This article is about the MJOLNIR Mark V[G] variant developed from Project GUNGNIR. For the MJOLNIR Mark IV[G] variant, also known as the Grenadier armor, see GRENADIER-class Mjolnir.
GUNGNIR-class Mjolnir, also designated as the MJOLNIR Powered Assault Armor/G variant on the Mark V platform, is a MJOLNIR armor variant originally designed by Misriah Armory, with the GEN2 version being manufactured by Hannibal Weapon Systems.
The GUNGNIR helmet's visor is a "blast visor", which is boxy and comes with more facial protection than any other helmet as it fully covers the front of the head and it replaces the usage of a visor with a small camera on the left that displays the outside to the user. It bears a white stripe running down the right side with the Norse symbol for Gungnir in the center. The helmet also has Wyrd III synchronized optimization which seamlessly connects the helmet to an M6 Spartan Laser to allow full access to the weapon. Project GUNGNIR also developed supplementary armor systems, including shoulder pauldrons and knee guards.
It was developed as a part of the GUNGNIR Program by a separate but parallel team, as a modification of existing Mjolnir variants optimized for the use of the M6 Spartan Laser. The GUNGNIR program also produced several supplemental armor like pauldrons and knee guards.
The shoulder pauldrons and knee guards were employed on the cross-branch Battle Dress Uniform, which was adapted into the UNSC Army BDU, the UNSC Marine Corps BDU, and a variant of the ODST armor.
The physical architecture of the GEN2 GUNGNIR body armor strongly resembles the COS-class Mjolnir, which was tested on ANVIL Station. The GEN2 GUNGNIR helmet, unlike its Mark V iteration, is round. Like the previous iterations, there is no visor, but the video camera has moved from the left side to the right side of the helmet. The helmet is less angular overall, and the front extends much less than its predecessor.
The helmet continues to have Wyrd III integrated video optics, though the helmet has enhanced cranial plating now. The chest has a centralized power-distribution capacitor(Servo L-903), and a breach-anchored collar system for in-field modification.
Despite being considered an exclusive armor set, many Spartans have adopted GUNGNIR regardless of their weapon loadouts due to its isolated video optics, Wyrd III sensory optimization, and enhanced cranial plating. This was especially useful when operating at or near Covenant manufacturing sites, as it protected against intense flare radiometric conditions.
The GUNGNIR target acquisition and tracking system has been adapted into various UNSC weapon systems.
Halo: Reach - GEN1 Mark V
All GUNGNIR armor types can be unlocked in the Halo: Reach's Armory through the game's purchase system via the use of cR. In Halo: The Master Chief Collection, the GUNGNIR set is attainable in the Season 1: Noble progression system.
Halo 4 - GEN2
GUNGNIR was one of the armor permutations to return, albeit completely redesigned for GEN2, in Halo 4. In The Master Chief Collection, the GUNGNIR set and its Pulse (PULS) skin variant are available by default.
Halo 5: Guardians - GEN2
The Halo 4 design of GUNGNIR returns in Halo 5: Guardians. The helmet and body armor are unlockable as armor permutations through the Requisition system. The body armor includes the GUNGNIR chest and shoulders, an unknown set of forearms, and LG-50 Bulk legs. The GEN2 GUNGNIR set only has one alternate skin, Dvalin.
Halo Infinite - Upgraded GEN1 and GEN3
The GUNGNIR Mark V shoulder pauldrons return in Halo Infinite, available under the SAP category for the Mark V(B) core. The Mark V knee guards will also be available. The GEN3 GUNGNIR helmet is available for use on the Mark VII core.
