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, with the GEN2 version being manufactured by the Naphtali Contractor Corporation.
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. 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. It was designed for special operations.
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.
The Mark IV version, which was simply a modification to the MJOLNIR suit rather than a distinct variant,[note 1] originated as a prototype for standardized team leader kits. 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. It was first deployed during the siege of the Inner Colonies relatively late in the Human-Covenant War.
The helmet has a built in CNM suite for tactical application; this enables real-time synchronization with the UNSC battlenet. The helmet also has field elaboration software for real-time combat intelligence modification. The body has a wide-range fireteam allocation module.
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. This acquisition of Chalybs' original COMMANDO designs also allowed NCC to bring their GEN2 Mjolnir armor to market several months ahead of schedule.
While the armor was made more open for more users, many team leaders still opt to use Commando systems possibly out of tradition.

The Commando helmet can be viewed at the rank of Lieutenant Colonel and can be unlocked once at the rank of Commander. The helmet resembles the HAZOP helmet with a small area of black polymer at the bottom of the visor. The base Commando helmet has a HUL already attached, making it one of only three base helmets to have an attachment, the others being the Beta-5 Operator helmet, which has a goggle-like attachment, and the EOD helmet, which has a CBRN module.
Two upgrades are available for the helmet. The first, CBRN/CNM, replaces the HUL attachment with a CBRN apparatus featuring an External Command Network Module on the left side. The second, UA/FC-I, adds an up-armor plate with a third-generation Hardened Uplink Module on the right side and a Command Network Module on the left side.
Cost: 40,000 cR, Commander
It is characterized by a large curved plate of armor set on the standard base, which connects it to the Spartan's shoulder. It is noticeably large and is placed high on the Spartan's arm.
