CENTURION-class Mjolnir

The MJOLNIR Powered Assault Armor/Centurion is a variant of the MJOLNIR Powered Assault Armor. It features C412SR technology which, combined with the warfighting skills of the Spartan wearer, has had major ramifications on UNSC doctrine on battlespace shaping and operations planning. The suit's threat management system also features the latest situational awareness tactical software and cognition-enhancing neural interlinks.

Operational history
The Centurion armor was manufactured by ONI's Watershed Division. Spartan Fred-104 received a prototype Centurion armor upon upgrading to the Mark VI platform at his return to Earth in October 2552, shortly before the Battle of Earth. The primary purpose of Fred's suit was to serve as a testbed for new technologies before they were incorporated into the MJOLNIR (GEN2) platform, a more modern armor that would later be utilized by Spartan-IVs. With it, Frederic fought numerous battles on Earth, and later participated in the Battle of Onyx. Following his return to Earth in 2553, he continued to field-test multiple variants of the Centurion armor during highly confidential operations, until at least 2557. By 2558, the Centurion armor was adapted to MJOLNIR [GEN2] systems.
