EOD-class Mjolnir

The Mark VI MJOLNIR Powered Assault Armour/EOD variant, more commonly known as Explosive Ordnance Disposal Armour, and abbreviated as EOD Armour, is a type of United Nations Space Command body armor. It is first seen in Halo 3.

Introduction
The EOD (Explosive Ordinance Disposal) is a variant of the standard Mark VI MJOLNIR powered battle armour. It is an armor permutation in Halo 3 multiplayer. Bungie has confirmed that no armour permutation has an effect on gameplay.

Development and History
The MJOLNIR/EOD variant was created at UNSC Damascus Materials Testing Facility facility on Chi Ceti 4. The helmet was designed to channel the pressure wave of an accidental detonation around the user's head, significantly reducing the likelihood of decapitation in the event of an explosion. The MJOLNIR/EOD variant's pauldrons and chest plate were designed specifically to reduce the number of grabbing edges on the armour, decreasing the likelihood of dismemberment, and protecting Spartans during operations involving the handling of explosive ordnance [e.g., clearing/planting land mines, demolishing enemy structures/material and, or planting/defusing bombs].

Helmet Characteristics
The helmet is mostly squared off with two separate eyepieces, rather than a bulky visor. They are more akin to a pair of goggles excluding the other MJOLNIR armour variants that are visor-adorned. In actual combat, this would highly increase protection to the face, but reduce the field of vision considerably. The helmet also has a single plate over the nose and mouth and a pair of rectangular objects along each cheek, assumed to be cheek guards and/or lengthy re-breathers.

Shoulder Characteristics
The shoulders are large and rounded. They have been optimised for EOD missions and are designed to decrease the chances of dismemberment if the wearer were caught in a blast.

Chest Characteristics
The chest plate looks to be a bulkier version of the Mark VI armour variant. This design was most likely intended to increase wearer survivability in the event of a full-frontal explosion by decreasing the probability of shrapnel harming anything vital. The EOD chest plate also bears a striking resemblance to the design of the MJOLNIR Mark V armour’s chest plate. (From Halo: Combat Evolved.) Because of this, many players use it in conjunction with the Mark V helmet and Mark VI shoulders to create an accurate replica of Mark V armour.
