Technical specifications



ODST MJOLNIR armor is a MJOLNIR Powered Assault Armor variant based on the venerable ODST armor, updated for compatibility with various powered armor systems.

GEN1 overview[edit]


On the GEN1 platform, ODST usage with MJOLNIR largely consists of standard shoulder pauldrons and chest plate on top of the default MJOLNIR Mark V (B) MJOLNIR.[2] The ODST helmet, however, is compatible with both the Mark V[2] and Mark VI systems, seeing the use of many technologies initially developed for the MJOLNIR program.[3]

The ODST helmet on the Mark V (B) platform can support an Command Network Module, Hardened Uplink, CBRN module or UA module.[2]

GEN2 overview[edit]


For MJOLNIR Powered Assault Armor (GEN2), the ODST armor was given extensive treatment by Cascade Stronghold Technologies at their test site at Mindoro, Lhopat, Cascade.[1] Almost inevitably due to the high numbers of former-ODST personnel within the Spartan Operations branch, the first-generation MJOLNIR/ODST variant was updated for compatibility with MJOLNIR (GEN2). Despite considerable differences from the standard version of the armor, the system contains many features expected of Special Forces gear, making it desirable for use by former ODSTs.[6]

The GEN2/ODST variant shares several design elements with its predecessor, though it also sports several changes. It still uses the standard helmet and shoulder pauldrons; it also features upgraded versions of the Mark 117 chestplate and the M/LBE Hard Case. However, the chestplate covers more of the torso below the thoracic cavity. The rest of the armor, including the greaves and cuisses, gauntlets, and boots, is more closely derived from the regular MJOLNIR (GEN2) milieu.[4]


A number of similar armor systems based on the ODST set exist on the GEN2 platform;

In-game information[edit]

Halo 3[edit]

The ODST helmet is available as an armor permutation in Halo 3 multiplayer. The Spartan version of the helmet differs from the standard version in the polarization color of its visor; regular ODST helmets have bluish-silver polarization, while the MJOLNIR ODST helmet retains the gold electroplating possessed by most MJOLNIR armor.[3] In The Master Chief Collection, the ODST helmet (like all helmets) can use any of the visor colours introduced in Season 3.

Halo: Reach[edit]

"The ODST helmet is one of the most recognizable faces of the UNSC's Special Forces."

In Halo: Reach, two upgrades are available for the helmet. The first, (UA/CNM), adds an up-armor plate with a Command Network Module on the left side, and the second, (CBRN/HUL), adds a Chemical, Biological, Radiological, and Nuclear Module with a Hardened Uplink Module on the right side. The shoulder pauldrons, breastplate, and helmet of the ODST armor are also available for purchase in the Armory. Unlike in Halo 3, the ODST armor can be used in all game modes.
