MJOLNIR Powered Assault Armor

The MJOLNIR (Pronunciation:ˈmjɔlˌnɪɹ, 'my-all-'nhr) Powered Assault Armor is a technologically advanced combat exoskeleton system designed to vastly improve the strength, speed, agility, reflexes and durability of a SPARTAN-II or SPARTAN-III supersoldier.

Introduction
Created parallel to the SPARTAN-II Program, the MJOLNIR Armor is currently the most advanced piece of tactical military hardware in human hands. Each suit alone costs as much as a small starship. The brainchild of Dr. Catherine Halsey, MJOLNIR is Halsey's attempt to create a powered exoskeleton capable of taking full advantage of the physical capabilities of a SPARTAN-II. The battlesuit is constructed in overlapping layers. It is a sealed system, capable of extravehicular activity or operations in toxic atmosphere. It is hardened against EMP and radiation, and has filters that are completely effective at removing toxins and bacteria from local atmosphere.

The armor's shell is composed of a multilayer alloy of remarkable strength and has been augmented with a refractive coating capable of dispersing a limited amount of Covenant energy weapon strikes. The suit contains a gel-filled layer underneath a thick black armored bodysuit. The gel layer regulates temperature and can reactively change its density. The inner skinsuit is made of a moisture-absorbing synthetic material linked to an environment control computer and the occupant's UNSC-issue neural interface.

Each human being has a molecular fiber network called the nervous system within their brain. An upgrade to the standard Neural Interface is issued to all high-ranking officers; another modified version of the neural lace is issued to all SPARTAN-IIs in the UNSC. This network translates electrochemical signals to digital code and routes them through an interface connection at the rear of the skull. Through this interface, the user's thoughts command the armor's movement and weapons; and input from the on board sensors comes directly to the user's mind. The synthesis of machine and mind is so fast that it is almost impossible to chart reaction time.

Between the external armor and the internal padding is the most devastating weapon the suit carries: a layer of computer memory superconductor. Woven by molecular tools into a superdense optical computer memory, this crystalline layer forms a network, capable of supporting the kinds of artificial intelligence usually reserved for starships, a piggyback system. An AI's personality and processing matrices can be carried by the armor and delivered to the suit via onboard storage in a crystal data chip no larger than a personal credit card.

The suit also possesses other features that enhance its wearer's abilities. It has numerous clips, belts, and magnetic holsters for the attachment of additional weapons and ammunition; an advanced Heads-Up Display (HUD), linked to sensors in the gloves which can detects the type of weapon and devices held, and to project shield strength, ammunition count, a targeting reticule, waypoints, a radio uplink for communication, health monitoring and restoration system, regenerative food materials and other helpful data.

In its final phase the MJOLNIR battlesuit weighs half a ton, or 1,000 pounds, and is a fully neural-linked system. With an on board AI using the human mind for parallel processing, the SPARTAN-II/MJOLNIR combination is designed to be the most devastating intelligence tool ever created.

The armor line is named for the mythical weapon Mjølnir, the hammer of Thor, the Norse god of lightning, thunder, wind, and rain. Thor was the God of Thunder, and possessed incredible power. It is said that Mjölnir had the power to level mountains. The origin of the word "Mjölnir" is unknown. The Icelandic verbs mölva (to crush) and mala (to grind) have been suggested as possible translations. Another theory suggests that MJOLNIR might be related to the Russian word молния (molniya) and the Welsh word mellt (both words being translated to the term as "lightning"). This second theory parallels with the idea that Thor, being a son of the Chief God, Odin, and the God of Thunder himself, might have used lightning as his weapon.

The Mark system was introduced in 2535 as a means of fiscal oversight. Thought Halsey disliked the system, she agreed to produce the MJOLNIR armor in distinct stages rather than through incremental improvements. However, she secretly vowed to provide the SPARTANs with armor upgrades as they become available.

Mark I Prototype Exoskeleton
Initiated in 2512 the Mark I was one of the Navy's first experiments with powered exoskeletons - more human-powered defense structures than suits, the Mark I took 10 years to develop, but was bulky, unwieldy and needed to be tethered to a power source due to the tremendous amount of energy needed to power it. This was the downfall to the system as it required a connection to a fusion generator which hindered movement. The Mark I Prototype Exoskeleton improved the strength and stamina of the wearer and allowed a user to lift two tons (4,000 pounds) and run at 32 km/h (19.88 mph) for extended periods of time. The Mark I contained a cutting-edge onboard computer that could assist the wearer by transmitting tactical and communications information to the standard neural implant issued to a soldier, the suit however did not posses the ability to carry an AI on board. The armor could also be equipped with motion sensors, infrared scopes, and could be mounted with a 30mm minigun that fired on self-targeting armatures.

Research and development for the Mark I was carried out at Section Three's headquarters in the CASTLE facility on Reach, however the final assembly of components were done at the Damascus Testing Facility on Chi Ceti IV. At least forty Mark I suits were produced and although they never saw deployment on the battlefield they were later used to carry heavy equipment in docking bays, and dozens of others were dumped into Reach's titanium mines. The Mark I Exoskeletons were later used by trainers of the SPARTAN-IIs to protect themselves when training under Chief Petty Officer Mendez's orders. Otherwise the training could have killed them, as evidenced by the first day back at Reach when three trainers were accidentally killed during hand to hand combat exercises.

Mark II Prototype Exoskeleton
The Mark II Prototype Exoskeleton was similar to the Mark I, but with slimmer profile which greatly increased mobility. The suit, however, still needed to be tethered to a Fusion Generator, so despite the fact that it was the most powerful piece of military hardware at the time, it was still impractical for battlefield deployment. One of the new additions to the Mark II included a refractive coating to help disperse heat from explosive attacks and better self-sealing in the event of damage while the unit is in space.

Mark III Prototype Exoskeleton
The next prototype, the Mark III, incorporated a wireless power transmitter and receiver so that power could be transmitted directly to it, much like the Orbital Defense Platforms used to defend UNSC colonies. This design was quickly rejected for two reasons: first, the armor still had a limited operational range as it had to remain within range of a bulky, immobile generator. Second, if the generator was disabled or destroyed, the suit would be disabled, leaving its user trapped inside an useless shell, helpless against enemy attacks. In the end, all of the first three prototypes had one thing in common: They were impractical on the battlefield, as their range are severely limited by the lack of a mobile power source.

MJOLNIR Mark IV Powered Assault Armor
Although earlier attempts at developing high-powered armor produced designs that were impractical for battlefield deployment, the Mark IV MJOLNIR powered exoskeleton would be the first successful powered armor that saw deployment onto the battlefield. Developed by Dr. Catherine E. Halsey, the MJOLNIR Mark IV was a radical redesign of powered exoskeletons making use of technological innovations that did not exist when work on the first MJOLNIR exoskeleton suit began, such as a miniature fusion reactor embedded in the armor. The Mark IV MJOLNIR armor was fielded November 27, 2525 to August 29, 2552.

MJOLNIR Mark V Powered Assault Armor
The MJOLNIR Mark V is the first major upgrade of the system and introduced two revolutionary technologies for battlefield purposes: energy shielding reverse-engineered from Covenant technology, providing the user added protection against plasma weapons, and the ability to link a soldier and an AI together to provide the soldier instant intel in the field, along with other functions. In addition to major changes from the Mark IV, hundreds of other technical improvements are incorporated into the Mark V: for example, the fusion packs used to power the suits are half the size of their predecessors. The Mark V was fielded November 24, 2551 to October 20, 2552.

MJOLNIR Powered Assault Armor/Black
Created by a top-secret parallel development lab in Seongnam, Korea, MJOLNIR: Black was a standalone "skunkworks" variant created exclusively for Team Black. It features a number of advances over even the then-current generation Mark V and the later VI. It was used on Verge during the Covenant invasion of the Epsilon Eridani System and Operation: BLOWBACK some time after.

MJOLNIR Mark VI Powered Assault Armor
The MJOLNIR Mark VI is the third and final upgrade to the MJOLNIR system, the Mark VI once again introduces several technical improvements while refining advanced technologies introduced in the previous system. The first improvement made to the system is a faster recharge time on the suits' energy shield system so that the SPARTAN-II super soldier does not have to remain in cover for an extended period of time. The second is improved synchronization between the suit and user, this allows the SPARTAN-II to jump higher, run faster, and hit harder than a Spartan could previously. In addition, a SPARTAN-II wearing the Mark VI no longer need medical kits, as the armor has an intergrated biofoam injector.

MJOLNIR Mark VII Powered Assault Armor
The MJOLNIR Mark VII was an armor system mentioned by Dr. Halsey in her personal journal. It would appear to be the last planned phase of the MJOLNIR project. At the time the MJOLNIR project began, Halsey had planned on the Mark VII suit featuring the following upgrades:
 * A power system that made use of a combination of plasma and fusion technology.
 * Integrated atmospheric insertion capabilities.
 * Slipspace de-insertion capability.
 * Active AI transfer protocols.
 * Limited shaping of the energy shield.

"Atmospheric insertion" would allow a Spartan to free-fall from space without a re-entry vehicle such as the ODST's SOEIV, but would most likely require a drag chute or parachute. Note that re-entry in MJOLNIR armor has been done several times in Halo fiction but is most likely outside both the Mark V and Mark VI design specs and has proven fatal. "Slipspace de-insertion capability" means a Spartan would be able to exit a vessel travelling in slipspace and re-enter normal space, similar to the Long Range Stealth Orbital Insertion Pod. "Limited shaping of the energy shield" implies the ability to form shapes or objects such as gauntlets or walls with the armor's integrated shielding, similar to a Kig-yar point defense gauntlet.

Because of the Fall of Reach, any work on the Mark VII was likely abandoned.

Armor Components

 * Helmet: The MJOLNIR Helmet is one of the most vital aspects to the MJOLNIR system. It is made of Titanium and contains key features like a Heads Up Display that links to the brain and hands, and can identify equipment and display information about it when it is picked up by the wearer. Another feature is the direct neural interface system which connects to a SPARTAN-IIs neural implants. Two core processor chips are implanted into the subjects skull in the rear of the head.  This is essentially comparable to an on board computer using parts of the human brain for processing - when the connector at the rear of the subjects head and receptors in the brain link to the helmets on board sensors it creates the neural link needed to move the MJOLNIR suit. The helmet also contains other equipment to protect and aid the user in hostile conditions.  This includes: filters to remove toxins from the atmosphere, a supply to provide air to the wearer during EVA, thermal and motion sensors, communications, solar-powered lighting, and imaging and video gear. The helmet also contains the A.I housing, where a ship-borne A.I chip is inserted, located on the back of the helmet.


 * Titanium Alloy Outer Shell: The outer shell of the MJOLNIR armor is comprised of a fairly thick titanium alloy. This plating covers the chest, arms, hip, legs, calves, feet and hands. This alloy is very resilient, can take significant punishment, and is nearly impervious to small arms fire. While enough shots from armor piercing rounds will breach the outer shell, the suit can take a few glancing blows from them without compromising the armor. The outer shell of the all MJOLNIR suits is covered with a refractive coating to help disperse the heat experienced from Covenant energy weapons. However one or two direct hits from any Plasma weapon will compromise the armor plating.


 * Titanium Nanocomposite Bodysuit: Sandwiched between the external armor and the internal padding is a thick black armored bodysuit. This suit has numerous functions, small but vital to the safety and survival of the wearer. The bodysuit is made of a titanium-based material, making it very strong and yet very flexible.  It also serves as another layer of protection against ballistics attacks and is coated with a heat resistant material to disperse heat from Plasma weapons.


 * Hydrostatic Gel: Underneath the armored bodysuit is a gel-filled layer, this gel layer regulates the temperature of the suit and can re actively change its density to conform to the wearer's shape - the temperature inside the suit is controlled by the moisture absorbing cloth suit underneath the hydrostatic layer. The hydrostatic gel layer can also be pressurized to various levels to potentially save the wearers life should the wearer be subjected to high G forces or a high velocity impact; however, over pressurizing this layer can cause nitrogen embolisms.


 * Reactive Metal Liquid Crystal Layer: Sandwiched between the external armor and the internal padding is a layer of piezoelectric material that deforms along a preffered axis when exposed to a electric charge. The term "Metal Liquid Crystal" is misleading, the crystal is only liquid while it is being poured into a formatic capillary system where electric charges can direct the crystalization and hardening process.  This layer acts as synthetic muscle, allowing the Spartan access to approximately twice their normal strength.  This is not due to a "Leverage Effect," but rather that a human-sized suit will provide about six hundred kilos of lifting power, in addition to an average Spartan's six hundred kilos of lifting power.  Assuming a Spartan has an average body weight of 200 kilos, and that CPO Mendez's assertion that:  "They can lift three times their body weight- which, I might add, is almost double the norm due to their increased muscle density," is indeed accurate.


 * Memory-Processor Superconductor Layer: A layer relatively new to the MJOLNIR line, introduced with the Mark V, that is capable of housing an A.I. Comprised of the same material as a starship's A.I. system, this layer allows an A.I. to travel with a soldier into the field.  The A.I. can then aid the soldier in software inrtusion, hardware hacking, and espionage by listening to enemy chatter.  As a side note, this layer is often confused with the Reactive Metal Liquid Crystal layer, which due to the latter's piezoelectric properties is impossible.


 * Magnetic Weapon Holder Strips: Available on the Mk. IV, Mk. V, and Mk. VI, the magnetic strips are very small yet powerful magnets place on the legs, waist, and back of the suit and is used to hold any equipment with a magnetic property. The suit also contains an electromagnetic system on the boots of the MJOLNIR suit that allow its wearer to stay attached to a metal surface in Zero G environments and can be toggled on or off by the wearer.


 * Energy shields: First used on the Mk. V, and later refined on the Mk. VI, the energy shield device is reversed engineered from Covenant technology. Begun in 2532 forty scientists and technicians would spend the next 20 years attempting to make some use of the technology. For decades the attempts at cracking their technology had met with failure after failure, some had given up and others in the scientific community believed the energy shield technology could never be cracked. However at some point before 2552 a breakthrough was made and for the first time the UNSC had successfully cracked and improved upon the technology.


 * Pressure Seal: The Pressure Seal is a vital component to the MJOLNIR system, it keeps the system airtight, underwater or in space. The seal is very strong and will only break under extreme pressure, such as in a high velocity impact or when the Hydrostatic Gel has been over pressurized.


 * Automatic Biofoam Injectors: Introduced on the Mk. VI models Biofoam injectors is an integral part of the systems ability to keep a SPARTAN-II functioning in battle. Biofoam is a medical gel that is used to fill and seal a wound automatically, it is also used to treat any infection that could occur as a result of the wound. The process of injecting, or applying the gel to a wound is extremely painful and is only a temporary solution; medical attention must be sought soon after to ensure survivability.


 * Fusion Reactor: The fusion reactor is the most essential part of the MJOLNIR System, as it provides power to all equipment on the MJOLNIR armor - the reactor is built into the suit and allows for nearly unlimited movement. The fusion reactor in all versions of the MJOLNIR armor are half the size of a normal fusion pack that conventional Marines use.


 * Force-Multiplying Circuits: Located throughout the armor, these systems boost the force applied by the user. They make hand-to-hand combat easier, but also make the armor difficult to adjust to; a slight motion can be translated into a potentially harmful one if not conducted correctly. For this reason it is only possible for Spartans to use this armor, as their strengthened bodies are able to withstand the increased power and speed of movement, which, in un-augmented human bodies, results in broken bones or death, due to spasms caused by the pain of broken bones.


 * Reactive Circuits: Reactive Circuits are systems installed directly linked to the Spartan Neural Interface. They amplify the wearer's reaction time by connecting directly to the thoughts of the wearer, making it much easier to control and allowing for the soldier to be both more efficient and have a higher survival rate in combat.


 * Power Supply Control Unit: The Power Supply Control Unit controls the power supply of the armor.

Trivia

 * Armor components developed alongside Project: MJOLNIR were later applied for use with other UNSC armor systems as well. This is the case with ODST battle armor, which uses technology developed for MJOLNIR. Similarly, a specialized "Recon" variant of the ODST armor, used exclusively by ONI operatives, utilizes a similar helmet as the Recon variant of the MJOLNIR armor.
 * In the Halo 3 public Beta, a Spartan's face was visible under the helmet's visor which could be seen by positioning a player a certain distance away from a Mongoose, and using the camera to view under the model. However, Bungie stated later that this was an Easter Egg Bungie made and that the face seen on the Beta was in fact modeled from the face of Marcus Lehto, a Bungie employee.
 * McFarlane Toys has produced Halo figures with interchangeable head, chest, and shoulder armor. The hands are also interchangeable, but aside for color effect, this will only matter with the release of the left gun hand released in February 2009, which allows the Spartans to dual-wield a weapon.
 * The Limited Edition of the Xbox 360 action RPG Fable II includes a set of MJOLNIR armor for the player's character to wear. It is called "Hal's Armor/Outfit". Additionally, the player can obtain a longsword with a crystal blade carved in the shape of the plasma envelope of the Energy Sword called "Hal's Sword". The name 'Hal' (obviously derived from 'Halo') is described in-game as the name the citizens of Albion gave to a mighty hero from another world. Also in the downloadable Knothole Island add-on, in the "Box of Secrets", the player can unlock 'a rare ranged weapon', "Hal's Rifle", which is an assault rifle.
 * In Halo: Combat Evolved, the Master Chief has the initials 'MLR' engraved below his MJOLNIR Mark V boot. This can be best seen in multi-player if a player stands on one another.
 * The MJOLNIR Mark VI was rated #13 in The 14 Most Badass Video Game Power Suits, a feature by Maxim.com.
