EOD-class Mjolnir

The Mark VI MJOLNIR Powered Assault Armor/EOD variant, more commonly known as Explosive Ordnance Disposal Armor, and abbreviated as EOD Armor, 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 armor. It is an armor permutation in Halo 3 multiplayer. Bungie has confirmed that no armor 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 armor, 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 eye pieces. They are more akin to a pair of goggles than the typically wide visor plates of other MJOLNIR armor variants. 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 re-breathers.

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

Chest Characteristics
The chestplate looks to be a bulkier version of the Mark VI armor variant. This design was most likely intended to increase wearer survivability in the event of a full-frontal explosion. The EOD chestplate also bears a striking resemblance to the design of the MJOLNIR Mark V armor's chestplate. (Halo:Combat Evolved armor.) Because of this, many players use it in conjunction with the Mark V helmet and Mark VI shoulders to create an accurate replica of the original Mark 5 armor.
