MATERIALS GROUP
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 exoskeletons which preceded it, as well as several specialized variant models.

On February 10, 2559, four months after the rise of Cortana and the Created, the Materials Group manufactured the [GEN3] armor

In the vastness that is Halo and the armor combinations, variants created and perfected across the generations we see fit that ONI's uniform be consistent to the true purpose of a clan. That is for us to be fun, unified and playing Halo for all of the features included, the utilization of all of its customization regardless of discipline.

In addition to the armors created by the Materials Group, the ONI Watershed Division and the ONI Beta-5 Division all have options available with the only limitation of the armors reserved to the prestige of the Spartan Programs and Orbital Drop Shock Division. These armor sets are distinguished, we all know them to be true to its purpose whatever variant they may be and ask all members to abide in respecting the SPARTAN-II, SPARTAN-III, SPARTAN-IV and ODSTs in not equipping the armor sets unless you earn the status here.
