SECURITY-class Mjolnir



The Mark V(m) MJOLNIR Powered Assault Armor, otherwise known as the Security Armor, is a type of United Nations Space Command body armor.

Introduction
The Security Armor is a variant of the standard Mark V MJOLNIR powered battle armor. It is an armor permutation in Halo 3 multiplayer. The armor looks like it would provide more protection to the user, but Bungie has confirmed all of the armor permutations have no effect on gameplay. This armor permutation is based off of the main character in the Marathon series.

Development and History
The MJOLNIR V(m) variant was manufactured in the Misriah Armory Facility on Mars in 2528, 14 years before the Mark V entered production. Like the Mark V, it has been upgraded to be compatible with all current generation MJOLNIR variants.

Helmet Characteristics
The helmet’s most noticeable feature is the large figure-eight shaped; bug-eyed style visor, inspired by the protagonist of Halo's precursor, Marathon. Other than that the helmet is largely bland, with a small raised section on the forehead in the form of a Marathon logo. The helmet could be derived from the helmets of modern-day police riot control gear. Wearing the helmet will also add a small antenna on the back of the armor.

Shoulder Characteristics
The Shoulder pads are quite large, with a distinct rounded section and upper center then a trapezium shaped arm guard going out the bottom and a rounded armor section above that.

Chest Characteristics
The Security Armor does not have a known chest plate, although wearing the helmet will give the player a distinct "antenna" on the right side of the back plate. It could be thought that the Katana chest plate was intended to go with the armor, as they unlock at the same time. Or it could just be an unrelated, extra present from Bungie.

Unlock

 * Shoulders: The shoulders unlock after getting the achievement Marathon Man.

Trivia

 * There is a Marathon symbol above the visor on the helmet.
 * If a player chooses to use the Helmet, a dual antenna is placed on the right side of the body. This may be a reference to the antenna Master Chief had pre-Halo: Combat Evolved at the Mac World Trailer. Also, as the Security is the earlier version of the Mark V, it may help indicate this.
 * The shoulder pads seem similar to the right-arm shoulder pad for the MJOLNIR Mark IV armor.
