MJOLNIR Powered Assault Armor/Mark VI
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, the Mark VI was issued to the few surviving Spartan-II supersoldiers in October 2552, replacing the Mark V. Shortly after the end of the Human-Covenant War, it was replaced by the Mark VII and MJOLNIR [GEN2]. The Mark VI could still be requisitioned by Spartan-IV personnel as late as October 2558, albeit upgraded to function with the GEN2 suite.
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: BLACK, a standalone "skunkworks" prototype of the Mark VI MJOLNIR armor. 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. It was approved for use after the 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 pulses and radiation, and has filters that are effective at removing toxins and bacteria from the local atmosphere.
The armor's shell is composed of a multilayer alloy of remarkable strength and has been augmented with a refractive coating capable of dispersing a limited 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.
Spartans are implanted with a 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.
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. The hydrostatic layer features a lock-down device, which protects the muscles and joints of its Spartan wearer from heavy-impact injuries.
In addition to major component upgrades the Mark VI introduce 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 weapons 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 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.
Variants and compatibility
Mark V prototype
Being a modular armor system, Mjolnir can fulfill multiple combat roles and operate in various environments. A number of variants have been designed for to meet the mission requirements and situations. These variants are the pinnacle of Mjolnir evolution from design and function gathered from data, feedback, incidents and general design improvements gather throughout the Human-Covenant War.
Mark V upgrade
In 2552, the Mark V helmet received an upgrade to Mark VI with then current-issue internal components and software.
John-117's upgraded Mark VI
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 UNSC Forward Unto Dawn. Cortana used minifacturing and diagnostic systems to repair and alter John's armor. This armor closely resembles an earlier line of Mark IV armor. She also rewrote the suit's firmware, altering the HUD as well as improving the suit's shield recharge rate and its compatibility with Covenant and Forerunner armor plugins. This armor was damaged during the Skirmish on Installation 03 and replaced by a similar GEN2 Mjolnir armor variant.
Some Mark VI variants are superficially similar to the GEN2 Mjolnir armor introduced in the wake of the Human-Covenant War. By October 20, 2552, Frederic-104 and Linda-058 had been issued prototype Centurion and 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. Fred and Linda received upgraded GEN2 versions of their suits in the post-war era, while Kelly-087 donned the GEN2 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.
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.
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.
This variant of Mark VI keeps all the designs of the original Mark VI armor, but has been completely updated to modern powered assault armor standards. This variant has a classic GEN1 heads-up display, a solid collar frame and branch locking system. It is also equipped with a Class-3B Essen shield distributor. The Ordnance Commission allowed this variant to be used due to the original Mark VI's performance.
Performance and durability
The Mark VI armor was the culmination of decades of research and re-engineering its predecessors, Mark IV and Mark V. This armor was not only more condensed than its previous iterations, but it was also much more durable.
While stranded on Line Installation 1-4, a Mark VI prototype worn by a member of Black Team was able to withstand being punched in to a Forerunner terminal by a Mgalekgolo and keep its wearer completely intact in the process.
On-board the bow of the UNSC Forward Unto Dawn's bisected wreckage, John launched a Hyperion nuclear missile into the hull of an unshielded CRS-class light cruiser in response to the Covenant remnants attack on the Dawn. With his MJOLNIR's strength-multiplying circuits, John was strong enough to re-activate the hammer's seized sliding apparatus by overwhelming the jam's heavy traction simply by shoving and then kicking it into place.
Subsequent to the Ur-Didact's awakening, and during the destruction of Requiem's core, John's MJOLNIR-donned frame was cratered several meters deep into non-porous, rocky terrain. The armor proved strong enough to resist the blunt-force trauma of such an impact with no visible damage - at the minor expense of an interim concussion.

Halo 2 and Halo 3
John-117 wears a Mark VI suit throughout the campaigns of Halo 2 and Halo 3. The Mark VI armor experienced minor graphical changes between these two games, most notably in the design of the gauntlets. The colors are more muted, with the armor bearing a gray hue. The general shape of the HUD is the same. However the radar is slightly larger and the ammo and grenade counters are no longer enclosed in templates. The most obvious difference is that the shield meter has been relocated from above the radar to the top-center of the HUD. Additionally the radar has a radius reading, with a default 25 meters. These changes appear to be purely aesthetic in nature and have no canonical explanation, though the discoloration could be due to extended and rigorous use and the HUD changes could simply be updates.
The Mark VI helmet appears in Halo: Reach as a prototype, possibly MJOLNIR: Black variant. Two upgrades are available for the helmet, the first of which adds a Command Network Module on the left side with a Hardened Uplink Module-3rd Generation on the right side (FC-I). The second upgrade adds an up-armor plate with a Command Network Module-Improved on the right side. The top part of the helmet has a single white stripe painted down the middle. Additionally, the sun visor is colored solid black.
Halo 4 and Halo 5: Guardians
John-117 continues to wear his original Mark VI suit in Halo 4's campaign, although it has been redesigned. In an interview with Game Informer, Frank O'Connor offhandedly mentioned that Cortana used nanomachines to repair the suit; In Halo 4, the suit still has the gash it has featured since Halo 3 as it was not repaired, apparently because that area suffered irreparable damage. Halo 4: The Essential Visual Guide notes that Cortana fully updated the suit, and that it resembles an earlier line of the Mark IV.
John's armor in Halo 5: Guardians is largely identical to its appearance in Halo 4, barring minor cosmetic updates. The faceplate has been changed from a dull shade of orange to the vibrant gold of earlier titles. The formerly gashed chestplate is now intact. The undersuit's snakeskin texture is now limited to the arms and upper torso; the rest of the undersuit is smooth, with the waist and legs sporting a subtle digital camouflage pattern. Red piping is painted around the fusion pack's vents, although in the final release of the game, the red piping on the undersuit is now an olive green color, the same as the undersuit's main color.
The original Mark VI helmet, chest, shoulder, arm, and leg armor are available in the Infinity mode after completion of Halo 4's campaign on Legendary difficulty. Though the helmet is mostly unchanged from its Halo 3 incarnation, the rest of the suit has received several minor aesthetic updates. Canonically, this version of the Mark VI is available for issue to Spartan-IVs, having been updated for use with GEN2.
The GEN1 and GEN2 Mark VI are also available in Halo 5: Guardians multiplayer. The GEN1 Mark VI is identical to the Halo 4 version apart from the restoration of the armor protecting the groin.
