Mjolnir/UA, short for up-armor, refers a variety of supplemental armor attachments and accessories compatible with the Mjolnir Powered Assault Armor. Like some other Mjolnir variants, many of the UA pieces are not exclusive to the Mjolnir system, but are in use by regular UNSC Army or Marine troops as well. Many UA attachments are available as Armor Permutations in Halo: Reach.[1]


The various helmets available have up-armored variants, often coupled with an external helmet addition such as a HUL. The UA helmet attachments often consist of metal plates or bracers fixed near the user's forehead to give better protection in combat.




Price: 600 cR Supplemental armor for the default Mark V chest, including additional pouches for increased storage capacity.
