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.Due to the fact that a lot of gamers online have beaten campaign on legendary, the EOD armor should be seen more often, though some players dislike the looks of it.

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 and or planting/defusing bombs].

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 EOD shoulders are large and rounded. They have been optimized for EOD missions and were designed to reduce the likelyhood 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.)
