Improve tactical awareness


COMMANDO-class Mjolnir, also designated as the MJOLNIR Powered Assault Armor/K variant, is a MJOLNIR armor variant originally designed by Chalybs Defense Solutions and Special Warfare Center,[1] with the GEN2 version being manufactured by the Naphtali Contractor Corporation.[2]

GEN1 overview[edit]


The K variant's helmet is designed to improve a Spartan's tactical awareness without the use of the modular packages that can be added to the MJOLNIR platform. The Commando helmet package includes the most comprehensive, up-to-date tactical hardware and software systems.[1] The variant's shoulder pauldrons offer excellent protection at the cost of limited joint mobility. The field support attachment provides additional functionality to the MJOLNIR armor.[1] It was designed for special operations.[3]

Development history[edit]

The K variant was developed at the Special Warfare Center in Seongnam, United Korea, to aid Spartan supersoldiers in specialized assaults on conventional military targets. When production for the K variant was approved, Chalybs Defense Solutions was awarded the contract to manufacture the armor, with final testing conducted at the Chalybs Testing Preserve.[1]

The Mark IV version, which was simply a modification to the MJOLNIR suit rather than a distinct variant,[1][note 1] originated as a prototype for standardized team leader kits.[4] The Mark V[B] version was introduced near the end of the war in November 2551 due to the success of the Mark IV ad hoc. Unlike the previous iteration, the Mark V version was designed as a fully featured variant of the Mark V system.[1] It was first deployed during the siege of the Inner Colonies relatively late in the Human-Covenant War.[1]


Several Spartans and team leaders made use of this system. Carter-A259 led Noble Team through several operations wearing the armor during the Human-Covenant War.[3]

GEN2 overview[edit]

Now produced by the NCC, this armor is loosely based on the GEN1 variant.


Naphtali Contractor Corporation's version includes a helmet, torso armor, and shoulder pauldrons. The GEN2 variant is loosely based on its GEN1 predecessor.[6]

The helmet has a built in CNM suite for tactical application; this enables real-time synchronization with the UNSC battlenet.[7] The helmet also has field elaboration software for real-time combat intelligence modification. The body has a wide-range fireteam allocation module.[2]

Though the GEN2 COMMANDO-class suite only vaguely resembles its Mark V predecessor, the GEN2 NOBLE-class Mjolnir is a recreation of the Mark V/K's external architecture.[8]

Development history[edit]

After Meridian fell, all contracts that Chalybs had were absorbed into companies that survived the war. NCC was the company that got a hold of Commando and started to circumvent its GEN1 limitations, making the armor more open for more users, and beginning production of the GEN2 of the Commando armor.[2] This acquisition of Chalybs' original COMMANDO designs also allowed NCC to bring their GEN2 Mjolnir armor to market several months ahead of schedule.[7]

Testing for the armor began at the Buffalo Breaker Yards.[2]


While the armor was made more open for more users, many team leaders still opt to use Commando systems possibly out of tradition.[2]

List of appearances[edit]


  1. ^ In Birth of a Spartan Carter-A259's Mark IV/K prototype is identical to the Mark V version that he used later in the war, despite The Essential Visual Guide stating that the Mark IV/K was an ad hoc modification of the contemporary Mark IV suit. Frank O'Connor has stated that this suit was a prototype that was still being researched and did not see deployment for some time.
