UNSC Marine Corps Battle Dress Uniform

Various iterations of the Marine BDU

Battle Dress Uniform (BDU) is a broad term describing any of several standard-issue combat uniforms worn by members of the UNSC Marine Corps.

Overview

Unlike the Marine Corps Dress Uniform, which is worn at parades and functions, the BDU is intended for use in combat situations. Though the Marine Corps fields a great variety of BDU types, all models comprise armor plating over camouflaged combat utilities, as well as a CH252 helmet and combat boots. Ammunition pockets, holsters, and rucksacks are commonly used in conjunction with the BDU.

Unlike the MJOLNIR Powered Assault Armor worn by the Spartan supersoldiers, the Marine BDU does not include a recharging energy shield, providing inferior protection against directed energy and projectile weapons.

Ushuaia Armory performed a substantial amount of work on at least one version of the BDU.

Components

Fatigues

Camouflaged combat utilities are worn under the armor plating. Woodland, desert, and urban camouflage are the most common color patterns for Marine fatigues.

Combat boots

Combat boots such as the VZG7 armored boots are worn with the uniform. They are sometimes equipped with different types of additional armor to provide greater protection to the lower leg.

Armor

The Marine BDU is equipped with one of various models of ballistic armor at multiple points, including the torso, the shoulders, and the shins. Some versions incorporate armor for the forearms, thighs, and groin as well. The armor is resilient against traditional ballistic weaponry though it is easily damaged by plasma weaponry. While different iterations of the BDU feature different armor models, all possess roughly equivalent durability. Lighter body armor, such as the ballistic assault vest, is used in lieu of standard-issue gear during some operations.

Headgear

Main article: CH252 helmet

All iterations of the BDU feature one of several versions of the standard-issue CH252 helmet, which is painted to match the corresponding body armor. The helmet may be mounted with various accessories, such as a holographic tactical eyepiece, a helmet recorder, a boom microphone, polarized tactical goggles, a flashlight, or a night vision device. Marines sometimes wear balaclavas with their helmets, both in frigid and temperate climates. In hazardous situations, gas masks such as the S90 gas mask are worn.

Marines on field operations in more humid locales sometimes choose to wear Boonie covers. Marine non-commissioned officers are easily recognized by the cover that they wear, which features the UNSC insignia, although they often substitute this soft cover for a more protective helmet.

Primary models

Several versions of the Battle Dress Uniform are in service, one of which is shared with the Army and the Air Force. The issue of any given model depends on environmental conditions, combat type, and the wearer's role.

Insurrection and Human-Covenant War era model

The earliest known iteration of the Marine Corps BDU was in use during the Insurrection and continued to see service well into the Human-Covenant War, with some units fielding this model as late as 2559 in the Second Ark Conflict in the Post-War era due to cryo sleep. Notably, this model was standard issue during the Harvest campaign and saw extensive use during the early stages of the Battle of Earth. The fatigues have a two-tone greenish gray camouflage, whereas the armor is issued in both reflective drab and matte forest green. The cold environment fatigues use the same camouflage pattern with white in place of green; similarly colored armor and a matching helmet are worn with this version. The shoulder pauldrons for this model come in at least two designs: the standard version has a broad, concave form that covers the shoulder and most of the upper arm, while an off-hand variant is thicker and sits higher on the arm, extending well beyond the shoulder. Marines issued this variant often wear polarized tactical goggles and balaclavas, even in temperate environments. The chestpiece used with this model is composed of very heavy plating. The forearms, shins, and boots are fully armored. Some users wear tactical thigh rigs or holsters, while some wear armor covering the thighs. Often the left thigh is armored while a holster is attached to the right thigh.

BDU with M52B body armor

This version of the BDU had entered service by 2531, and was used by Marines during the later stages of the Battle of Earth, as well as on Kholo, Algolis, Sigma Octanus IV, and numerous other planets. This model is based around the M52B body armor, which can be outfitted with various accessories such as utility webbing and ammunition pouches; the armor is supported by a black ballistic vest that extends to the arms. The armor and helmet used in conjunction with this model are almost universally painted olive drab, while the fatigues generally feature a woodland camouflage pattern.

This version of the BDU lacks the prominent shin armor used with other models, with only the upper shin being armored. This version also lacks thigh armor, though some Marines wear lightly armored holsters on their thighs. The BDU has black knee and elbow pads, although they are only lightly armored. The uniform also includes armored pauldrons. The VZG7 boots worn with the system are covered in light armor plating. Marines often wear fingerless gloves with this model. Rank insignia is sometimes displayed on the right shoulder pauldron.
