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 around the user's head, significantly reducing the likelihood of decapitation in the event of an explosion. The Mjolnir/EOD variants 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 and or planting/defusing bombs].

Helmet Characteristics
The Helmet is mostly squared off with two separate eye pieces if any comparable and akin to a pair of goggles rather than the typical wide visor of the MJOLNIR armor variants. 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 EOD shoulders are large and rounded. They have been optimized for EOD missions and were designed to reduce the likelihood of dismemberment upon the wearer.

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 VI shoulders, EOD body and Mark V helmet and put them together they make an extremely close replica of the actual 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", Stormtrooper helmets from Star Wars, Darth Vader from Star Wars, or the CoG soldiers with helms from Gears of War.
 * The EOD shoulder pads appear similar to the shoulder pads of the Space Marines in Warhammer 40,000, though much smaller.
 * This armor is recognized as an achievement due to the fact that you must beat the campaign on Legendary to unlock the complete set.
