- —Description of the HAZOP helmet.
The MJOLNIR Powered Assault Armor/HAZOP (Hazard Operability), is a variant of the MJOLNIR Powered Assault Armor. The HAZOP variant was first developed for the MJOLNIR Mark V Powered Assault Armor. The variant was carried over to the GEN2 system, and is now manufactured and battle-tested at Gdynia, Mars by Acheron Security.
 GEN1 Characteristics
 Helmet Characteristics
Two upgrades are availible for the helmet, the first adds a Chemical, Biological, Radiological, and Nuclear Module with a Hardened Uplink Module on the right side (CBRN/HUL), and the second adds the unnamed attachment similar to night vision goggles found on the Operator variant with a Command Network Module on the left side (incorrectly called a CNM-I, and instead should be called (unknown)/CNM).

It was developed by Acheron Security. When its contract was transferred from the Materials Group, Acheron Security re-architected the GEN2 HAZOP-class armor systems explicitly for extended operations within exotic and environmentally hazardous locales. Templates for the GEN2 were acquired by Acheron Security in 2553, where a number of advances were engineered to enhance protective operability during EVA deployment while outside a vehicle in slipspace. The armor contains redundant oxygen filtration systems, modified rebreather caster lines, and the most advanced radiation shielded underarmor mesh currently in production by the UNSC.
