EOD-class Mjolnir (Explosive Ordnance Disposal), also designated as the MJOLNIR Powered Assault Armor/EOD variant,[3] is a MJOLNIR armor variant originally designed by Materials Group,[1] with the GEN2 version being manufactured by the Naphtali Contractor Corporation.[4]
GEN1 overview
Design details
The helmet was designed to channel the pressure wave of a nearby detonation around the user's head, significantly reducing the likelihood of decapitation in the event of an explosion.[3] 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 that involve the handling of explosive ordnance (e.g., clearing/planting land mines, demolishing enemy structures/material and, or planting/defusing bombs).[5][6] The helmet can be fitted with the AN/PZY-6011Y TYPHON and AN/PCK-221 FARNDALE Command Network Modules, the Type E3 UA module and a CBRN module.
Development history
The MJOLNIR/EOD variant was originally created at the UNSC Damascus Materials Testing Facility on Chi Ceti 4. The EOD variant is speculated to have been developed in response to the death of Samuel-034 (the first Spartan killed in action) in November 2525[7] and entered service in 2531.[8] As late as 2558 the GEN1 Mark V version of the EOD helmet could be requisitioned by Spartan Operations personnel for use with their GEN2 Mjolnir suits.[9] With the advent of the GEN3 Mjolnir in 2559, both the GEN1 Mark IV and Mark V EOD helmets were upgraded to be compatible with it.[10]

Usage
EOD is fielded by Spartans deep in enemy lines, allowing them to navigate dangerous territory to disable or destroy enemy mines before the UNSC properly arrived.[1] In the post-war era, the GEN1 EOD set, specifically the helmet, is still favored by Spartan combat divers and pioneers tasked with demolition roles.[9]
GEN2 overview
Design details
The helmet has a pressure-resistant hardened rebreather unit. The reactor has alternating heat-tempered balance drives. The pauldrons are flow-distributing ceramic plates.[2] The GEN2 kit also includes anterior torque couplings.[11]
Development history
In 2554, Abilene's Naphtali Contractor Corporation took control over the EOD armor's production,[4] and adjusted the systems plate configuration to reduce the potential for dismemberment during explosive ordnance activity and facilitation.[12] It was tested at the Buffalo Breaker Yards. They proposed numerous enhancements to the armor's systematic approach to the GEN2 framework.[2]
In-game information
Halo 3 - Mark VI GEN1
The EOD armor permutation is unlockable in Halo 3. In the Halo: The Master Chief Collection edition of Halo 3, the EOD armor (like all Halo 3 permutations) is unlocked by default.
The Bungie Armor is a slight variation of the EOD chestpiece. Bungie Armor lacks the three mid-level lights and has an effect that causes flames to appear around the helmet.

Trivia
- During the Halo: Reach Multiplayer Beta, the final model for the GUNGNIR shoulder pauldron was designated as the EOD shoulder pauldrons, and costed 1,000 cR.[14]
- The Caduceus emblem that appears on the Mark V EOD helmet also appears on med packs, Army medics, and the Tactical/Trauma Kit armor permutation. This suggests that the EOD may also have an intended secondary role to provide medical assistance to wounded allies in dangerous situations. It's possible that there may be a non-MJOLNIR variant of the helmet for use by UNSC medical personnel, likely in toxic environments where the distinctive CBRN would aid in operations.
