * In Halo: Combat Evolved and Anniversary, the gas giant Threshold is considered arbitrary north by the MA5B's compass.
 * In early builds of Halo: Combat Evolved Anniversary, the MA5B used the MA37 assault rifle's model as a placeholder. The final game uses the MA5C's model from Halo 3. Although the MA5B and MA5C are largely identical, this means that the MA5B's sloped electronics cowling is conspicuously absent.
