MA37 Individual Combat Weapon System

The MA37 Individual Combat Weapon System (abbreviated MA37 ICWS or MA37 Assault Rifle), or more formally the Individual Combat Weapon System, Caliber 7.62 mm, MA37, also known as the MA5 by the UNSC Marines and Navy, is a standard-issue service rifle of the United Nations Space Command. It was first introduced in 2437, and has remained as the primary service rifle of all branches of the UNSC ever since.

Design Details
The MA37 is an air-cooled, gas-operated, magazine-fed, fully-automatic bullpup rifle that fires 32 rounds of 7.62x51mm ammunition. It possesses a built-in ammuntion indicator for orientation similar to that of all other MA5 series rifles. It has a high rate of fire, but due to its inaccuracy, it is highly ineffective at long ranges and inflicts low damage against energy shields.

The MA37 ICWS is a close to medium range weapon. It is most effectively used by fully automatic sustained fire at close range, or by using short, controlled bursts at medium range. It is a balanced starting weapon that can be used effectively in the hands of a skilled player.

Changes from MA5C ICWS in Halo 3

 * Major cosmetic changes such as a more 'skeletal' and detailed body
 * More powerful firing sound
 * New reload and pick-up animations
 * Shorter overall length
 * Changes that affect most UNSC weapons in Halo: Reach, such as hitscan and reticle bloom
 * Slightly slower rate of fire (by about 40-50 rounds per minute)
 * Larger reticle
 * Short, controlled bursts are slightly more accurate
 * Less damage (18 rounds to kill a fully-shielded SPARTAN player, rather than 16 rounds)

Trivia

 * Bungie stated that the MA37 "will feel most similar to the Assault Rifle of the original Halo".
 * "MA5C MK. 4" is stamped on the side of the MA37. It is yet unknown why this is so.
