Standard UNSC Armour:
Black BodySuit:
This suit of combat armor only referred to as the black body suit is a vacuum-enabled suit of light body armor used by the United Nations Space Command in operations in vacuum environments.
This Body Suit is a black, form-fitting suit of polymer body armor, able to deflect small-caliber rounds.
The suit is equipped with cooling and heating units that masks the infrared signature of the wearer, as well as creating a comfortable environment. The helmet has encrypted communications gear and a HUD, along with thermal sensors and motion detectors. The whole suit is fully sealed and gas tight, making them wearable in vacuum for up to fifteen minutes when equipped with an oxygen tank.
Unfortunately, the suit's general complexity leads to complications. Over prolonged periods of time the suit will become very uncomfortable to wear, is difficult to repair in the field, and is often in need of frequent repairs.
ODST Battle Armor:
The ODST battle armor, or Battle Dress Uniform (BDU for short) is a suit of combat armor worn exclusively by the Orbital Drop Shock Troopers, special-operators of the UNSC Marine Corps. The ODST battle dress uniform is made up of several different components and layers that make the suit what it is, while technology from other projects across the military have been incorporated into the suit, ODST equipment still has proprietary technology that has not been adopted into other equipment for the military.
The ODST helmet is made of titanium, coated with a heat resistance material to help disperse heat - the inside is lined with black padding to provide comfort when the user is wearing it. The helmet's faceplate is made of a strong, glass-like material with the ability to polarize. When polarized, the helmet's faceplate has a silver blue color to it, and obscures the wearer's face completely.
The rucksack issued to ODSTs is, for all intents and purposes, an armored backpack that attaches to the back of the armored vest. The rucksack comes in a number of different variants. The main purpose is storage, which allows a trooper to store equipment, ranging from ammunition, to medical supplies, to explosives, to battery packs which provides power to any equipment an ODST may carry, and communications, which houses the necessary radio and satellite gear that an ODST squad requires to report in to their superiors.
The ODST body suit is made up of several different layers and materials, the inner layer of the black-gray undersuit is made up of Kevlar material to aid in protecting the wearer from small arms fire, the inner layer also contains a heating and cooling system which regulates temperatures to keep the user warm or cool depending on the weather conditions - the heating and cooling system can also match infrared signatures of the current weather as well to allow an ODST to go undetected in hostile locations.ODST armor is compatible with several upgrades, including Up-Armor plates, a Command Network Module, a Hardened Uplink Module for MILINT acquisition, and a CBRN module for operations in hazard zones.
UNSC Marine Corps Battle Dress Uniform
The UNSC Marine Corps Battle Dress Uniform or BDU is the standard-issue combat uniform worn by the members of the UNSC Marine Corps. Inferior to more sophisticated armor suits such as the Battle Armor worn by the ODSTs or the MJOLNIR Armor worn by the SPARTANs, the armor relies on more traditional methods of protection.
As opposed to the Dress Uniform worn at parades and functions, the BDU is intended for use in combat situations. As a large fighting force, the UNSC Marines use a great variety of different BDUs. Standard Marine Battle Dress Uniform consists of armor plating over camouflaged combat utilities, and includes a number of ammunition pockets, holsters, and other features.
Unlike the radically more advanced MJOLNIR Armor worn by the Spartan-II soldiers, the Marine BDU does not include a dynamic recharging energy shield, providing far inferior protection against directed-energy and projectile weapons.
Camouflaged combat utilities are worn under the armor. The UNSC is known to use a variety of camouflage patterns depending on the environments, including all-grey fatigues, woodland camouflage, urban camouflage or winter camouflage. Combat boots such as the VZG7 Armored Boots are worn with the uniform, usually equipped with different types of additional armor to provide greater protection to the lower leg.
The Marine BDU is equipped with ballistic armor in multiple points, such as the torso, shoulders, and the lower legs. Some versions incorporate armor in the forearms and thighs as well.
The armor is extremely resilient towards traditional ballistic weaponry. However, it is easily damaged by plasma weaponry. The armor consists of several layers, some of which include a ballistic recoil-absorbing gel layer and a heat reduction gel layer to help reduce velocity and felt shock from ballistics, shrapnel, and explosives as well as reducing the burn caused by plasma once it reaches flesh.
This heat reduction layer also reduces the chance of the plasma penetrating by counter-acting and dissipating the heat, effectively disarming the blast. While this armor protects the wearer from harm caused by weaponry it also has temperature-regulation units integrated into it to keep the wearer at optimum supportability while eliminating the need to change depending on the environment. This also reduces the enemy's ability to track soldiers via thermal energy as it is mostly hidden beneath this armor.
Marine helmets are mounted with high-tech equipment, such as holographic text-displaying eyepieces, helmet recorders and microphones. Tactical goggles are also used by some Marines. The CH252 Helmet and its variants are standard issue. As well as helmets, Marines on field operations in more humid locales sometimes choose to wear boonie covers, or those in colder environments don visored and thicker helmets. Marines have a Heads Up Display not just from their helmets, but from their standard Neural interface which projects HUD data directly to the Marine's retina. In hazardous situations, Gas Masks such as the S90 Gas Mask are worn.
Marine NCOs are easily recognized by the cover that they wear complete with the UNSCDF insignia, although they often times substitute this soft cover for a more practical protective helmet.
UNSC Marine Corps Battle Dress Uniform, Pilot Varient:
Marine pilots usually wear a modified version of the standard Marine uniform, though they are known to utilize the BDU without modifications as well. The helmet is often different from the standard Marine helmet. Pilots weare more advanced equipment, fully-sealed helmets and an additional control panel on the standard chest armor piece. Each helmet bears a wing symbol, likely denoting the pilots' particular specialty.
