ROGUE-class Mjolnir

The Mark VI(A) MJOLNIR Powered Assault Armor, otherwise known as the Rogue Helmet or just Rogue, is a privately manufactured variant of the MJOLNIR Mark VI armor.

Development and History
The Mark VI(A) armor was the first of many "privatized" variants, manufactured by private industrial firms. With the fall of the Outer Colonies, the UNSC called upon private industries to manufacture classified war material.

Helmet Characteristics
Unlock: Unlock the Spartan Officer achievement, obtainable only through online multiplayer. The helmet has one small visor that resembles a pair of sunglasses, rather than the normal and typical MJOLNIR Mark VI visor. The mouth-guard appears longer and thicker with an added "hole" in the center of the mouthpiece, it seems that it is actually part of the helmet rather then an add-on otherwise it wouldn't be classified as a separate variant. The top of the helmet, which has been mistaken for the "stealth" helmet, is much more rounded as well. The mouth guard rounds, shapes, and cups into a circular black piece in front of the mouth that forms the aforementioned "hole".

Shoulder Characteristics
This armor permutation has no shoulder armor.

Chest Characteristics
This armor permutation has no chest plating.

Trivia
