MJOLNIR Powered Assault Armor

The MJOLNIR (Pronunciation: ˈmjɔlˌnɪɹ 'my-all-'nhr) Powered Assault Armor is an advanced combat armor system designed to improve strength, speed, agility, reflexes, and protection of a Spartan-II supersoldier. It has seen many different iterations, ranging from the crude and primitive Mark I, II and III suits, to the first version to see deployment, the Mark IV, and later iterations that incorporated Covenant shielding systems, the Mark V and Mark VI. The MJLONIR system weighed at half a ton, near 1,000 pounds. Obviously, only genetic and cybernetic augmented soldiers, the Spartans, could wear the armor and use it to any degree.

Introduction
Created alongside the development of the Spartan II Program, MJOLNIR is the name of a series of Powered Armor suits designed to significantly improve the abilities of its wearer, giving superior physical strength, response time, velocity, and defensive capabilities. Originally designed only to protect its wearer from the projectile weaponry used by Insurrectionists, later variants, including the Mark V and Mark VI, would be equipped with an advanced personal energy shield reverse-engineered from captured Covenant technology. Between the external armor plating and the inner fabric suit is a layer of force-amplifying liquid crystal, used to increase speed, strength and reflexes.

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 linked to sensors in the gloves to detect the type of weapon held, and to project shield strength, ammunition count, a targeting reticule, waypoints, and other helpful data; a radio uplink for communication; and, with the Mark V and Mark VI variants, a layer of memory crystal capable of supporting a ship-grade artificial intelligence. The armor line is named for the mythical weapon Mjöllnir, the hammer of Thor, the Norse god of lightning, thunder, wind, and rain. This is the default armor for a multiplayer character. The origin of the word "Mjöllnir" 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 melt (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.

MJOLNIR is not the first attempt at creating a powered exoskeleton to enhance soldier's capabilities. Project HAYABUSA, a rival project, also created a powered armor boasting energy shields, though whether it saw actual combat is unknown. The Cyclops saw deployment on Harvest, though it was not originally intended for combat, and though powerful was also large, bulky, and unarmed other than brute strength. So far, MJOLNIR remains the most successful and well-known UNSC powered armor variant in history.

Mark I Prototype Exoskeleton
The Mark I Exoskeletons were one of the Navy's first experiments with powered exoskeletons. The Mark I battle armor were bulky exoskeletons that improved the strength and stamina of the user's muscles. A user could lift two tons (4,000 pounds) and run at 32 KPH (19.88 MPH). The armor was nearly impervious to standard light weapons. It could mount a 30mm mini-gun that fired on self-targeting armatures. It could also be equipped with motion sensors and infrared scopes. The armor used a hydraulic system for movement. The suit consumed enormous amounts of energy, so it required a connection to a fusion generator (which hindered movement) or the use of inefficient broadcast power, and was thus never seen in battle. It was, however, used to carry heavy equipment in docking bays, and dozens of others were dumped in Reach's titanium mines.

The Mark I Prototype Exoskeleton was also used for trainers to protect them when training Spartan IIs on Chief Petty Officer Mendez's orders. Otherwise, the training may have killed those trainers, as evidenced by SPARTAN-117's accidental killing of three ODSTs and severely injuring others aboard the UNSC Atlas during hand-to-hand combat. Dr. Halsey's team scrapped this concept and redesigned the battle armor from the ground up for Project: MJOLNIR. They used units of these that were not scrapped as dock loaders or to move heavy equipment. Some were even used for mining then thrown into storage on Reach.

Mark II Prototype
The Mark II battle armor incorporated a dramatically slimmed-down profile, but still required a tethered connection to a fusion reactor for power. Although the Mark II prototype had this flaw, it was the strongest type of armor in the entire human arsenal at the time.

Mark III Prototype
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 main reason being that the armor still had a limited operational range as it had to remain within range of a bulky, immobile generator, and second, the destruction of the generator would result in the incapacitation of the unit.

MJOLNIR Mark IV


Although the earlier attempts at developing high-powered armor produced designs that were impractical for battlefield deployment, this changed as soon as the directive came under Dr. Halsey's MJOLNIR Project. The Mark IV was a radical redesign of the suit taking advantage of many technological innovations. This battle suit was the first to feature full integration with the user's body. The suit plugged directly into the user's nervous system through a standard issue Neural Interface. The suit's many functions utilized the user's thoughts for commands, greatly speeding up the user's movements and reflexes. It's normal color is olive green, but there have been a few cases of gray armor such as the armor worn by Gray Team.

This was also the first design to successfully utilize the reactive metal liquid crystal as a means of enhancing locomotion. It enhanced the speed and power of the wearer, a sharp contrast to previous versions, which required powered motors to allow the user's mobility. Because of this advancement, the design more closely resembled an actual suit of armor, as opposed to a powered exoskeleton; the user moved the suit, and in return the suit moved the user. This allowed for an incredibly compact design when compared to the previous incarnations.

The success of this version was also dependent upon the parallel development of the Spartan-II program, which produced troops with the physical prowess required to drive the system. Previous attempts to wear the prototype suit by non-augmented troops resulted in their deaths or severe injury due to the extreme reactivity of the system.

The Mark IV armor contained an integrated computer system which continuously monitors weapons, biological function, and motion (through intelligent motion-sensing radar). It should be noted that the Mark IV did not have energy shields. The suit was airtight, hardened against vacuum, and featured air-filtration systems as well as a built-in re-breather that could last for up to 90 minutes. The suit's helmet also featured a standard UNSC mounted flashlight with its own separate power supply. This helmet seems nearly identical or at least very similar to the later Mark V helmet. Concealed side compartments in the upper thigh plates allowed the user to holster a sidearm.

The armor plates were specifically designed for combat with the Covenant. It resisted the Covenant's plasma-based weaponry extremely well; a Spartan soldier wearing the Mark IV could survive approximately three times as much damage from plasma weapons than an ODST could in full ballistic re-entry armor. The armor also provided almost complete immunity from ballistic firearms (though for gameplay reasons the Mark IV armor is prone to ballistic damage in the games--which are considered 'more' canon).

The suit also had a number of other features, including recoil-compensating actuators, hydrostatic gel (to regulate and monitor temperature and dampen impact force), and biofoam injectors. However, the biofoam injectors and medical care systems of the Mark IV had to be provided with a direct supply of biofoam, medicines, and stimulants from a standard Marine first aid kit when the user was injured, as the suit would not hold or generate a supply of medicines and biofoam, unlike the Mark VI.

The Mark IV Assault armor was fielded from November 27th, 2525 It was worn up to August 29th, 2552, when it was replaced by MJOLNIR Mark V armor. Strangely, the Mark-IV worn by the other SPARTAN-II's is different from that worn by Gray Team in color, which itself is gray. This is likely to differentiate them between the other SPARTAN's, considering this team stands out even among other SPARTAN-II's.

MJOLNIR Mark V
The newer Mark V replaced the Mark IV Assault Armor the day prior to the Covenant assault on Reach in 2552, though it was first produced in 2542. The Mark V was the realization of Dr. Halsey's vision. It had hundreds of minor technical improvements over the Mark IV as well as two major modifications. It could hold an Artificial Intelligence and had energy shields.

The Mark V was powered by a larger fusion pack than the Mark IV. This was necessary due to the fact that the Mark V had an integrated dynamic, self-recharging, energy shielding system, built using captured Covenant technology (similar to those used by Elites, but designed from captured Jackal energy shields) that repels mass objects and energy bursts. While impacts on the shield place a substantial drain on the system's power supply, the system's energy regenerates quickly once the user is no longer under fire. However, the process of adapting the shield to cover the entire body weakened the energy field, making the Mark V's shield system vulnerable to ballistic fire, unlike Jackal shields, which are near impervious to ballistic weaponry. This was unfortunate, as Flood Combat Forms frequently use UNSC weaponry. The armor was made up of layers of dense material and the outside was coated with an energy-absorbing coating. In addition, the Mark V featured a weave of memory-processor super-conducting material (the same material as an AI's core) beneath its armor. This gave the suit nearly the same capacity as a ship-borne AI system. This along with an upgrade to the standard-issue neural implant, allowed an AI to inhabit the suit of armor and interface with the mind of its user, greatly enhancing the interface between the suit and the wearer as well as boosting real-time data processing power, which was intended to assist the user in real-time by monitoring communication channels, computer relays, and friendly combat updates. The AI could translate thought into motion quickly, thus boosting the reaction time. Since without the armor, a SPARTAN's reaction time is charted at twenty milliseconds, the AI boost could render it almost instantaneous. The AI could "use" the person whose suit they were installed in literally as "memory." The AI can use some of the human's wet ware biological processing for some of its functions when installed in a Mark V or higher.

The Mark V is possibly the first model to have a Motion Tracker, with a range of 15 meters.

The MJOLNIR Mark V, along with its successor, the Mark VI, were equipped with magnetic pads placed throughout the suit, on the belt, thighs and back to hold weapons. LOTUS Anti-Tank Mines and HAVOK Nuclear warheads can also be held here when the Spartans are ordered to destroy a ship or base.

The lethality of this system was demonstrated by John-117, when he and the AI Cortana successfully fought their way across a planet-like, artificial ring-world called Halo.

Extra components were developed for the Mark V, to which the remnants of the Spartan II Red Team on Reach adapted to their armor. The helmet is featured as one of the many multi-player Armor Permutations in Halo 3. The chest is not available, but a very similar variant comes under the name EOD

John-117 was the first Spartan to test the MJOLNIR Mark V, during a training test he had to ring a bell by going through an obstacle course. This course involved 10 ODST troopers, LOTUS Anti-Tank Mines, three automated 0.30 caliber chainguns, a forest of wooden poles, and a SkyHawk Vtol Aircraft utilizing four 0.50 caliber cannons and Scorpion anti-tank missiles. This test showed that AI’s could improve the armor reacting times.

In addition, in Halo 3 multiplayer, the Mark V armor has been upgraded to be compatible with all Mark VI MJOLNIR armor.

MJOLNIR Mark VI
"Well, I guess it was all obsolete anyway. Your new suit's a Mark VI, just came up from Songnam this morning"

- Master Gunns

The Mark VI was first tested by Maria-062 in Songnam, Korea. She survived a battle against a squad of ODSTs, and after that the armor was approved for battle and was sent to John-117 in Cairo Station.

The Mark VI battle armor addressed some of the weaknesses of the earlier models. The energy shielding system recharged significantly faster and was notably stronger. The armor plating, while less bulky, was denser, therefore offering as much if not more protection than previous models. The suit was more streamlined than the Mark V, eliminating a number of grapple points that an enemy could use in close-quarters battle. This version of the armor could track the status of two active weapons at the same time, and also included a visual magnification system, allowing the user to see distant objects with ease.

There are anecdotal reports that during John-117's activities in the First Battle of Earth, an improved reactive metal liquid crystal layer had been developed for this suit, increasing the mobility of the Spartan even further, although this has yet to be confirmed. However, this claim may be reinforced by evidence such as faster melee attacks in Halo 2 Campaign, slightly faster jumping speed, and jump height. John-117's physical performance appeared to have improved considerably.

The armor was also capable of healing minor to moderate injuries over a course of time, due to an inboard supply of biofoam, which was automatically injected into the wearer's body, filling and sealing wounds, and numbing the pain. This new capability eliminated the need to manually apply a medkit or seek a field medic in order to tend to injuries. The biofoam effectively treats all but the most critical wounds, and its use was capable of stabilizing the user and allowing him to perform his duties even while injured until such a time as more extensive medical attention was possible. It is also likely that the suit was capable of automatically increasing the pressure level of its hydrostatic gel as the user was falling, explaining the lack of fall damage in Halo 2. According to the Halo 3 intro cinematic, the Mark VI also included a "lockdown" mode, where the suit retained a rigid form upon sustaining heavy trauma, most likely to avoid further injury. This explains the lack of a rag-doll animation when the player is flying through the air after being hit by a vehicle. However, other NPCs also have this animation, it usually occurs during melee or after getting caught in an explosion.

John-117 is the only confirmed active SPARTAN-II to receive the full Mark VI armor in game. Fred-104, Linda-058 and Will-043 may have been refitted with Mark VI armor once they returned to UNSC space after the events of Halo: First Strike.

The MJOLNIR is an adaptable suit of armor with many variations and modifications available, optimizing it for certain functions.

John-117's armor alters slightly graphically in between Halo 2 and Halo 3. These changes appear to be purely aesthetic in nature and have no canon explanation or reason.

This was also the first suit to contain Automatic Biofoam Injectors, which negated the need for Spartans to use Health Packs, which explains why there were no health bars in Halo 2 and Halo 3.

The Motion Tracker did not show a distance in Halo 2, although in Halo 3 it could see within a radius of 25 meters, so it is assumed the Mark VI has a 25 meter motion tracker.

Although a part of the MJOLNIR Mark VI Powered Armor series, the assumption that the Recon variant is only worn by Spartans is incorrect. Concept art for Halo 3: ODST released by Bungie has shown it in use by ODST reconnaissance operators, indicating that parts of the MJOLNIR series is being introduced, at least in extremely limited numbers, among the ODST Special Forces.

Armor Components

 * Luminous Green Refractive Titanium Alloy (External)
 * Matte Black Alloy (External)
 * Shields (Mk. V and Mk.VI only)
 * Hydrostatic Gel
 * Reactive Metal Liquid Crystal Layer
 * Pressure Seal
 * Automatic Biofoam Injectors (Mk. VI only)

Helmet
One of the most important parts of the MJOLNIR armor units was the MJOLNIR Helmet and Visor with its HUD. The helmet also had a small flashlight, which was useful in combat situations that are in poorly lit areas. It was solar-powered, recharging its energy from the sun when possible, or from the armor itself if necessary. Like the previous marks, the helmet of this armor features a small cap-like protrusion above the visor. This "cap" may serve to deflect rain from the visor, protect the visor should the wearer fall on his face, or serve to psychologically impact enemies.

Trivia

 * What looks like Mk V. or a prototype MJOLNIR armor can be seen on page 93 of the Halo Graphic Novel.
 * The armor seen on page 93 of the Halo Graphic Novel looks strikingly similar to Shi Kai Wang's preliminary sketch of Master Chief.
 * In both game manuals and in the books it is said that the armor weighs in at 1000 pounds, or a half-ton. However, in Halo 2, on the level Regret, the armor begins to float when the Master Chief jumps into a body of water. It has been stated that the armor has a feature that enables the suit to change its density which can be activated by the occupant and that automatically activates upon the user going unconscious. This would prevent Spartans from sinking to the bottom of an ocean and have to walk to shore to get out. Some other theories suggest that the hydrostatic gel keeps the suit afloat, or that the shields repel the water.
 * 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 one of the Bungie employee’s faces. It is possibly the face of Marcus Lehto, the Art Director.
 * Originally, the old design of the Mark V had an antenna on the shoulder. This is seen in the first Halo:Combat Evolved trailer.
 * The Mark V was given to the Spartan II's just before the invasion of Reach, and the Mark VI was given to them just before the invasion of Earth.
 * MJOLNIR has 7 letters in it.
 * The Cyclops in the upcoming game Halo Wars may be based on the Mark I-III.
 * 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 to be released in February of 2009, which will allow the Spartans to dual wield a weapon.
 * It is possible that the MJOLNIR powered armor contains a purification system, much like a very advanced water softener or a reverse osmosis pump, which allows Spartans to drink their own urine. Humans would still need water to survive, and it is unlikely to find good water to drink in a war, though it is more likely that they either have a canteen built in or at least on their person. Spartans probably do not need very much water, though, since one of their augmentations decreases lactic reactions in the muscles, which in turn would probably reduce the amount of thirst they would gain from battle.
 * The physical appearance of the Mark IV helmet previously seen in the first Halo Wars teaser was believed to have been scrapped due to the fact that the helmet looks more like the Mark V's helmet when it reappeared in the more recently released visuals for Halo Wars.
 * The Spartans in multiplayer for Halo 3 no longer feature the scratches that appeared on the Halo 2 Spartans.
 * The Limited Edition of the Xbox 360 action-RPG Fable II includes a set of Mjolnir armor for your 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. A picture of the armor with the sword, and the sword by itself can be seen here . The sword and armor feature the following in-game description: "Long ago, when Albion was still under the rule of the Old Kingdom, a rift in space opened a portal between dimensions. Through the rift stepped a warrior of immense power, clad in green armor and carrying a crystal sword. Though he never revealed his real name, he was known to all as Hal." In addition, the "Hal's Battle Armor" piece of the Hal's Armor outfit mentions that the chestplate saved Hal from the claws of a ghostly banshee, a play on the Covenant air vehicle of the same name.
 * In Halo: Combat Evolved, the Master Chief has the initials 'MLR' engraved below his MJOLNIR Mark V boot. This can be seen in multi-player if a player stands on another.
 * In Halo 1, 2, and Halo 3 Beta stages, the shields sprites hardly covered the visor on the Mark VI. In the final version of Halo 3, the shields for shoulder pieces and the visor are much smaller. The sizes of the sprites change when swapping different armor pieces.
 * You can remake the Mark IV armor in Halo 3 with the following combination: Helmet: Mark V, Shoulders: Security, Body: Mark VI or Recon, Emblem: Spartan, Primary and secondary colors: Green, Armor detail: red, Emblem primary: Sage, Emblem secondary: Red.
