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. Bungie has confirmed all of the armor permutations have no effect on gameplay.

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 like 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. 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

 * Head: Get all 1000 Gamerscore from Halo 3.
 * Shoulders: Get 750 Gamerscore from Halo 3.
 * Body: N/A

Note: the requirements to unlock the shoulders seem random. 750+ gamerscore from Halo 3 is the established guideline, but some players have unlocked the armor far earlier or far later than that score, and some not at all.(ex. 560+ or 890+) The armor is also prone to re-locking itself after a limited time. By completing two campaign metagame achievements, it can unlock the shoulders, but it is unconfirmed if you need a set amount of gamerscore first.

Trivia

 * The Armor is very similar to that of the protagonist’s armor in Marathon
 * 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 may also help indicate this.
 * This armor is most likely named after the protagonist in Marathon as he is usually refered to as the Security Officer by fans.
 * The shoulder pads seem similair to the right-arm shoulder pad for the MJOLNIR Mark IV Armor.
