OPERATOR-class Mjolnir

OPERATOR-class Mjolnir, is a MJOLNIR armor variant originally designed by Chalybs Defense Solutions, with the GEN2 version being manufactured by the Naphtali Contractor Corporation.

Overview
The Mark V variant of the armor was designed for use by Spartan operators within the ONI Beta-5 Division's Asymmetrical Action Group (AAG). The standard version of the helmet features a B5D-O/Optics suite, which is mounted on the forehead. The UA/HUL variant replaces the standard optics suite with an up-armor plate featuring a Hardened Uplink Module on the left side. Another variant, which is issued to unit commanders, features Command Network Module-Improved on the right side. The Operator systems's shoulder pauldrons are simply armored bands mounted on the user's base shoulder guards, with two string-like attachments descending from the bottom. There is a geometrical pattern emblazoned on the plate as well.

After the first wave of GEN2 systems, based on requests of veteran Spartan-II and Spartan-III operatives, the UNSC Ordnance Commission considered reassessing a refined and upgraded version of the Mark V EVA-class Mjolnir, specifically the customized suit worn by Emile-A239 complete with the death's head engraving on the visor. This led to the creation of the WRATH-class Mjolnir with the left shoulder pad based off the Mark V Operator's shoulders.

Development history
While the non-Spartan members of the Asymmetrical Action Group wear their own standard-issue armor, the Beta-5 Division contracted Chalybs Defense Solutions to develop a MJOLNIR variant designed to improve the performance of the AAG's Spartan personnel. The armor, which was jointly developed at the Beta-5 Division Ordnance Testing Facility and tested at Chalybs Testing Preserve, can provide the wearer with detailed, on-the-fly intelligence through secure transmissions that can bypass most Covenant security networks.

Usage
The Mark IV variant of the armor was worn by Joshua-029 during the Battle of Sigma Octanus IV.

Overview
The reactor of the GEN2 version of the OPERATOR armor is a low-set reactor pack. The helmet has a PV-20, which is a set of dual-locked rebreathers generally worn by pilots. The visor has an open visor view-plate for increased range of spectrum, with sensor fusion software that ties the info into the visor to be finalised. The chest has external harness bracers. Twin-release cables on the chest route energy expenditure to reserve systems.

Development history
Sometime after the Fall of Reach, the Operator armor was taken over by the Naphtali Contractor Corporation, after the abandonment of all CDS facilities on Meridian, and was tested extensively with live fire exercises in the NCC's abandoned shipyards on the outskirts of Abilene. Unlike its predecessor, it optimizes a Spartan for the operation and control of vehicles.

Usage
Operator armor has proven itself an adaptable combat ensemble in Spartan service, utilized by both pilots and force reconnaissance operatives.
