ATHLON-class Mjolnir

MJOLNIR Powered Assault Armor/Athlon is a variant of the GEN2 MJOLNIR powered armor used during combat training exercises and developed by Misriah Armory. It is much sleeker than most MJOLNIR variants, reminiscent of the series' Contoured-pattern gauntlets and greaves. Two teams of SPARTAN-IVs (red and blue) wore such suits while training on a dedicated space station at some point after February 2558.

Production note
First shown in the Halo 5: Guardians Multiplayer Beta announcement trailer, the armor set is part of a particular game mode in Halo 5: Guardians.
