EVA-class Mjolnir

The MJOLNIR Powered Assault Armor/V variant is a type of United Nations Space Command body armor.

It is more commonly known as Extra Vehicular Activity Armor, and abbreviated as EVA Armor.

Introduction
The EVA Armor is a variant of the standard Mark VI MJOLNIR powered battle armor, specialized to increase exoatmospheric endurance and improving mobility in zero gravity for the SPARTAN-II supersoldiers without thrusters and successor to the Mk. IV V variant. 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 variant was developed and tested at UNSC Low/Zero Gravity Testing Facility facility in Lister, Aigburth on Ganymede, integrating feedback gathered from the Summa Deep Space Incident. The Mjolnir/V variant focuses on increasing exoatmospheric endurance and improving mobility in zero gravity without the use of thrusters.

Its predecessor, the Mark IV MJOLNIR Powered Assault Armor/V variant was in front line use as early as 2531. It could be attatched to a T-PACK like the standard MJOLNIR armor and used for deep space ops. SPARTAN-051 went missing when Blue Team was on one such op, in Mark IV Variant V MJOLNIR armor.

Helmet Characteristics
The EVA armor's helmet is aesthetically similar to SPI armor's helmet. However, the rim from the jaw down to the chin is thinner, and around the back of the head it has a quarter sphere shape. Also, the helmet is much more rounded than the SPI helmet. The helmet may have a large, all around visor for maximum amount of vision during EVA operations. The helmet should provide better peripheral vision for the wearer than any other spartan armor variant, yet this gives no advantage to the player because the screen doesn't surround the player's head.

Shoulder Characteristics
The shoulder pads are larger than the standard MJOLNIR pads and feature a long attachment to their center which is similar to a part of the SPI shoulder pad.They also seem to be somewhat cubical.

Chest Characteristics
The chest plate appears to be MJOLNIR chest plate but with two pieces added on and the straps between the back plate and front plate have a buckle like object on them. The objects of the chest plate may be pieces of equipment for EVA operations. Also, the top rim protrudes out a bit more then the MJOLNIR
