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.

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 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 designed specifically to protect Spartans during operations involving the handling of explosive ordnance [e.g., clearing/planting land mines, demolishing enemy structures/material].

Helmet Characteristics
The Helmet is mostly squared off with two separate eye pieces like a pair of goggles rather than the typical wide visors of the MJOLNIR armors. It 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 re-breathers.

Shoulder Characteristics
The shoulder plates of the EOD armor bear a great resemblance to those of Space Marines from Warhammer 40,000, though they are much smaller along the covering of of the shoulder and the upper arm. EOD plates are more squared off, lack the trim, and have a small energy shield generator set into them. These generators are an integral part of the standard MJOLNIR energy shield system, and can be found in different shapes and sizes on all MJOLNIR armor variants.

Chest Characteristics
The EOD chest looks to be like a bulkier version of the Mark VI armor variant. This is most likely to increase survivability of frontal explosions or attacks. Interestingly, the chest piece also strikes a resemblance to the Mark V chest. (Halo:Combat Evolved armor.)

Trivia

 * If you get Mark IV shoulders, EOD body and Mark V helmet and put them together they make a close replica of the real Mark V armour.
 * The helmet of the EOD armor has been reputed to be similar to, among other things, the Helghast armor from Killzone (A game for the PS2) and the helmets worn by TCTF troopers in the Bungie game "Oni".
 * The armor's chest plate bears a striking resemblance to the chest plate of the MJOLNIR Mark V Powered Assault Armor.
