ROGUE-class Mjolnir

The Mark VI(A) MJOLNIR Powered Assault Armor, otherwise known as the 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.

Characteristics
Unlock: Unlock the Spartan Officer achievement, only obtainable through online multiplayer.

The helmet has one small visor that resembles a pair of sunglasses, rather than the typical MJOLNIR 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".

Trivia

 * The Rogue and Hayabusa armors are the only Halo 3 Armor Permutations that did not return in Halo: Reach although the EOD helmet with the UA/HUL attachment does bear a resemblance to the Rogue helmet.
