CBRN module

From Halopedia, the Halo wiki

The CBRN module (right) with a Command Network Module (left).

The CBRN module, short for the Chemical, Biological, Radiological and Nuclear module, is an external attachment for several MJOLNIR Mark V and [GEN3] helmets.[1][2]

Overview[edit]

Design details[edit]

CBRN modules are typically filter attachments worn externally on the "mouth" area of helmets.[3]

Usage[edit]

The CBRN modules are employed for operations in hazard zones, wherein chemical, biological, radiological and nuclear threats are present.[4]

Known modules[edit]

The CBRN module has multiple observed modules, each with its own distinct physical appearance.

AML 201-1[edit]

The AML 201-1 module on the Lechuza helmet.

Manufactured by Watershed Division, the AML 201-1 CBRN module contain an unknown type of programmable matter and hives for nanomachine swarms that augment a Spartan's respiratory efficiency. The analysis process is complicated by how the nanomachines become inert outside the helmet or host Spartan.[5]

MK12T2 TRAILWATCH[edit]

The MK12T2 TRAILWATCH module on the War Master helmet.

Manufactured by Lethbridge Industrial, the MK12T2 TRAILWATCH module features filters and backup life support components certified at the Lethbridge Combat Fields.[6]

MK17 MOD1 KUZNETS[edit]

Manufactured by Korolev Heavy Industries, the MK17 MOD1 KUZNETS module is specialized for the interiors of Forerunner megastructures.[7]

MK55[edit]

The MK55 on the Commando helmet.

Manufactured by Imbrium Machine Complex, the MK55 module is a filter attachment used during extended operations in environments contaminated by chemical agents, radionuclides, and biological hazards.[3]

The MK55 module has been observed to be compatible with the following helmets:

MK59E GLANCE[edit]

The MK59E GLANCE module on the Aviator helmet.

Manufactured by Imbrium Machine Complex, the MK59E GLANCE module is designed for hazardous operations in the tainted atmosphere of damaged space station and warships. The MK59E GLANCE module has been observed to be compatible exclusively with the AVIATOR-class Mjolnir helmet.[12]

MOD-P[edit]

The MOD-P CBRN module on the Morrigan helmet.

Manufactured by Naphtali Contractor Corporation, the MOD-P CBRN module is designed to maximize endurance and efficacy in various atmospheric conditions, or to aid Spartans in tracking specific biochemical signatures. The MOD-P CBRN module has been observed to be compatible exclusively with the MORRIGAN-class Mjolnir helmet.[13]

EOD-style module[edit]

The CBRN module on the standard EOD helmet.

This EOD-style module is a pair of filter attachments on either side of the helmet. It is employed on the standard Mark V EOD-class Mjolnir helmet, but it could be removed for other helmet attachments.[14]

This module has been observed to be compatible with the following helmets:

AKIS-style module[edit]

The CBRN module on the AKIS helmet.

The AKIS-style module was developed in parallel to the AKIS helmet, and has only been observed as compatible to the AKIS helmet.[16]

Gameplay[edit]

The CBRN modules serve as cosmetics and have no impact on gameplay.

Halo: Reach[edit]

Two of the CBRN modules are available as attachments on several helmets in the armor permutations of Halo: Reach. The device is priced at different levels of Credits, depending on the base helmets. In Halo: The Master Chief Collection, the same CBRN-attached helmets are unlockable in Season 1: Noble, while the AKIS-style module added in Series 5: Anvil.

Halo 5: Guardians[edit]

A CBRN module is featured on the EOD GEN1 helmet, which is one of the helmets that could be acquired through the Classic Helmet REQ Pack in Halo 5: Guardians .

Halo Infinite[edit]

CBRN module attachments are available as customization options in Halo Infinite.

Production notes[edit]

"CBRN" stands for chemical, biological, radiological, and nuclear, and is pronounced "C-BURN". It is the same abbreviation used in real life, hence its association with the HAZOP armor permutation.
