{{Era|UNSC|HCW|Post}}

'''Materials Group''' is a division of the [[Office of Naval Intelligence]] that is responsible for researching, developing, and manufacturing technologically advanced matériel. The Materials Group's most important development has been the design of the [[MJOLNIR Powered Assault Armor]] and the [[powered exoskeleton]]s which preceded it,<ref name="EVG 118">'''[[Halo: The Essential Visual Guide]]''', ''page 118''</ref><ref name="EVG 119">'''Halo: The Essential Visual Guide''', ''page 119''</ref><ref name="EVG 120">'''Halo: The Essential Visual Guide''', ''page 120''</ref>  as well as several specialized variant models.<ref name="EVG 65">'''Halo: The Essential Visual Guide''', ''page 65''</ref><ref name="EVG 66">'''Halo: The Essential Visual Guide''', ''page 66''</ref><ref name="EVG 85">'''Halo: The Essential Visual Guide''', ''page 85''</ref><ref name="EVG 92">'''Halo: The Essential Visual Guide''', ''page 92''</ref><ref name="EVG 152">'''Halo: The Essential Visual Guide''', ''page 152''</ref><ref name="EVG 165">'''Halo: The Essential Visual Guide''', ''page 165''</ref>

**[[GRENADIER-class Mjolnir|Grenadier]] variant - Developed from early prototypes of the original MJOLNIR (later Mark IV) helmet. Provides superior armor and improved heads-up display to improve performance of grenadiers.{{Ref/Reuse|EVG 85}}

**[[EOD-class Mjolnir|EOD]] variant - Designed to increase survivability when in close proximity to an explosion. Developed and manufactured at the Damascus Materials Testing Facility, the development site of the original MJOLNIR.{{Ref/Reuse|EVG 65}}

**[[EVA-class Mjolnir|EVA]] variant - One of the earliest MJOLNIR variants. Designed to aid Spartans' mobility, field of view, and endurance during [[extra-vehicular activity]]. Developed and manufactured at Materials Group's [[Low/Zero Gravity Testing Facility]] in [[Lister]], [[Aigburth]], [[Ganymede]].{{Ref/Reuse|EVG 66}}

**[[HAZOP-class Mjolnir|HAZOP]] variant - Introduced as a variant of the Mark V system. Designed to improve survivability in extremely hazardous environments. Prototypes were fielded in the years prior to launch.{{Ref/Reuse|EVG 92}}

**[[RECON-class Mjolnir|Recon]] variant - Designed to improve stealth by reducing infrared signature and [[Čerenkov radiation]] emissions. Developed at the [[Beta-5 Division]]'s [[Beta-5 Division Ordnance Testing Facility|Ordnance Testing Facility]] in [[Swanbourne]], [[wikipedia:Western Australia|Western Australia]], parallel to the S variant.{{Ref/Reuse|EVG 152}} After the Human-Covenant War, the [[Imbrium Machine Complex]] took ownership of Recon production.

**[[SCOUT-class Mjolnir|Scout]] variant - Designed to improved stealth by reducing infrared signature and Čerenkov radiation emissions. Developed at B5D Ordnance Testing Facility in Swanbourne, Western Australia, parallel to the Mark VI/R variant.

*[[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR Powered Assault Armor [GEN2]]] - The second generation of MJOLNIR armor, replacing GEN1 (Mark IV-VII)

**[[DECIMATOR-class Mjolnir|Decimator]] variant

**EVA variant

**[[PROTECTOR-class Mjolnir|Protector]] variant

**[[SCANNER-class Mjolnir|Scanner]] variant

**Scout variant

**[[SOLDIER-class Mjolnir|Soldier]] variant

**[[WARRIOR-class Mjolnir|Warrior]] variant

*[[MJOLNIR Powered Assault Armor (GEN3)]] - The third generation of MJOLNIR armor, replacing the former two MJOLNIR generations.

**[[Mark V Zeta]] variant - Spartans assigned to ONI's [[Xeno-Materials Exploitation Group]] on [[Installation 07]] found that their upgraded Mark V's mix of high-threat response and surveillance interlinks were ideal for the ring's peculiar operating environment.{{Ref/Site|Id=CFParallel|URL=https://www.halowaypoint.com/en-us/news/parallel-threads|Site=Halo Waypoint|Page=Canon Fodder - Parallel Threads|D=25|M=6|Y=2021}}

**[[MJOLNIR Powered Assault Armor/Mark VII|Mark VII]] variant - Though the GEN3 model of Mark VII MJOLNIR does represent a generational leap for the MJOLNIR platform for actively deployed Spartans, some elements tested with the GEN1 and GEN2 Mark VII remain in the prototype stage due to unreliability or cost factors, such as integration of [[Forerunner]]-derived [[Nanotechnology|nanomachine]] elements and full [[Energy shielding|shield]]-shaping.{{Ref/Site|Id=CFDistance|URL=https://www.halowaypoint.com/en-us/news/despite-distance|Site=Halo Waypoint|Page=Canon Fodder - Despite Distance|D=27|M=6|Y=2021}}

**[[SOLDIER-class Mjolnir|Soldier]] variant - The latest iteration of the Soldier helmet features a new revision of Materials Group's combat catalyst firmware. The fireteam synchronization features remain unfinished circa [[2560]], but [[Catherine Halsey|Dr. Halsey]]'s interest may accelerate development.{{Ref/Site|Id=CFShowcase|URL=https://www.halowaypoint.com/en-us/news/showcase-sensitive|Site=Halo Waypoint|Page=Canon Fodder - Showcase Sensitive|D=27|M=6|Y=2021}}
