MA37 Individual Combat Weapon System

The MA37 Individual Combat Weapon System (MA37 ICWS or MA37 Assault Rifle) was a standard-issue service rifle of the United Nations Space Command. It was first introduced in 2437, and is a UNSC Army designated variant of the MA5 series of rifles, which the latter is the name given to the rifle series within the UNSC Navy and the UNSC Marine Corps.

Design
The MA37 is an air-cooled, gas-operated, magazine-fed, fully-automatic bullpup rifle that fires 7.62x51mm ammunition. It possesses a built-in ammo indicator for orientation similar to that of all other MA5 series rifles. It has a high rate of fire, but due to its inaccuracy, is it highly ineffective at long ranges and inflicts low damage against energy shields. The weapon has a 32 round magazine and unlike in Halo 3 the user must fully deplete the targets shield before a instant kill melee attack is possible.

Trivia

 * Bungie has stated that it "will feel most similar to the Assault Rifle of the original Halo".
