The '''MJOLNIR Armor''' (Pronunciation: myôl'nir) is a heavy and complex suit of ground infantry [[armor]] of the [[United Nations Space Command]] designed to be worn by a [[Spartan II]].

== Introduction ==

It was designed by [[Dr. Catherine Halsey]] of the [[UNSC]] [[Office of Naval Intelligence]]<ref name="Sybex">[http://www.amazon.com/gp/reader/0782142362/ref=sib_dp_pt/104-1277807-1730301# Halo Bible Entry] on Page 5 of [[Halo: Combat Evolved: Sybex Official Strategies & Secrets|Halo: Combat Evolved: Strategies & Secrets]]</ref>. The armor has undergone several incarnations during the many years of its development. The suit is named for the mythical weapon Mjolnir. Mjolnir the hammer of the Aesir, Thor, the Norse god of lightning, thunder, wind, and rain. The origin for the word "Mjolnir" is unknown, though etymological speculation has provided theories for its literal translation. 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 as "lightning"). This second theory parallels with the idea that Thor, being a god of thunder, therefore might have used lightning as his weapon.

Dr. Halsey's decision to name what most would consider a defensive item after an offensive weapon tells much about her design philosophy for the project.

== Armor Versions ==

=== Mark I Prototype Exoskeleton ===

The Mark I battle suits were one of the Navy's first experiments with powered exoskeletons. The Mark I battle armors were bulky exoskeletons that improved strength and stamina of the user's muscles. A person in the suit can lift two tons (4,409 pounds) and run at 32 KPH (19.88 MPH). The armor is nearly impervious to standard light weapons. It could have a 30-millimeter minigun that fired on self-targeting armatures that had stun rounds for training and live bullets for actual combat. They could also be equipped with motion sensors and infrared scopes. The suit used a hydraulic system with hydraulic fluid which moved the suit. The suit consumed enormous energy, so it required a large cable to run between it and 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. Dr. Halsey's team had to scrap this concept and redesign the battle armor from the ground up for Project: MJOLNIR.<ref>[[Halo: The Fall of Reach]], page 70</ref>

=== Mark II PROTOTYPE ===

The Mark II battle armor incorporated a much more slimmed-down profile, but still required a direct link to a fusion reactor for power. Although the Mark II prototype has this flaw, it is the strongest type of armor in the entire human arsenal.

=== Mark III PROTOTYPE ===

The next prototype, the Mark III, incorporated a power transmission-receiver so that power could be transmitted to it much like the Orbital Defense Platforms in orbit of major UNSC colonies. This design was quickly rejected for two reasons, the main reason being that the armor still had a limited operational range, as the power generator could not be moved easily. The second reason was that if the generator was destroyed somehow, the users would become trapped in worthless, metal shells.
 
=== MJOLNIR Mark IV ===
[[Image:S11711.JPG|thumb|A Spartan in Mark IV armor]]Although the earlier attempts at developing powered-armor produced designs that were impractical for battlefield deployment, that changed as soon as the directive came under Dr. Halsey's MJOLNIR Project. The MJOLNIR Mark IV was a radical redesign of the suit taking advantage of many technological leaps. This advanced battle suit was the first to fully integrate with the soldier's body. The suit plugs directly into the soldier's nervous system through a standard issue [[Neural Interface]]. The suit's many functions (communications, hydro-static gel levels, environmental systems, etc.) respond to commands issued by the soldier's thoughts.<ref name="ceti">[[Halo: The Fall of Reach]], pages 114-117</ref>

This is also the first design to successfully utilize the reactive metal liquid crystal as a means of enhancing locomotion. It flawlessly enhances the speed and power of the wearer, a sharp contrast to previous versions which required powered motors to allow the soldiers mobility. Because of this advancement, the design more closely resembles an actual suit of armor, as opposed to a powered exoskeleton. On one level, the soldier moves the suit, and in return, the suit moves the soldier. This allowed for an incredibly compact design when compared to the previous incarnations.<ref name="ceti"/>

The success of this version was also dependent upon the parallel development of the [[Spartan-II]] program, which produced soldiers with the physical prowess required to drive the system. Previous attempts to wear the prototype suit by unaugmented soldiers resulted in their deaths or severe injury due to the extreme reactivity of the system.<ref name="ceti"/>

The MJOLNIR armor contains an integrated computer system which continuously monitors weapons, biological function, and motion (through an intelligent motion-sensing radar). It should be noted that the Mark IV did not have energy shields.<ref name="ceti"/>

The suit is air-tight, hardened against vacuum, and features air-filtration systems as well as a built-in oxygen supply that can last for up to 90 minutes. The suit's helmet also features a standard UNSC mounted flashlight with its own separate power supply. Concealed side compartments in the upper thigh plates allow the Spartan wearer to holster a sidearm.

The armor plates are specifically designed for combat with the Covenant.<ref name="ceti"/> It resists the [[Covenant]]'s plasma-based weaponry extremely well; a SPARTAN soldier wearing this armor can survive approximately three times as much damage from plasma weapons than an ordinary human Marine could. The armor also provides basic protection from human ballistic projectiles, although only to a slightly higher degree than regular Marine combat armor. The suit itself is practically indestructible and is capable of sustaining tremendous damage and still be able to function, but even though the suit will continue to operate, the human inside can still be injured or killed by a penetrating round or by sufficient plasma impacts to the suit's outer shell.

The suit also has a number of other features, including recoil-compensating actuators, hydrostatic gel (to regulate temperature and dampen impact force), and biofoam injectors. However, the biofoam injectors and medical care systems of the Mark IV must be provided with a direct supply of biofoam, medicines, and stimulants from a standard Marine first aid kit when the user is injured, as the suit will 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<ref>[[Halo: The Fall of Reach]], 113</ref> to August 29th, [[2552]].

=== MJOLNIR Mark V ===
[[Image:Chief.jpg|thumb|MJOLNIR Mark V]]
[[Image:SpartanMkV.jpg|right|thumb|200px]]
The Mark IV Assault Armor was replaced by the newer Mark V the day prior to the Covenant assault on Reach in 2552. The Mark V was the realization of Dr. Halsey's vision. It has hundreds of minor technical improvements over the Mark IV as well as two major modifications. 

The first is that it is powered by a slightly larger fusion pack than the Mark IV. This is due to the fact that the Mark V has an integrated dynamic, self-recharging, sophisticated energy shielding system, built upon 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, system energy regenerates quickly once the SPARTAN-II moves away from the barrage. However, adapting the shield to cover the entire body has weakened its energy field, making the Mark V vulnerable to ballistic fire, unlike the [[Jackal]] shields, which are near impervious to ballistic weaponry. This is unfortunate, as [[Flood]] [[Combat Forms]] frequently use UNSC weaponry.  



The second advancement is the addition of a weave of memory-processor super-conducting material, the same material as an AI's core. This gives the suit nearly the same capacity as a ship-borne AI system. This, along with an upgrade to the standard-issue neural implant, allows an AI to inhabit the suit of armor and the mind of the Spartan wearing it, greatly enhancing the interface between the suit and the wearer as well as the obvious benefits of having the incredible information processing power of an AI, which is intended to assist the Spartan in real-time by monitoring communication channels, computer relays, and friendly combat updates.

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

[[Image:MJOLNIR V armor V.jpg|thumb|right| Two Spartans in Mark V armor on [[Isolation (Level)|Isolation]]]]

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

It has been confirmed as one of the many multiplayer ''[[Armor Permutations]]'' in ''[[Halo 3]]''


==== MJOLNIR Mark V.5 ====

This is not an official name but has been used by some fans to describe modified MJOLNIR Mark V armor. Several Spartans upgrade their Mark V suits with Mark VI components over the course of the novel [[Halo: First Strike]]. Preferred upgrades were to the helmet design, shield system, leg armors, utility belt, and rubber undersuit (Hydrostatic Gel Layer), as well as fusion pack. Most armors, when upgraded, bear a resemblance to a Mark VI armor though not completely. Seeing that time was running short, Mark VI suits were not able to be mass produced, resulting in several Spartan's having to upgrade their armor instead of receiving a new Mark VI suit. 

However, in [[Halo: The Graphic Novel]], a full suit of MJOLNIR Mk. VI was field tested by [[Spartan-062]] (who retired from active duty to "Start a Family" before the events at Reach). This suit was later sent from its Proving Ground on Earth up to the Orbital MAC ([[Magnetic Accelerator Cannon]]) Station, Cairo, for use by Master Chief SPARTAN 117-John.

=== MJOLNIR Mark VI ===
[[Image:Master chief with 2 SMGS.jpg|left|thumb|MJOLNIR Mark VI]] [[Image:01mc.jpg|thumb|MJOLNIR Mark VI]]
The Mark VI of the MJOLNIR battle armor addresses some of the weaknesses of the earlier models. The energy shielding system recharges significantly faster and is notably stronger. The armor plating, while less bulky, is denser, therefore offering as much, if not more, protection than previous models. The suit is more streamlined than the Mark V. This version of the armor can now track the status of two active weapons at the same time.

It also appears from observation of Spartan John-117's performance during the 1st Battle for Earth that an improved reactive metal liquid crystal layer has been developed for this suit, increasing the mobility of the Spartan even further, although this has yet to be confirmed. However, this claim can be reinforced by such facts as faster melee attacks in Halo 2 Campaign, slightly faster jumping speed,and jump height. Spartan-117's physical performance appeared to have improved considerably.

Also, the armor can now heal minor to moderate injuries over a course of time, due to an onboard supply of biofoam, which is automatically injected into the wearer's body, filling and sealing wounds, and numbing the pain. This new capability eliminates 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, stabilizing the Spartan and allowing him to perform his duties, even while injured, until such a time as more extensive medical attention can be safely applied. It is also likely that the suit automatically increases the pressure level of its hydrostatic gel as the wearer is falling, explaining the lack of fall damage in the second game. According to the [[Halo 3]] into cinematic, the Mark VI also includes a "lockdown" mode, where the suit retains a rigid form upon sustaining heavy trauma, most likely to avoid further injury.

Spartan-117 is the only confirmed Spartan-II to receive the full Mark VI armor, due to budget restrictions. If you look at the Spartan in the backround of the cover of Ghosts of Onyx, the Spartan is wearing a Mark VI glove, not a Mark V glove. The same is true of the helmet that that Spartan is wearing. Both Spartans on the cover that are not wearing SPI (Semi Powered Infiltration) armor seem to not be wearing Mark VI armor; one is wearing what looks like upgrade Mark V armor, while the other is wearing non-upgraded Mark V armor, though this is only from what we can see on the cover, and there were three Spartan-II's that were not wearing SPI armor on Onyx in [[Ghosts of Onyx]], so this only accounts for two of those spartans. The Mark VI also appears to be an almost brown color in some Halo 3 media, although this is mainly when the Master Chief is in dry, desert-like regions and it could be due to dust or lighting (see image at top of page).

====[[Unknown Armor| Unknown Variant]]====
[[Image:753777342 19c07c569a o.jpg|right|150px|]]
An unknown armor has been seen on the Bungie Day art. Not much is known about it at the moment. It appears to be even more heavily armored, with a larger outer shell, possibly a "Heavy Weapons Variant" designed to take fire from heavy weapons and to use them. This is largely theoretical, based strictly on design.

{{Main|Heads Up Display}}
One of the most important parts of the MJOLNIR armor units is the MJOLNIR Helmet and Visor with its [[Heads Up Display|HUD]]. The helmet also has on the side a small recharging flood-light, which is useful in combat situations in poorly lit areas. It is solar-powered, recharging its energy from the sun when possible, or just from the MJOLNIR Combat Suit. The visor is also polarized so that one cannot see the wearer's face.

*"[[Wikipedia:Mjolnir|Mjolnir]]" (Mjølner in Norwegian, Mjölner in Swedish and Mjölnir in German) is the hammer-like weapon that the Norse thunder god [[Wikipedia:Thor|Thor]] uses to make lightning bolts by throwing it. 
*It has been comfirmed that the armor in [[Halo 3]] is still MJOLNIR Mark VI.
*[[343 Guilty Spark]] evaluates the Master Chief's Mark V armor as a "Type 2 Combat Skin", and comments that the Chief would be safer in a Type 12, implying that the [[Forerunners]] were capable of constructing defensive armor at least six times more powerful than MJOLNIR mark V.

-Created parallel to the [[SPARTAN-II program]] by the [[Office of Naval Intelligence]]'s [[Materials Group]], the Mjolnir armor is the most advanced piece of tactical military hardware in human hands. Each suit alone costs as much as a small starship. The brainchild of [[Catherine Halsey|Dr. Catherine Halsey]], MJOLNIR is an attempt to create a powered exoskeleton capable of taking full advantage of the physical capabilities of a Spartan.<ref name="sybex">'''Halo: Combat Evolved PC Strategy Guide''', ''page 5''</ref> MJOLNIR is considered by the [[Librarian]] to be the fulfillment of a millennia-old [[geas]] she had implanted in humanity a hundred millenia earlier, intended to help them [[Reclaimer|reclaim]] the [[Mantle]].<ref>'''Halo 4''', campaign level ''[[Reclaimer (level)|Reclaimer]]''</ref>
-Spanning over three decades of development, Project MJOLNIR encompassed more than just a suit of armor, but as a pioneering effort intended to shatter current technological barriers. In its final iteration, Mjolnir is a highly advanced suit capable of further enhancing the Spartans' physical performance while also doubling as a platform capable of handling an artificial intelligence network.<ref name="ENCY">'''[[Halo Encyclopedia (2009 edition)]]''', ''page 88''</ref>
+It was designed by [[Dr. Catherine Halsey]] of the [[UNSC]] [[Office of Naval Intelligence]]<ref name="Sybex">[http://www.amazon.com/gp/reader/0782142362/ref=sib_dp_pt/104-1277807-1730301# Halo Bible Entry] on Page 5 of [[Halo: Combat Evolved: Sybex Official Strategies & Secrets|Halo: Combat Evolved: Strategies & Secrets]]</ref>.

-The Mjolnir battlesuit's greatest advantage, however, is a super-dense optical computer memory. This revolutionary solid-based crystalline layer forms a network within the suit's frame of proper size and capability of housing the types of artificial intelligence usually reserved for starships. Essentially a piggyback system, an AI can be delivered to the suit via a [[data crystal chip]] storage device no larger than a personal credit card. The AI's personality and processing matrices can be carried by the armor and in conjunction with the user, can neurally link with a being that has nearly unfettered control over mathematics, information and body control. Such technology did not exist when work began on the Mark I prototypes.{{Ref/Reuse|xbox}}<ref name="ENCY2">'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 89''</ref>
+=== Mark I Prototype Exoskeleton ===
-The functionality of the Mjolnir system is unprecedented. Rather than being a traditional suit of body armor, the Mjolnir battlesuit works on a biomechanical level, allowing for direct user-controlled movement. Each human being has a molecular fiber network called the nervous system within their brain. Upon induction, all military personnel are issued a [[neural interface]], which is implanted at the base of the [[skull]] and cannot be removed.{{Ref/Reuse|xbox}}<ref>'''Halo: The Fall of Reach''', ''page 118'', (2001 edition) ''page 135'', (definitive edition) ''page 140'' (2010 edition)</ref> Spartan-IIs received a [[SPARTAN neural interface|modified]] version of the neural lace specifically for the Mjolnir armor.{{Ref/Reuse|xbox}} This neural lace, which consists of two core processor chips which is linked to receptors in the subject's brain, which is connected to an interface connection at the rear of the skull;{{Ref/Reuse|ENCY}} reads the electrochemical signals sent from the brain and then translates these chemical signals into digital code.{{Ref/Reuse|xbox}} As the electrochemical impulse travels down the axon to the muscle, the digital code is routed through the interface connection, to the suit's on board sensors, the input from the sensors is then read by the onboard computer and then like the human body itself sends an electrical impulse through the suit, as the impulse from the motor neuron hits the muscle, the electrical impulse from the suit causes the polymerized lithium niobecene to deform along a preferred axis, overlapping each other more, so that the layer gets shorter and fatter.{{Ref/Reuse|journal1}}<ref name="journaljul">'''Dr. Halsey's personal journal''' ''July 30, 2511''</ref> When the impulses from the suit stop, the polygonal pieces slide back to their original positions. At the same time, as the muscle fibers are responding to the impulses, signals are sent to the suit that this is occurring, as the muscle twitches the force being applied to the suit is accelerated through force-multiplying circuits, which amplify the force of the muscular twitch by a positive feedback loop in the armor. The end result is a fully neurally linked machine, the user's thoughts move the suit and in return the suit moves the user. The synthesis of machine and mind is so fast that it is almost impossible to chart reaction time.{{Ref/Reuse|FoR2}}{{Ref/Reuse|ENCY2}}
+The Mark I battle suits were one of the Navy's first experiments with powered exoskeletons. The Mark I battle armors were bulky exoskeletons that improved strength and stamina of the user's muscles. A person in the suit can lift two tons (4,409 pounds) and run at 32 KPH (19.88 MPH). The armor is nearly impervious to standard light weapons. It could have a 30-millimeter minigun that fired on self-targeting armatures that had stun rounds for training and live bullets for actual combat. They could also be equipped with motion sensors and infrared scopes. The suit used a hydraulic system with hydraulic fluid which moved the suit. The suit consumed enormous energy, so it required a large cable to run between it and a fusion generator, which hindered movement, or the use of inefficient broadcast power, and was thus never seen in battle.

-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 weapons and devices held, and to project shield strength, ammunition count, a [[Reticle|targeting reticle]], [[Navigation point|waypoints]], a [[COM|radio uplink]] for communication, health monitoring and restoration system, regenerative food materials and other helpful data.
+=== Mark II PROTOTYPE ===
-In its final phase, the Mjolnir battlesuit weighs half a short ton, or 1,000 pounds,<ref>'''Halo: The Fall of Reach''', ''page 2'', (2001 edition) ''page 3'', (definitive edition) ''page 16'' (2010 edition)</ref> and is a fully neural-linked system.

-==Armor generations==
+=== Mark III PROTOTYPE ===
-Before Dr. Halsey initiated Project MJOLNIR, the [[UNSC Navy]] had developed various designs and prototypes for powered exoskeletons and armour systems, including the [[Mark I prototype exoskeleton|Mark I exoskeleton]],<ref name="FoR3">'''Halo: The Fall of Reach''', ''page 71'', (2001 edition) ''page 81'', (definitive edition) ''page 90'' (2010 edition)</ref> the [[Mark III exoskeleton]],{{Ref/Book|Id=EVGCyclops|EVG|Pg=44}} [[ORION armor]],{{Ref/Site|Id=CF|URL=https://www.halowaypoint.com/en-us/news/anniversary-armory|Site=Halo Waypoint|Page=Canon Fodder - Anniversary Armory|D=03|M=11|Y=2021}} and [[HRUNTING Mark I exoskeleton|HRUNTING Mark I]].{{Ref/Reuse|journal1}} In [[2510]], Halsey inspected much of this previous work while performing a program review of [[Project HRUNTING]] on behalf of ONI. She judged HRUNTING to be an "interesting failure" for its lack of innovation, and inability to exploit recent technological breakthroughs.{{Ref/Book|Id=Enc22p77|Enc22|Page=77}} Later, during the early stages of planning for Project: MJOLNIR, Halsey would ultimately choose to start from scratch, due to both the limitations inherent in the previous antiquated designs,{{Ref/Reuse|journal1}}{{Ref/Reuse|FoR3}} and an unwillingless to shoulder the administrative burden of taking over and reforming an existing project such as HRUNTING. Instead, Halsey preferred to start fresh with an entirely new team, who were unbound by pre-existing dogma and assumptions about powered exoskeleton design.{{Ref/Reuse|Enc22p77}}
-The initial genesis of what would become Project: MJOLNIR can be traced back to as early as [[2511]]. By that year, Halsey was in communication with [[UNSC rank structure|Vice Admiral]] [[Michael Stanforth|Hieronymus Stanforth]] regarding the production of an armour system to complement the SPARTAN-II program, and had begun to brainstorm names for the project. In July, she penned an entry in her [[Dr. Halsey's personal journal|personal journal]] speculating that the [[Wikipedia:Piezoelectricity|reverse piezoelectric effect]] could be used to produce a bodysuit that enhanced the wearer's strength, by causing the suit to intelligently deform in response to the wearer's nerve impulses, adding extra force to their movements. This would become one of the defining features of MJOLNIR armour.{{Ref/Reuse|journal1}}
+The next prototype, the Mark III, incorporated a power transmission-receiver so that power could be transmitted to it much like the Orbital Defense Platforms in orbit of major UNSC colonies. This design was quickly rejected for two reasons, the main reason being that the armor still had a limited operational range, as the power generator could not be moved easily. The second reason was that if the generator was destroyed somehow, the users would become trapped in worthless, metal shells.
+=== MJOLNIR Mark IV ===
+[[Image:S11711.JPG|thumb|A Spartan in Mark IV armor]]Although the earlier attempts at developing powered-armor produced designs that were impractical for battlefield deployment, that changed as soon as the directive came under Dr. Halsey's MJOLNIR Project. The MJOLNIR Mark IV was a radical redesign of the suit taking advantage of many technological leaps. This advanced battle suit was the first to fully integrate with the soldier's body. The suit plugs directly into the soldier's nervous system through a standard issue [[Neural Interface]]. The suit's many functions (communications, hydro-static gel levels, environmental systems, etc.) respond to commands issued by the soldier's thoughts.<ref name="ceti">[[Halo: The Fall of Reach]], pages 114-117</ref>
-Work on Project: MJOLNIR would not begin in earnest for a further four years, however, with development beginning in [[2515]].{{Ref/Reuse|ENCY}} In that year, the project opened with a experimental phase, with a development platform that would be retroactively termed "Mark I" being used as a testbed for numerous trials and experiments over the following years.{{Ref/Reuse|Enc22p77}} The armour underwent significant iteration in the decade following, with at two further distinct prototype platforms emerging and forty prototype suits being produced across these three platforms, before the first production model - what would come to be known as Mark IV - was finalised. Mark IV was put into production in mid-[[2525]] and issued to the surviving SPARTAN-II candidates in November of that year.{{Ref/Reuse|FoR2}}{{Ref/Reuse|ENCY}}
+This is also the first design to successfully utilize the reactive metal liquid crystal as a means of enhancing locomotion. It flawlessly enhances the speed and power of the wearer, a sharp contrast to previous versions which required powered motors to allow the soldiers mobility. Because of this advancement, the design more closely resembles an actual suit of armor, as opposed to a powered exoskeleton. On one level, the soldier moves the suit, and in return, the suit moves the soldier. This allowed for an incredibly compact design when compared to the previous incarnations.<ref name="ceti"/>
-Initially, MJOLNIR was envisaged as an evolving platform, constantly and continuously updated with the latest technology as it became available. After a full decade, however, the Office of Naval Intelligence decided that it was no longer possible to facilitate this approach, much to Halsey's chagrin. In [[2535]], they mandated that MJOLNIR adopt a generational categorisation system, for the purposes of serialisation, prioritisation and progress-tracking, and as a means of fiscal oversight. Despite her reservations, Halsey agreed to the introduction of such a system, and produced a roadmap for future generations of the armour, in the hopes that it would "keep the accountants out of [her] hair and [her] work". The system devoted Marks I, II and III to prototype platforms produced between 2515 and 2525, while categorising all production models of MJOLNIR up until that point as Mark IV. Three further planned iterations, Marks V, VI and VII, were included in the roadmap, complete with rough technical specifications.<ref name="journal2">'''Dr. Halsey's personal journal''' ''January 7, 2535''</ref> Nevertheless, Halsey rarely used the "Mark" verbiage to describe the suits, due to her objections with its imposition by ONI.{{Ref/Reuse|Enc22p77}}
+The success of this version was also dependent upon the parallel development of the [[Spartan-II]] program, which produced soldiers with the physical prowess required to drive the system. Previous attempts to wear the prototype suit by unaugmented soldiers resulted in their deaths or severe injury due to the extreme reactivity of the system.<ref name="ceti"/>
-After the end of the Human-Covenant War, the Materials Group developed the second system-wide generation of MJOLNIR, simply designated GEN2, as a response to the SPARTAN-IV project. GEN2 is lighter than the Marks IV through VI and is far more modular than previous systems. The previous iterations of MJOLNIR were retroactively designated GEN1 to distinguish them from the GEN2.<ref name="O+A">[http://halo.xbox.com/halo4#!an-epic-universe/ordnance-armor/cbbca9b3-5108-41aa-aa21-9b523de68266 '''Halo 4''': ''ORDNANCE + ARMOR'']</ref><ref name="Gameplay">[http://halo.xbox.com/halo4#!halo-evolved/gameplay/31afe32b-0e07-45c0-9424-3adc6e1eadca '''Halo 4 Official Site:''' ''GAMEPLAY'']</ref>
+The MJOLNIR armor contains an integrated computer system which continuously monitors weapons, biological function, and motion (through an intelligent motion-sensing radar). It should be noted that the Mark IV did not have energy shields.<ref name="ceti"/>
-===Pre-production prototypes===
+The suit is air-tight, hardened against vacuum, and features air-filtration systems as well as a built-in oxygen supply that can last for up to 90 minutes. The suit's helmet also features a standard UNSC mounted flashlight with its own separate power supply. Concealed side compartments in the upper thigh plates allow the Spartan wearer to holster a sidearm.
-<!-- They should call this GEN0 in canon -->
-Before any generation of MJOLNIR made it into formal production, a full decade was spent in the research and development phase of the program. Three major distinct development platforms emerged over this period, which would be retroactively designated Mark I, II and III, with each successively refining and building upon the last. Across these three platforms,{{Ref/Note|Id=EncFortySuits|The 2009 and 2011 editions of the ''Halo Encyclopedia'' claim that these manufactured suits were of the Mark I generation specifically, and that they were later "scrapped" - suggesting an intention to actually put them into service. However, the 2022 edition of the Encyclopedia revises this claim, stating that the "at least forty" manufactured suits were of the Mark I, II and III platforms overall (not Mark I specifically), and establishes that they were only ever testbeds for experimentation, never production-ready suits of armour. Due to the recency of the 2022 edition, and the frequent inaccuracies in the 2009 and 2011 encyclopaediae, this article favours the 2022 edition.}} at least forty different physical suits were assembled, each to a varying stage of completeness with regards to systems integration and functionality. Suits from this prototypical generation of MJOLNIR were never intended to be put into service, instead serving merely as development platforms for Halsey and her team to iterate on.{{Ref/Reuse|Enc22p77}} Ultimately, the key failing of all three of these prototype platforms was the reliance on a local, external power source, requiring either a physical tether or for the user to remain within range of [[broadcast power]]. This made the designs impractical on the battlefield, as their range was severely limited by the lack of a mobile power source.{{Ref/Reuse|ENCY}}
-====Mark I====
+The armor plates are specifically designed for combat with the Covenant.<ref name="ceti"/> It resists the [[Covenant]]'s plasma-based weaponry extremely well; a SPARTAN soldier wearing this armor can survive approximately three times as much damage from plasma weapons than an ordinary human Marine could. The armor also provides basic protection from human ballistic projectiles, although only to a slightly higher degree than regular Marine combat armor. The suit itself is practically indestructible and is capable of sustaining tremendous damage and still be able to function, but even though the suit will continue to operate, the human inside can still be injured or killed by a penetrating round or by sufficient plasma impacts to the suit's outer shell.
-First developed in [[2515]], the Mark I was a development platform which served as a testbed for Halsey and her team to experiment with during the early stages of MJOLNIR development. Though bulky, unwieldy and difficult to control, the Mark I nevetherless pioneered the artificial muscles, embedded computer systems and control software that would become core to the MJOLNIR armour in later generations.{{Ref/Reuse|Enc22p77}} The suit also 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, though the suit did not possess the ability to carry an AI.{{Ref/Reuse|ENCY}} Despite these successes, the Mark I had one fatal flaw which would have to be overcome before MJOLNIR could ever be truly practical in the field: due to the tremendous amount of energy needed to power it, it had to remain physically tethered to a power source while in use.{{Ref/Reuse|ENCY}}{{Ref/Reuse|Enc22p77}}{{Ref/Note|The 2009 and 2011 editions of the ''Halo Encyclopedia'' also claim that the Mark I allowed the user to lift up to two tons (4,000 pounds) and run at 32&nbsp;km/h (19.88&nbsp;mph) for extended periods of time. However, these statistics were ascribed to the unrelated [[Mark I prototype exoskeleton]] by ''[[Halo: The Fall of Reach]]'', and misattributed to MJOLNIR Mark I by the ''Encyclopedia''. Thus, they are not listed on this article.}}
-Research and development for the Mark I was carried out at Section Three's headquarters inside [[CASTLE Base]] on [[Reach]], though the final assembly of components occurred at the [[Damascus Materials Testing Facility]] on [[Chi Ceti IV]]. The Mark I remained in development for a considerable amount of time before being succeeded by Mark II and later generations.{{Ref/Reuse|ENCY}}{{Ref/Note|The 2009 and 2011 editions of the ''Halo Encyclopedia'' state that it took a decade to develop the MJOLNIR Mark I. However, given that development of MJOLNIR only began in 2515, and that Mark IV was submitted to evaluation for mass production in February 2525, this would leave only 2 months for Mark II, III and IV to be produced. Given the implausibility of this, and the fact that the 2009 and 2011 ''Halo Encyclopediae'' are known to be frequently inaccurate, this article chooses to ignore this stated timeframe.}} Numerous Mark I suits were produced in various stages of completion, but as prototypes, they did not see use in battle.{{Ref/Reuse|ENCY}}{{Ref/Reuse|Enc22p77}}{{Ref/NoteReuse|EncFortySuits}}
+The suit also has a number of other features, including recoil-compensating actuators, hydrostatic gel (to regulate temperature and dampen impact force), and biofoam injectors. However, the biofoam injectors and medical care systems of the Mark IV must be provided with a direct supply of biofoam, medicines, and stimulants from a standard Marine first aid kit when the user is injured, as the suit will not hold or generate a supply of medicines and biofoam, unlike the Mark VI.
-====Mark II====
+The Mark IV Assault armor was fielded from November 27th, 2525<ref>[[Halo: The Fall of Reach]], 113</ref> to August 29th, [[2552]].
-A successor to Mark I, the Mark II platform was a refinement on the same basic system as the Mark I, which increased the suit's mobility and range.{{Ref/Reuse|Enc22p77}} This greatly improved mobility was enabled by the suit's slimmer profile. The Mark II also included a refractive coating to help disperse heat from explosions or directed energy weapons, and improved self-sealing systems in the event of damage while the unit was in a vacuum or an inhospitable atmosphere. However, the suit still needed to be physically tethered to a fusion generator, so despite being the most powerful piece of military hardware of its time, it was still impractical for battlefield deployment.{{Ref/Reuse|ENCY}}
-====Mark III====
+=== MJOLNIR Mark V ===
-Similar to the Mark II, the Mark III system was a further refinement on the same systems pioneered with the Mark I, and also featured increased mobility and range versus its predecessors.{{Ref/Reuse|Enc22p77}} Its major innovation, though, was that it was the first iteration to incorporate a wireless power receiver so that power could be transmitted directly to it, via [[broadcast power]]. This eliminated the need for a physical connection to the power source.{{Ref/Reuse|ENCY}}
+[[Image:Chief.jpg|thumb|MJOLNIR Mark V]]
+[[Image:SpartanMkV.jpg|right|thumb|200px]]
+The Mark IV Assault Armor was replaced by the newer Mark V the day prior to the Covenant assault on Reach in 2552. The Mark V was the realization of Dr. Halsey's vision. It has hundreds of minor technical improvements over the Mark IV as well as two major modifications.
-Though an improvement, this design was still quickly rejected, for two main reasons. First, the armor still had a limited operational range as it had to remain within range of a bulky, immobile [[generator]]. Second, if said generator was disabled or destroyed, the suit would become inoperable, leaving its user locked inside the now-inoperable shell, helpless against enemy attacks.{{Ref/Reuse|ENCY}}
+The first is that it is powered by a slightly larger fusion pack than the Mark IV. This is due to the fact that the Mark V has an integrated dynamic, self-recharging, sophisticated energy shielding system, built upon 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, system energy regenerates quickly once the SPARTAN-II moves away from the barrage. However, adapting the shield to cover the entire body has weakened its energy field, making the Mark V vulnerable to ballistic fire, unlike the [[Jackal]] shields, which are near impervious to ballistic weaponry. This is unfortunate, as [[Flood]] [[Combat Forms]] frequently use UNSC weaponry.
-===GEN1 - First generation===
-[[File:MarkIV model.jpg|thumb|The first iteration of the Mark IV Mjolnir platform]]
-After a decade of research and development, MJOLNIR would, in [[2525]], enter what retroactively became known as GEN1 - the first generation of MJOLNIR to be actively deployed in the field. This generation lasted throughout the [[Human-Covenant War]], and was described as "revolutionary, in both form and function". Over the course of the generation, the design would see significant iteration and refinement, with the addition of many notable upgrades, including personal [[energy shielding]] and the ability to host an on-board AI to assist the wearer.{{Ref/Book|Id=Enc22p78|Enc22|Page=78-79}} Nevertheless, GEN1 was not without its drawbacks: it required extremely complex manufacturing methods to create, and each suit had to be custom-tailored for its Spartan wearer.{{Ref/Book|Id=Enc22p80|Enc22|Page=80}}
-====Mark IV====
-{{Main|MJOLNIR Powered Assault Armor/Mark IV}}
-Despite the failure of the three earlier iterations of MJOLNIR, the MJOLNIR Mark IV armour would become the first MJOLNIR suit to see mass production and deployment onto the battlefield. Spearheaded by Dr. Catherine Halsey, the Mark IV was a radical redesign of the previous iterations. Most notably, it used an embedded miniature fusion reactor within the armour itself to power the suit, eliminating the cumbersome external generators that had plagued previous iterations. The MJOLNIR Mark IV armor was first fielded in November 27, 2525 and remained in service until November 24, 2551,<ref>[http://halo.bungie.net/News/content.aspx?type=topnews&link=BWU_012910 '''Bungie.net''': ''Bungie Weekly Update: 01.29.10'']</ref> though it received innumerable iterative upgrades in the interim.
-====Mark V====
+The second advancement is the addition of a weave of memory-processor super-conducting material, the same material as an AI's core. This gives the suit nearly the same capacity as a ship-borne AI system. This, along with an upgrade to the standard-issue neural implant, allows an AI to inhabit the suit of armor and the mind of the Spartan wearing it, greatly enhancing the interface between the suit and the wearer as well as the obvious benefits of having the incredible information processing power of an AI, which is intended to assist the Spartan in real-time by monitoring communication channels, computer relays, and friendly combat updates.
-{{Main|MJOLNIR Powered Assault Armor/Mark V}}
-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 [[artificial intelligence]] 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 from [[2551|November 24, 2551]] to [[2552#October|October 20, 2552]].
-====Black====
+The MJOLNIR Mark V and VI are equipped with magnetic pads placed throughout the suit, on the belt, thighs and back. LOTUS Anti-Tank Mines and HAVOK Nukes can be held here when the Spartans are ordered to destroy a ship or base.
-{{Main|MJOLNIR Powered Assault Armor/Black}}
-Created by a top-secret parallel development lab in [[Seongnam]], [[Korea]], MJOLNIR: Black was a standalone "skunkworks" prototype of the Mark VI issued exclusively for [[Team Black]]. It features a number of advances over contemporary Mjolnir exoskeletons. It was used on [[Raid on Verge|Verge]] during the Covenant invasion of the [[Epsilon Eridani system]] and during [[Operation: BLOWBACK]] some time after.
-====Mark VI====
+[[Image:MJOLNIR V armor V.jpg|thumb|right| Two Spartans in Mark V armor on [[Isolation (Level)|Isolation]]]]
-{{Main|MJOLNIR Powered Assault Armor/Mark VI}}
-The Mjolnir Mark VI is the third primary version of the system. It 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 to jump higher, run faster, and hit harder than a Spartan could previously.
-====Mark VII====
+The lethality of this system was demonstrated by Spartan-117, also known as "John", "John-117", or Master Chief, when he and the AI Cortana successfully fought their way across a planet-like, artificial ring world called Halo.
-{{Main|MJOLNIR Powered Assault Armor/Mark VII}}
-The Mark VII is the fourth major iteration of the Mjolnir armor introduced in [[2553|January 2553]]. It is lighter than the previous first-generation suits,<ref>'''Halo: Glasslands''', ''page 291''</ref> with new features including limited energy shield shaping and a nanotechnology repair suite. Ultimately, the Mark VII was never widely issued as it was deemed too complex and expensive for mass-production, particularly in light of the development of the more versatile GEN2 platform which enabled more economical optimization for the different Spartan generations in service, while the first generation was mainly optimized for the Spartan-IIs.<ref name="wp mjolnir">[https://www.halowaypoint.com/en-us/universe/tech/mjolnir '''Halo Waypoint''': ''MJOLNIR'']</ref>

-Generation 2 Mjolnir [GEN2] is a program-wide overhaul of the system primarily developed for the Spartan-IVs.{{Ref/Reuse|wp mjolnir}} Its most notable feature is the radical streamlining of the exoskeleton architecture, with the number of complex components reduced by an order of magnitude in comparison to GEN1 suits.<ref name="HOSFM">''[[Halo: Official Spartan Field Manual]]'', pg. 178-179</ref> The GEN2's design philosophy is geared toward integrating the vast majority of the armor's vital hardware into the bodysuit, known as a techsuit, enabling more streamlined production and easier implementation of specialized components.{{Ref/Reuse|wp mjolnir}} However, this sacrifices some of the suit's efficiency, and the performance improvements over GEN1 Mjolnir are minimal.{{Ref/Reuse|HOSFM}} The second generation uses a spiral-development model of production, enabling the UNSC and its corporate partners to iterate on the armor systems much faster and more efficiently than with the first generation.{{Ref/Reuse|wp mjolnir}} GEN2 is produced by half a dozen manufacturers, both within the military and among private contractors.{{Ref/Reuse|O+A}}{{Ref/Reuse|Gameplay}} It is equipped with new ''ad hoc'' modification systems which gives the armor the ability to use tactical packages, support upgrades, and armor abilities.{{Ref/Reuse|O+A}}{{Ref/Reuse|Gameplay}}

-===GEN3 - Third generation===
+==== MJOLNIR Mark V.5 ====
-{{Main|MJOLNIR Powered Assault Armor (GEN3)}}
-MJOLNIR GEN3 is the third generation of Mjolnir armor, incorporating lessons learned from GEN2 line of Mjolnir, while also seeking to restore some of the favorable design characteristics and materials of the GEN1 line.{{Ref/Book|Id=Enc22p85|Enc22|Page=85}} GEN1 Mark VII was used as the testbed for GEN3 improvements and when GEN3 Mjolnir began to be produced in [[2559#February|February 2559]],{{Ref/Reuse|HOSFM}}{{Ref/Generic|Id=DH|[[Discover Hope]]}} Mark VII would for the first time receive a full production run.{{Ref/Site|Id=CFDespite|D=30|M=3|Y=2023|URL=https://www.halowaypoint.com/en-us/news/despite-distance|Site=Halo Waypoint|Page=Canon Fodder - Despite Distance}} GEN3 introduced numerous upgrades when compared to the GEN2 platform, including enhanced energy shielding capabilities, a more compact and efficient fusion reactor, and variable-density hydrostatic gel dispersal membranes. While GEN3 did increase the overall use of exotic composites, several innovations in the manufacturing process and a refinement of the platform's modularity have resulted in a suit of armor that is more cost-effective and versatile than both previous generations.{{Ref/Reuse|Enc22p85}} By [[2559#October|October 2559]], GEN3 Mjolnir armor would become the standard armor generation fielded by Spartans,{{Ref/Novel|Id=SOR2|SoR|Chapter 16}} though other armor systems such as the GEN1 [[B-class Mjolnir|Mark V[B]]] platform and its variants have been upgraded to be roughly equivalent to GEN3 Mjolnir, offering Spartans greater choice in the Mjolnir they field.{{Ref/Site|Id=CFParallel|URL=https://www.halowaypoint.com/en-us/news/parallel-threads|Site=Halo Waypoint|Page=Canon Fodder - Parallel Threads|D=30|M=3|Y=2023}}
-==Armor components==
+This is not an official name but has been used by some fans to describe modified MJOLNIR Mark V armor. Several Spartans upgrade their Mark V suits with Mark VI components over the course of the novel [[Halo: First Strike]]. Preferred upgrades were to the helmet design, shield system, leg armors, utility belt, and rubber undersuit (Hydrostatic Gel Layer), as well as fusion pack. Most armors, when upgraded, bear a resemblance to a Mark VI armor though not completely. Seeing that time was running short, Mark VI suits were not able to be mass produced, resulting in several Spartan's having to upgrade their armor instead of receiving a new Mark VI suit.
-===Inner components===
-*'''Inner skinsuit:'''
-The inner skinsuit is made of a moisture-absorbing synthetic material linked to an environmental control computer and the occupant's neural interface. It controls the suit's temperature and actively changes how the suit fits the user.{{Ref/Reuse|FoR3}}
-*'''[[Hydrostatic gel]]:'''
+However, in [[Halo: The Graphic Novel]], a full suit of MJOLNIR Mk. VI was field tested by [[Spartan-062]] (who retired from active duty to "Start a Family" before the events at Reach). This suit was later sent from its Proving Ground on Earth up to the Orbital MAC ([[Magnetic Accelerator Cannon]]) Station, Cairo, for use by Master Chief SPARTAN 117-John.
-On top of the inner skinsuit is a gel-filled layer, which regulates the temperature of the suit and can 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, overpressurizing this layer can cause nitrogen embolisms.<ref>'''Halo: First Strike''' ''page 13'' ''page 20'' (2010 edition)</ref><ref>'''Halo: Ghosts of Onyx''' ''page 36''</ref>
-*'''[[Polymerized lithium niobocene|Liquid metal crystal piezoelectric layer]]:'''
+=== MJOLNIR Mark VI ===
-The inner structure of the suit{{Ref/Book|Id=encyc91|[[Halo Encyclopedia (2011 edition)]]|Section=Project: MJOLNIR|Page=91}} is a layer of piezoelectric liquid crystal that deforms along a preferred axis when exposed to an electric charge.{{Ref/Reuse|journaljul}} This layer acts as a sheath or a suit of artificial muscle; this reactive piezoelectric effect increases the mobility, speed, and all-around physical performance of the suit's user,{{Ref/Reuse|journaljul}} doubling their strength and increasing the reaction time of the user by a multiple of five. The material is amorphous, which circumvents a major obstacle in its design: custom fitting millions of the polygonal pieces under the second armor layer.{{Ref/Reuse|journalsep}} Knitted together at a molecular level the liquid crystal material is merely "poured" into a multilayered Sierpinski capillary system where microelectric fields can direct crystallization geometries.{{Ref/Reuse|journalsep}} The only downfall is the material's production, which involves classified super-toxic precursor materials and requires a zero-gravity environment.{{Ref/Reuse|journalsep}}
+[[Image:Master chief with 2 SMGS.jpg|left|thumb|MJOLNIR Mark VI]] [[Image:01mc.jpg|thumb|MJOLNIR Mark VI]]
+The Mark VI of the MJOLNIR battle armor addresses some of the weaknesses of the earlier models. The energy shielding system recharges significantly faster and is notably stronger. The armor plating, while less bulky, is denser, therefore offering as much, if not more, protection than previous models. The suit is more streamlined than the Mark V. This version of the armor can now track the status of two active weapons at the same time.
-This makes hand-to-hand combat easier, but also makes 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 the armor, as their strengthened muscles and bones are able to withstand the increased power and speed of movement. In unaugmented human bodies, a simple flex results in the system returning a reactive backlash that breaks bones and tears muscles, causing the cascade of agony-induced muscle spasms to be further inflicted back onto the wearer, killing them in seconds.
+It also appears from observation of Spartan John-117's performance during the 1st Battle for Earth that an improved reactive metal liquid crystal layer has been developed for this suit, increasing the mobility of the Spartan even further, although this has yet to be confirmed. However, this claim can be reinforced by such facts as faster melee attacks in Halo 2 Campaign, slightly faster jumping speed,and jump height. Spartan-117's physical performance appeared to have improved considerably.
-*'''Knitted-crystal computer memory layer'''
+Also, the armor can now heal minor to moderate injuries over a course of time, due to an onboard supply of biofoam, which is automatically injected into the wearer's body, filling and sealing wounds, and numbing the pain. This new capability eliminates 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, stabilizing the Spartan and allowing him to perform his duties, even while injured, until such a time as more extensive medical attention can be safely applied. It is also likely that the suit automatically increases the pressure level of its hydrostatic gel as the wearer is falling, explaining the lack of fall damage in the second game. According to the [[Halo 3]] into cinematic, the Mark VI also includes a "lockdown" mode, where the suit retains a rigid form upon sustaining heavy trauma, most likely to avoid further injury.
-Fitted in between the outer plates and the inner padding, is a crystal computer memory layer. It is knitted at the molecular level and supports the integration of [[Artificial intelligence]]. This type of memory is most often seen on [[Human starship|ships]] and represents 80% of the cost of the suit.{{Ref/Reuse|encyc91}} This layer was present in at least one [[MJOLNIR Powered Assault Armor/Mark V|Mark V]] suit,{{Ref/Novel|FS|Chapter=7}} and likely in at least one Mark VI suit.{{Ref/Note|The image used to illustrate this information in the Encyclopedia is that of the Mark VI. Whether this layer was widely used across all versions of either generation is unknown as Master Chief thus far is the only known Spartan-AI instance.}}
-*'''[[Pressure seal]]:'''
+Spartan-117 is the only confirmed Spartan-II to receive the full Mark VI armor, due to budget restrictions. If you look at the Spartan in the backround of the cover of Ghosts of Onyx, the Spartan is wearing a Mark VI glove, not a Mark V glove. The same is true of the helmet that that Spartan is wearing. Both Spartans on the cover that are not wearing SPI (Semi Powered Infiltration) armor seem to not be wearing Mark VI armor; one is wearing what looks like upgrade Mark V armor, while the other is wearing non-upgraded Mark V armor, though this is only from what we can see on the cover, and there were three Spartan-II's that were not wearing SPI armor on Onyx in [[Ghosts of Onyx]], so this only accounts for two of those spartans. The Mark VI also appears to be an almost brown color in some Halo 3 media, although this is mainly when the Master Chief is in dry, desert-like regions and it could be due to dust or lighting (see image at top of page).
-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 but will only break under extreme pressure, such as in a high velocity impact or when the hydrostatic gel has been overpressurized.<ref>'''[[Halo: First Strike]]''', ''page 19'', ''page 31'' (2010 edition)</ref>
-*'''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.<ref name="ENCY3">'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 90''</ref>
+It was developed by the [[United Nations Space Command]] in the [[Beweglichrüstungsysteme]] facility [[Essen]] and specialized to "improve survivability in close combat" for the [[SPARTAN-II]] supersoldiers by "looking at alternate methods of K dispersal and improving joint mobility".

-Known to be present in the Mark V<ref>'''Halo: First Strike''', ''page 244'' (2003)</ref> and VI generations, biofoam injectors are 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.
+[[Image:MJOLNIR Mk.VI Powered Assault Armor (EVA).jpg|200px|right]]

+An unknown armor has been seen on the Bungie Day art. Not much is known about it at the moment. It appears to be even more heavily armored, with a larger outer shell, possibly a "Heavy Weapons Variant" designed to take fire from heavy weapons and to use them. This is largely theoretical, based strictly on design.
-*'''Lockdown system''':
+{{clear}}
-The lockdown system protects muscles and joints from traumatic, high-impact injuries by seizing the suit into a rigid posture through modifying the density of the hydrostatic gel layer.<ref>''Halo 3'', level ''[[Arrival]]''</ref><ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 91''</ref><ref>'''Halo: Reach''', level ''[[Tip of the Spear]]''</ref>
-===Outer components===
-*'''Integrated communications helmet:'''
-The Mjolnir helmet is one of the most vital aspects to the MJOLNIR armor system. It is made of [[titanium]] and features 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. An environmental control unit that includes filters to remove toxins from the atmosphere, and a rebreather to automatically supply oxygen to the wearer during EVA. In addition the helmet is packed with thermal and motion sensors, communications, solar-powered lighting, and imaging and video gear.
-The most important feature though, is the direct neural interface system which connects to a Spartan's 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 subject's head and receptors in the brain link to the helmets on board sensors it creates the neural link needed to move the MJOLNIR suit.{{Ref/Reuse|ENCY}}
-*'''Titanium alloy outer shell''':
+{{MJOLNIR_Variations}}
-The outer shell of the Mjolnir armor is composed 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 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.{{Ref/Reuse|ENCY3}}
-*'''Memory processor superconductor layer''':
+== Armor Components ==
-Introduced with the Mark V, this layer allows a starship-grade AI to travel with a soldier into the field. The AI can then aid the soldier in software intrusion, hardware hacking, and espionage by listening to enemy chatter.<ref>'''Halo: The Fall of Reach''', ''page 252'', (2001 edition) ''page 292'', (definitive edition) ''page 286'' (2010 edition)</ref>
-*'''Magnetic weapon holder strips''':
+*Luminous Green Refractive Titanium Alloy (External)
-These 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.
+*Matte Black Alloy (External)

-*'''[[Energy shielding#Human energy shielding|Energy shield system]]''':
+=== Helmet ===
-Unsuccessfully tested with the Mark IV,<ref>'''Halo: The Essential Visual Guide''', ''page 119'': ''"Energy shielding was a key feature of Mark V, although other Spartan squads had field-tested prototypes of this technology as early as 2531."'' The Grenadier variant, introduced four years later, also served as a test bed for energy shielding.</ref> properly introduced with the Mark V, and later refined with the Mark VI, the energy shield device is reversed engineered from Covenant technology. In 2532,{{Ref/Reuse|ENCY2}} 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 in the late 2540s a breakthrough was made and for the first time the UNSC had successfully cracked and improved upon the technology.<ref>'''Halo: The Fall of Reach''', ''page 249'' (2001 edition) ''page 289'', (definitive edition) ''page 283-284'' (2010 edition)</ref>
+{{Main|Heads Up Display}}
+One of the most important parts of the MJOLNIR armor units is the MJOLNIR Helmet and Visor with its [[Heads Up Display|HUD]]. The helmet also has on the side a small recharging flood-light, which is useful in combat situations in poorly lit areas. It is solar-powered, recharging its energy from the sun when possible, or just from the MJOLNIR Combat Suit. The visor is also polarized so that one cannot see the wearer's face.
-*'''Power plant:'''
+== Marathon Reference ==
-Integrated into the final production model of the Mark IV in 2531, the microfusion cell is the most vital component to the Mjolnir system, as it provides power to all components of the armor. The reactor is built into the suit and allows for nearly unlimited power. The fusion reactor is half the size of a normal battery pack.<ref>'''Halo: The Fall of Reach''', ''page 114'', (2001 edition) ''page 131'' (definitive edition) ''page 137'' (2010 edition)</ref> Pre-2531 versions of the armor use a [[nuclear fission]] reactor as a source of power. However, because of the delicacy and radioactive nature of the fission reactor its use was limited until it was replaced with a fusion plant in the final production model of the Mark IV.{{Ref/Reuse|journal2}}<ref>'''Halo: Ghosts of Onyx''' ''page 45''</ref>
-*'''[[MJOLNIR power supply control unit|Power supply control unit]]''':
+The player in Marathon is speculated to be one of the Mjolnir Mk. IV cyborgs that are referred to in terminals throughout the game.
-The power supply control unit controls the power supply of the armor.
-*'''[[Fail-safe detonation system]]''':
-This system functions as a self-destruct mechanism in order to prevent a dead Spartan's armor from being compromised by hostiles. It is activated by a series of digits that only the Spartans know. When engaged, it produces a reactor overload that burns everything within a ten-meter radius, then produces a large blast.<ref>'''Halo: First Strike''', ''page 315'', ''page 377'' (2010 edition)</ref>

-==Trivia==
-*Out-of-universe, MJOLNIR armor takes its name and designation scheme from [[Bungie]]'s earlier ''[[Marathon]]'' series, in which the [[marathongame:Mjolnir Recon number 54|player character]] is a Mjolnir Mark IV "battleroid" cyborg.
-*The Limited Edition of the Xbox 360 action RPG ''[[Wikipedia:Fable II|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 [[John-117|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]].
