MA37 assault rifle

The MA37 Individual Combat Weapon System, formally known as the Individual Combat Weapon System, Caliber 7.62 mm, MA37, is a member of the MA5 series of assault rifles. Favored by the UNSC Army, it also saw service with the UNSC Marine Corps and UNSC Navy and was known as the MA5.

Overview
The MA37 assault rifle is an air-cooled, gas-operated, magazine-fed, fully automatic rifle that fires 7.62×51mm ammunition. The MA37 is modular, which allows for easy cleaning and repair.

Development history
It first entered service with the UNSC in the year 2437 and has been consistently in production since. Copies of the weapon were mass-produced at the Misriah Armory Rajtom Facility on Reach. The later MA40 assault rifle was similar in design and featured several improvements over the MA37 including reliability and durability.

Usage
It was primarily used by Army assault teams and preferred in planetary defense. It saw use during the Battle of Alpha Corvi II, and was the predominant small arm used during the Fall of Reach. It also saw service in the Battle of Mombasa.

In the Post-Covenant War conflicts, it saw use in the Battle of Draetheus V and the Second Ark Conflict.

Differences from MA5C ICWS in Halo 3

 * Major cosmetic differences such as a more skeletal and detailed body, shorter overall length, ammunition counter appearing as an attachment rather than an integrated part of the weapon.
 * Maximum ammunition capacity decreased from 352 to 288 rounds.
 * Slower rate of fire and decreased damage per round: takes 19 shots to kill a fully shielded Spartan instead of 16.
 * Larger reticle. Short, controlled bursts are much more accurate than sustained fire.
 * Shots have increased projectile speed; shots fired would hit almost instantly.
 * Reload, melee animations, and firing sound have been changed to make it feel more like the MA5B from Halo: Combat Evolved.

Trivia

 * If the player participated in the Halo: Reach Multiplayer Beta, which was obtainable with a copy of Halo 3: ODST, a unique nameplate emblem of an MA37 is obtainable for use on Xbox LIVE in multiplayer.
 * The binary code 01000100011000010111011001100101 is displayed at the bottom left of the MA37's ammunition counter. This represents "Dave," in reference to Dave Candland, UI designer for Halo: Reach.
 * Although only the MA37's fully automatic setting is used in-game, the fire mode selector is modeled in the semi-automatic position.
 * In the Halo: Combat Evolved Anniversary announcement trailer, the MA5B assault rifle uses the MA37's model as a placeholder model. In the final game the weapon uses the MA5C's model from Halo 3 and Halo 3: ODST.
