- —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
All current HAZOP Armor Permutations in Halo: Reach
 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).
 Shoulder Characteristics
The HAZOP armor also includes a shoulder piece, which costs 500 cR. It is about the size of the FJ/PARA shoulders and is shaped like a curved "H".
 GEN2 Characteristics
|| Manufactured and battle-tested just outside of the city of Gdynia on Mars.
