==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.{{Ref/Reuse|h3helmet}} 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 [[Spartan]]s during operations that involve the handling of explosive ordnance (e.g., clearing/planting land mines, demolishing enemy structures/material and, or planting/defusing bombs).{{Ref/Game|Id=h3shoulder|Game=H3|What=Armor permutations (Halo 3)|WhatText=Spartan Armor Customization|Detail=EOD - Shoulder Description|Quote=Developed at the UNSC Damascus Materials Testing Facility on Chi Ceti 4, the Mjolnir/EOD variant was designed specifically to reduce the number of grabbing edges on the armor, decreasing the likelihood of dismemberment.}}{{Ref/Game|Id=h3chest|Game=H3|What=Armor permutations (Halo 3)|WhatText=Spartan Armor Customization|Detail=EOD - Chest Description|Quote=This variant was designed specifically to protect Spartans during operations involving the handling of explosive ordnance (e.g., cleaning/planting land mines, demolishing enemy structures/materiel).}} The helmet can be fitted with the [[AN/PZY-6011Y TYPHON]] and [[AN/PCK-221 FARNDALE]] Command Network Modules, the [[UA/Type E3|Type E3]] UA module and a [[CBRN module#EOD-style module|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{{Ref/Site|Id=Waypoint|D=14|M=03|Y=2011|URL=http://halo.xbox.com/en-us/intel/theuniverse/tech/video/the-mjolnir-project-2/46e89c1a-f619-41e2-ad7f-ab65c61ca2df|Site=Halo Waypoint|Page=MJOLNIR 2|LocalArchive=The MJOLNIR Project}} and entered service in [[2531]].{{Ref/Game|Id=HR|HR|Armor customization (Halo: Reach)|The Armory|Detail=EOD - Helmet Description|Quote=Developed at the Damascus Materials Testing Facility on X Ceti 4; entered service in 2531.

===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.{{Ref/Reuse|EVG}} 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.{{Ref/Reuse|H5G}}

==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.{{Ref/Reuse|H4EVG}} The GEN2 kit also includes anterior torque couplings.{{Ref/Game|Id=H4LE|[[Halo 4 Limited Edition]]|Detail=[[Infinity Briefing Packet|''Infinity'' briefing packet]]}}

===Development history===
In [[2554]], Abilene's [[Naphtali Contractor Corporation]] took control over the EOD armor's production,{{Ref/Reuse|H4}} and adjusted the systems plate configuration to reduce the potential for dismemberment during explosive ordnance activity and facilitation.{{Ref/Site|Id=h4guide|URL=http://www.halowaypoint.com/en-us/intel/inteldetail/9c6e4d8c-4060-4751-9f5d-a317fe7ec2c5/eod-|Site=Halo Waypoint|Page=Halo 4 Interactive Guide - Armor Types: EOD|D=23|M=4|Y=2013|LocalArchive=Halo 4 Interactive Guide#Armor Types}} It was tested at the [[Buffalo Breaker Yards]]. They proposed numerous enhancements to the armor's systematic approach to the GEN2 framework.{{Ref/Reuse|H4EVG}}

==In-game information==
===''Halo 3'' - Mark VI GEN1===
The EOD [[Armor customization (Halo 3)|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.

===''Halo: Reach'' - Mark V GEN1===
The EOD helmet returns in ''[[Halo: Reach]]'', though it features some minor different aesthetics than the Mark VI EOD helmet seen in ''Halo 3''. All EOD helmet variants can be unlocked in the ''[[Halo: Reach]]''{{'}}s [[Armor customization (Halo: Reach)|Armory]] through the game's purchase system via the use of [[Credits|cR]]. In ''Halo: The Master Chief Collection'', the EOD helmet variants are attainable in the [[Season 1: Noble]] progression system. 

The default EOD helmet features the [[CBRN module]], which is also available for the [[SECURITY-class Mjolnir|Security]] and [[GUNGNIR-class Mjolnir|GUNGNIR]] helmets.

==Trivia==
*During the [[Halo: Reach Multiplayer Beta|''Halo: Reach'' Multiplayer Beta]], the final model for the [[GUNGNIR-class Mjolnir|GUNGNIR]] shoulder pauldron was designated as the EOD shoulder pauldrons, and costed 1,000 [[Credits|cR]].{{Ref/YouTube|rRYRscwNMCY|haloinfectedX|Halo: Reach beta Armor (customizations)}}
*The Caduceus emblem that appears on the Mark V EOD helmet also appears on med packs, Army medics, and the [[MJOLNIR Powered Assault Armor/Tactical#Tactical/Trauma Kit|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.
