HAZOP-class Mjolnir

"Some operations are considered hazardous even for a fully armored Spartan"

- Description of the HAZOP helmet.

HAZOP-class Mjolnir (Hazard Operability), is a MJOLNIR Powered Assault Armor, is a MJOLNIR armor variant originally designed by the Materials Group, with the GEN2 version being manufactured by Acheron Security.

Overview
The HAZOP armor utilizes a specialized material that helps protect the user normal from heightened exposure to radiation that normal Mjolnir suits cannot. HAZOP also employs a unique technology to process and manufacture oxygen in highly toxic conditions.

The Mark V HAZOP armor includes a helmet and a shoulder piece.

Development history
Early on in the Human-Covenant War prototypes of the suits were created for use for where the UNSC had to battle the Covenant head on in environments that were chemically volatile for average Mjolnir suits.

Overview
The helmet has a view-path stabilizing visor with AZ-T sensor array, with a modified rebreather castor lines. The chest contains a redundant oxygen filtration system (Unit A-7X43), with the reactor pack is a firm-case fusion pack to simplify withdrawal process. The armor also has the most advanced radiation shielded underarmor mesh currently in production by the UNSC.

Development history
Templates for the GEN2 were acquired by Acheron Security from the Materials Group in 2553, where a number of advances were engineered to enhance protective operability during EVA deployment while outside a vehicle in slipspace.

Acheron Security re-architected the GEN2 HAZOP-class armor systems explicitly for extended operations within exotic and environmentally hazardous locales.

Usage
While its process of operability during EVA deployment while outside a vehicle in slipspace is slow, many Spartans have adopted the framework of HAZOP.
