The '''MJOLNIR Powered Assault Armor/Mark VI''' was the third major version of the [[MJOLNIR Powered Assault Armor]]. The last mainline MJOLNIR GEN1 suit to be widely issued,{{Ref/Reuse|H4}} the Mark VI was issued to the few surviving [[SPARTAN-II program|Spartan-II supersoldiers]] in [[2552|October 2552]], replacing the [[Mark V]]. Shortly after the end of the [[Human-Covenant War]], it was replaced by the [[Mark VII]]{{Ref/Novel|Gla|Chapter=9}} and [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR [GEN2]]]. The Mark VI could still be requisitioned by [[SPARTAN-IV program|Spartan-IV]] personnel as late as [[2558|October 2558]], albeit upgraded to function with the GEN2 suite.{{Ref/Game|Id=H4|H4}}{{Ref/Game|Id=H5G|H5}} In early [[2559]], in the midst of the [[Created conflict]], the Mark VI armor has been upgraded to the [[MJOLNIR Powered Assault Armor (GEN3)|GEN3]] platform.{{Ref/Reuse|DH}}{{Ref/Marketing|Id=Step|HINF|Become|Step Inside}}

== Overview ==
Late into the war, as work on the MJOLNIR Mark V was being completed, a top-secret parallel development lab in [[Songnam]], [[Korea]], began work on their own prototype of Project: MJOLNIR. This project came to be known as [[MJOLNIR Powered Assault Armor/Black|MJOLNIR: BLACK]], a standalone "skunkworks" prototype of the Mark VI MJOLNIR armor.{{Ref/Anthology|Evo|Story=Blunt Instruments}} Using data from the existing and in-development versions of the MJOLNIR armor, the Seongnam team was able to produce a suit with many technical advancements not yet available to the standard Mjolnir system. After extensive testing of prototype models in combat against the Covenant, the BLACK prototype was eventually inducted into the Mjolnir line and officially designated as the sixth version.{{Ref/Book|Enc09|Page=89}} It was approved for use after the [[Fall of Reach|loss]] of [[Reach]] and equipped to the surviving Spartan-IIs after their arrival on Earth.

The Mark VI is capable of taking full advantage of the physical capabilities of a Spartan. The suit is constructed in overlapping layers. It is environmentally sealed, capable of [[extra-vehicular activity]] and operations in toxic atmosphere. It is hardened against [[electromagnetic pulse]]s and radiation, and has filters that are effective at removing toxins and bacteria from the local atmosphere.{{Ref/Book|Enc09|Page=92}}

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 number of impacts from Covenant energy weapons. 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 [[neural interface]].

[[File:H2A - MC face.jpg|thumb|250px|left|John-117 in his newly acquired set of Mark VI armor.]]

Spartans are implanted with a [[Spartan neural interface|unique model]] of the [[command neural interface]]. 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 use of weapons, and input from the onboard 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.

Each suit of Mjolnir Mark VI armor contains a layer of superconducting computer memory. Envisioned by Dr. [[Catherine Halsey]], this revolutionary layer forms a network, capable of supporting the kinds of artificial intelligence usually reserved for starships, a piggyback system.

The suits also contain a strength-enhancing layer.  This marvel of engineering uses piezoelectric properties to enhance and assist a Spartan's already prodigious muscle power, and grant superhuman feats of might.

The Mark VI largely solves problems with the previous versions of Mjolnir armor. It has an improved energy shielding system, powered by a smaller fusion pack on the wearer's back. This shield system is much stronger and charges more quickly than the Mark V's. The suit also has denser yet less bulky armor plating. These streamlined plates have fewer grapple points than the Mark V so that an enemy has fewer advantages in close combat.{{Ref/Book|Enc09|Page=90}}

In addition, the Mark VI's liquid crystal and hydrostatic gel layers received significant improvements over the previous version. The liquid crystal layer increases the strength of the wearer by a factor of five in addition to amplifying the user's reaction time by the same factor.{{Ref/Book|Enc09|Page=??}} The hydrostatic layer features a lock-down device, which protects the muscles and joints of its Spartan wearer from heavy-impact injuries.{{Ref/Book|Id=ENC91|Enc09|Page=91}}

In addition to major component upgrades the Mark VI introduces a number of smaller technical improvements to components. These included recoil-compensating actuators which handle weapon feedback. As a Spartan is firing a weapon in combat, these actuators handle a weapon's recoil reducing it without affecting the performance of the Spartan user. The Mark VI also possesses an improved computer system which continuously monitors weapons, biological functions, and motion through an intelligent [[motion tracker]].

The third stage in the MJOLNIR evolution, the Mjolnir Mark VI is a fully neural-linked system. With an onboard [[artificial intelligence]] using the human mind for parallel processing, the SPARTAN-II/MJOLNIR combination was the most devastating intelligence tool ever created.

==== Mark VI MOD ====
{{Main|Mark VI MOD}}
Referred to as Mark VI MOD,{{Ref/Reuse|MCMCC}} the Mark VI Mjolnir armor worn by MCPO [[John-117]] following the end of the Human-Covenant War was updated by UNSC AI [[Cortana]] during his four years and seven months of cryosleep aboard the {{UNSCShip|Forward Unto Dawn}}. Cortana used [[nanotechnology|minifacturing]] and diagnostic systems to repair and alter John's armor.

=== GEN2-related variants ===
Some Mark VI variants are superficially similar to the [[MJOLNIR Powered Assault Armor (GEN2)|GEN2 Mjolnir armor]] introduced in the wake of the [[Human-Covenant War]].<ref name="HWFred">[https://www.halowaypoint.com/en-us/universe/characters/frederic-104 ''Halo Waypoint'' - ''Frederic-104'']</ref> By [[2552#October|October 20, 2552]], [[Frederic-104]] and [[Linda-058]] had been issued prototype [[MJOLNIR Powered Assault Armor/Centurion|Centurion]] and [[MJOLNIR Powered Assault Armor/Argus|Argus]] variants, respectively. Both of these armors have a bodysuit similar to that of the GEN2 armor and they would stay superficially unchanged with the transition to the GEN2 platform.{{Ref/Game|H2A|Detail=''[[H2A:Terminals|Terminals]]''}} Fred and Linda received upgraded GEN2 versions of their suits in the post-war era, while [[Kelly-087]] donned the GEN2 [[HERMES-class Mjolnir|Hermes]] variant at some point after being rescued from the shield world [[Trevelyan]].

==== Mark VI GEN2 testing variant ====
This Mark VI looks similar to the hybrid GEN2/Mark VI [GEN1] armor, although it uses a slightly different techsuit from the mainline GEN2 armor.<ref>[https://www.instagram.com/p/y79tu0CRUW/?taken-by=hmcc_spartans ''Instagram'' - ''hmcc_spartans'']</ref>

=== GEN2 ===
==== Variants ====
Following the development of the GEN2 Mjolnir in the wake of the Human-Covenant War, the external components of the original Mark VI armor were reproduced as a variant of the new generation. This Mark VI incorporates slight modifications to accommodate the different base architecture of the GEN2 system.{{Ref/Reuse|H4}}{{Ref/Reuse|H5G}}
* '''Hybrid GEN2/Mark VI [Gen 1]'''
This variant of Mark VI uses many components from the base Mark VI as they have proven to be functional even after taking significant damage.{{Ref/Game|Id=H5G1|H5G|Armor customisation (Halo 5: Guardians)|Armory|Detail=Mark VI GEN1 Scarred helmet description|Quote=Constructed with the utmost care and multiply redundant subsystems, MARK VI helmets can remain functional even after horrendous damage. }}

===GEN3===
{{Quote|Hey Chief is that Mark VI armor? GEN3? Both? Neither? Does it have nanomachines?|A Marine during the [[Battle for Zeta Halo]].{{Ref/Game|Id=INF|HI|Marine dialogue}}}}
On February 10, 2559, the Materials Group manufactured a complete set of GEN3 Mark VI armor for [[John-117]].{{Ref/Marketing|Id=DH|HINF|Discover Hope}}<ref name="MCMCC">[https://www.youtube.com/watch?v=Le6WYZmWkDs MegaConstrux Master Chief Collection]</ref>{{Ref/Site|Id=CFDespite|URL=https://www.halowaypoint.com/en-us/news/despite-distance|Site=Halo Waypoint|Page=Canon Fodder - Distance Despite|D=31|M=08|Y=2020}} By October 7, this armor was also worn by [[Frederic-104]], [[Kelly-087]] and [[Linda-058]]. It looks aesthetically similar to a [[MJOLNIR Powered Assault Armor/Mark IV|MJOLNIR [GEN1] Mark IV]] armor variant they used during [[Operation: WARM BLANKET]]. By 2560, the GEN1 Mark VI shoulders and the GEN2 Mark VI MOD shoulders were both made by the Materials Group to be compatible with the GEN3 Mjolnir platform.{{Ref/Game|Id=HIMKVIGEN1|HINF|Armor customization (Halo Infinite)|Armor Hall|Detail=UA/Mark VI <nowiki>[GEN1]</nowiki> - Shoulders Description|Quote=Sometimes the best solutions are the ones that stand the test of time.}}

== Armor components ==
[[File:H4-MJOLNIR-Skinsuit.jpg|thumb|250px|The Mark VI skinsuit.]]
* '''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/Novel|Id=FoR3|FoR|Page=90}}
* '''Integrated communications helmet''':{{Ref/Game|H3|Armor customization (Halo 3)|Armory|Detail=Mjolnir Mark VI helmet description|Quote=Integrated Communications Helmet, Mjolnir: This standard-issue helmet for the Mjolnir Mark VI Powered Assault Armor has been in use since October 2552. It is compatible with all Mjolnir variants.}}{{Ref/Game|Id=armory|HR|Armor customization (Halo: Reach)|Armory|Detail=Mark VI helmet description|Quote=Data gathered from these field tests will be used to improve the final production model.}} The ICH is one of the most vital aspects of the MJOLNIR system. It is made of [[Titanium]], contains key features like a [[Heads Up Display]], 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's neural implants. Two core processor chips are implanted into the subject's skull at 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 helmet's on board sensors it creates the neural link needed to move the MJOLNIR suit. The helmet also contains equipment to protect the user in hostile conditions, such as filters to remove toxins from the atmosphere, an oxygen supply to provide air to the wearer during EVA, thermal and motion trackers, radio communicators, solar-powered lighting, and imaging and video gear. The helmet also contains an AI housing 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 damage, 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 wearer's life should the wearer be subjected to high G forces or a high velocity impact; however, over-pressurizing this layer can cause [[wikipedia:nitrogen embolism|nitrogen embolism]]s.{{Ref/Novel|FS|Page=13}}{{Ref/Novel|GoO|Chapter=1}}
* '''[[Polymerized lithium niobocene|Reactive metal liquid crystal layer]]''': Sandwiched between the external armor and the internal padding is a layer of piezoelectric material that deforms along a preferred axis when exposed to an electric charge. This layer acts as synthetic muscle, allowing the Spartan access to approximately five times their unarmored strength when using the Mark VI due to new optimization of the crystalline geometries.{{Ref/Reuse|H4EG}}{{Ref/Reuse|ENC91}}
* '''Memory-processor superconductor layer''': A layer relatively new to the Mjolnir line, introduced with the Mark V, that is capable of housing an AI. Comprised of the same material as a starship's AI system, this layer allows an 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/Novel|FoR|Page=286}}
* '''Magnetic weapon holder strips''': Powerful magnets are placed on the legs, waist, and back of the suit to hold any equipment with a magnetic property. The suit also contains a magnet 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 shielding#Human energy shielding|Energy shields]]''': First tested with the Mark IV, made standard with the Mark V, and later refined with the Mark VI, the energy shield device is reversed engineered from Covenant technology. Beginning prior to [[2531]], forty scientists and technicians would spend the next two decades 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.{{Ref/Novel|Id=for27|FoR|Chapter=27}}
* '''[[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.
* '''[[Biofoam|Automatic biofoam injectors]]''': Biofoam injectors are an integral part of the systems that 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.
* '''Fusion reactor''': The fusion reactor is the most essential part of the Mjolnir system, as it provides power to all equipment on the 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 battery pack used by Marines.{{Ref/Novel|FoR|Chapter=13}}{{Ref/Reuse|for27}}
* '''[[Force-multiplying circuit]]s''': 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 circuit]]s''': 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.
* '''[[MJOLNIR power supply control unit|Power supply control unit]]''': Manages the power supply of the armor.
* '''[[Mark VI BIOS|MJOLNIR Mark VI BIOS]]''': The basic input/output system, standard firmware interface for the Mark VI.
* '''Lock-down system''': The lock-down 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/Reuse|ENC91}}{{Ref/Level|Id=arrival|H3|H3:Arrival|Arrival}}{{Ref/Level|HR|Reach:Tip of the Spear|Tip of the Spear}}<ref>[https://www.youtube.com/watch?v=eLmtVh_bmhs ''Halo Reach Legendary Edition'' developer commentary, part 4]</ref>
* '''[[Quantum mirror]]''': A part of the armor's motion sensor system, located in the shoulder pauldron.{{Ref/Novel|GoO|Chapter=25}}
* '''[[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/Novel|FS|Chapter=34}}
