ODST battle armor

Were you looking for the black body suit, a vacuum-enabled suit of light armor?

ODSTバトルアーマー, または ODST用戦闘服(通称BDU=Battle Dress Uniform)は、UNSC海兵隊に所属する特殊部隊「軌道降下強襲歩兵（ODST)」の隊員が着用する戦闘服である。

Introduction[]

ODSTバトルアーマーを使用する部隊で最も著名な部隊は第105ODST師団である。このアーマーは着用者の体温を一定に保ち、銃弾などの攻撃から着用者を防護するだけでなく、コヴナントのエネルギー兵器で攻撃された際や大気圏突入時に生じる熱から着用者を守る為の断熱効果を発揮するように設計されている。それらに加えて、宇宙空間でも約１５分間の船外活動が可能な宇宙服としての能力をも付加されている。^[1]

ODSTバトルアーマーは、コヴナント戦争の開戦以来幾度ものバージョンアップを重ねている。現在では当初、スパルタン用のミョルニルアーマーの為に開発された技術も組み込まれている。 This includes CTCs for body armor, titanium and ceramic composite armor plating to give the user added protection - along with HUD and Communications Systems to give more situational awareness to the wearer.^[2]

この戦闘服は第105ODST師団を始めとする各ODST部隊によって、細かな改良を加えつつも半世紀以上に渡って使用され続けている。ODSTバトルアーマーはUNSCの他の歩兵部隊が使用しているアーマーよりも小火器の攻撃に対する防御性能が優れており、暗所（宇宙空間を含む）や都市部でのステルス性能に優れた黒いボディアーマーは、着用者の生存率の向上に一役買っている。また全てのODST隊員は、左肩にUNSC MED REFパッチを着けている。^[3]^[4]^[5] このパッチにはその隊員の基本的な医療情報が書き込まれており、UNSCの衛生兵はこれを戦地で負傷したODSTに対する迅速な医療処置に役立てる事ができる。しかしこれら標準的なアーマーよりも優れた利点を有しているにも関わらず、コヴナントのエネルギー兵器や爆発性の武器に対しては、十分な防御性能を発揮できるとは言いがたいようだ。

Armor Variants[]

While the standard ODST BDU is fully capable for any role, there are specialized variants of the BDU - these suits are specifically issued to a specialist of a certain field to provide them certain advantages during an operation. As such, specialized gear is only available by Mission Conditional Requisition (MCR). Depending on mission requirements, an ODST operative may request either additional, or variant equipment that ranges from helmet attachments, gloves, battery, equipment or communication rucksack. The following is the specialized battle dress uniforms currently in use by the Navy.

Close Quarters[]

While designated as a CQB suit, this variant is also issued to demolition experts in the field. This BDU is specifically designed to aid an ODST in CQB type combat conditions. The standard left pauldron is replaced with a longer two piece ballistic plate, which aids in protecting the trooper's upper body while in a firing stance, and also to reduce severe injury from plasma-based weaponry. The helmet is also issued with an optics device that aids the user in relaying images and video to teammates or command.

Sharpshooter[]

The Sharpshooter BDU is issued to sniper experts in the field. This BDU is designed to give an ODST sharpshooter more freedom in combat - the standard right pauldron is removed, allowing the sniper to aim better and move his arm more freely with a sniper rifle, while the standard left pauldron is replaced with a larger plate to protect the sniper's arm from counter attacks. The Sharpshooter variant is also issued with an optics device attached to the helmet, while the Oracle scope on the SRS99 can uplink to the user's HUD.

Recon[]

The Reconnaissance BDU is a specialized Office of Naval Intelligence variant of the ODST Armor. The armor is only issued to ONI reconnaissance agents for high risk operations. The undersuit is the same as the standard ODST armor. However, the chest plate is replaced with a specialized one, to provide stealth capabilities with little or no loss of endurance, specifically by reducing its IR signature and reflective surfaces. The torso part of the armor also varies from the standard version, having a green, translucent orb in the center. There are no shoulder plates issued with this variant, which allows more freedom of the arm movement.

Other Versions[]

There are also variants or models of the ODST armor that have not been named; one example of this is a suit that ODSTs Gretchen, Dutch and Romeo wore during a mission some time prior to the Battle of Ariel. It differed greatly from the normal ODST armor in that it bore a great resemblance to standard Marine armor. The chestplate that Romeo wore was olive drab in color, and appeared almost identical to those worn by the Marines. However, the armor retains the basic form of the ODST armor, with standard helmet and bodysuit pieces obviously shown. It is possible that this variant is either an earlier version of the armor or a field-expedient modification, or it could just be that the illustrator took artistic liberties .

アーマーを構成する各パーツ[]

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.

ヘルメット[]

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 helmet provides excellent protection against small arms fire and small explosive attacks. The helmet is also essential in providing an ODST the ability to perform EVA and also provides a Heads Up Display, giving the wearer basic information including a targeting reticule, weapon information, ammo capacity, and basic health readout. The newest version of the helmet integrates with the user's standard Neural Interface to provide more tactical data to the HUD. Helmet integrated neural interfaces is another piece of technology that has seen widespread adoption from Project MJOLNIR. Along with this state-of-the-art equipment, the helmet is also equipped with its own thermal imaging and motion sensors.^[6] The MJOLNIR Powered Assault Armor/AA variant was developed as an improvement of the ODST helmet, indicating intended use by ODST personnel as well as SPARTAN-II or SPARTAN-III teams, ultimately it is used exclusively by Army Airborne units as stated in The Armory's description.^[7]

VISR[]

Main Article: Visual Intelligence System, Reconnaissance

The Visual Intelligence System, Reconnaissance or VISR, is issued with the ODST helmet. The VISR proprietary data management suite enables a user to link into UEG, CAA, and UNSC infrastructure systems at the local, national, and global levels - however actual access level is administered on a need/rating basis.^[8] This allows the user to store and review mission content up to 610MB combined, the system also provides street level navigational data, and receive secure real-time mission data. In addition, every current issue helmet ODST BIOS A29.817941B.01 or later is equipped with low-light vision enhancement, which outlines hostile units in red, friendlies in green, weapons in blue, and objects of interest in yellow.^[4]

Rucksack[]

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. For longer missions, ODSTs can carry larger rucksacks with enough supplies for two weeks of operation without external resupply.^[9] Rucksacks have integrated magnetic holding devices to allow for external back mounting of additional equipment. Equipment with magnetic properties, such as longer weaponry, can be carried externally over the rucksack eliminating the use of extra straps or slings.

ボディスーツ[]

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.^[6] The outer layer of the undersuit is coated with a heat resistance material to aid in reducing temperatures experienced during orbital drop, and against Covenant Plasma Weapons. The body suit also doubles as a pressure suit to allow an ODST to perform EVA. The outer shell layer is comprised of Titanium and Ceramic composite armor plating that covers the chest, shoulders, legs and feet.

Upgrades[]

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. This has only been seen used on SPARTANs that use the ODST helmet. It is unknown if these upgrades are used by the actual Orbital Drop Shock Troopers.

Multiplayer Variant[]

All ODST armor permutations in Halo: Reach.

The ODST battle helmet is available as an armor permutation in the Halo 3 Multiplayer component. The SPARTAN version of the helmet differs from the standard version in the polarization color of its visor; regular ODST helmets have blue/silver polarization, while the MJOLNIR ODST helmet retains the gold electroplating possessed by most MJOLNIR armor. It is attained and unlocked by the Spartan Graduate Achievement, or by earning 5 XP in Matchmaking.^[2]

The shoulder pauldrons, breastplate, and helmet of the ODST armor are also available for purchase in The Armory in Halo: Reach.^[10]^[11]

Trivia[]

The ODST armor is derived from the first concept of the MJOLNIR armor. This original concept done by artist Shi Kai Wang was scrapped because it made John-117 look "too mean."^[12]
The visor's ability to polarize, the VISR mode, and the HUD it displays may mean it has a transparent Organic Light Emitting Diode (OLED) screen coating it.
The Good Samaritan achievement unlocks the ODST armor for your Xbox Live Avatar, if the user has Halo Waypoint. It's listed under the "Awards" section when customizing the avatar.
It should be noted that the armor used by the ODSTs in Halo 3: ODST is similar to the one seen in Halo 3, despite the game taking place during the events of Halo 2. This suggests that the changes between the games are merely aesthetic and that there is no canonical difference between the Halo 2 and Halo 3-era suits.
The ODST armor worn by the Squad in Halo 3: ODST have the exact same scratches and burns. All the male members of the team wear the exact same armor with different colors and "Add-ons". This is easy to see if you pay attention to the chest plate, they all have the same scratches.^{[citation needed]}
To replicate the ODST armor from Halo 2 in Halo: Reach, you need to purchase the Air Assault helmet base, GUNGNIR shoulders, UA/ODST chestplate, NxRA utility, GUNGNIR kneeguards, and the silver visor, with your primary and secondary color being steel.
To replicate the ODST armor from Halo 3 and Halo 3: ODST in Halo: Reach, you need to purchase the ODST helmet base, ODST shoulders, ODST chest, PARA kneeguards, and the blue visor, with your primary color being steel and your secondary being either steel, red or white.

Note that the HU/RS package attachment that is used by all of the ODSTs in Reach is not available to the player.
The MJOLNIR Powered Assault Armor/AA variant bears a striking resemblance to the Halo 2's version of the ODST helmet. The description of the AA helmet states that it is an improvement of the ODST helmet.
Mega Bloks has apparently produced three sets of ODSTs with complete armour. They are equipped with three weapon types: Battle Rifle and Sniper Carbine; Rocket Launcher and Submachine Gun; as well as Shotgun with dual pistols. They also come with their Insertion Pods and a combat backpack. These troops are featured in different packages.
- Other sets have been released that include ODSTs as well as other drop-pod sets.
