CENTURION-class Mjolnir

The MJOLNIR Powered Assault Armor/Centurion is a variant of the MJOLNIR Mark VI armor. Its primary purpose is to serve as a testbed for new technologies before they are incorporated into the MJOLNIR (GEN2) platform, a more modern armor utilized by Spartan-IVs.

Operational history
Spartan Fred-104 received his Centurion armor upon upgrading to the Mark VI platform at his return to Earth in October 2552, shortly before the Battle of Earth. With it, he 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.
