CBRN module
From Halopedia, the Halo wiki
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]
Manufactured by Watershed Division, the AML 201-1 CBRN module contains 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]
AML 255[edit]
The AML 255 CBRN module, manufactured by Watershed Division, features improved life maintenance modules that enhance a Spartan's operational longevity in toxic environments. It is most notably compatible with the Cohort helmet, but it can also be used with the Celox and Rampart helmets.[6]
FIM-A[edit]
The Field Improvised Module-A (FIM-A) is an ad hoc configuration built with off-the-shelf parts manufactured by Materials Group. Attached to the top and the sides of the Armet helmet, the modules' purpose is for hazard communications.[7]
MK12T2 TRAILWATCH[edit]
Manufactured by Lethbridge Industrial, the MK12T2 TRAILWATCH module features filters and backup life support components certified at the Lethbridge Combat Fields.[8]
MK17 MOD1 KUZNETS[edit]
Manufactured by Korolev Heavy Industries, the MK17 MOD1 KUZNETS module is specialized for the interiors of Forerunner megastructures.[9]
MK40[edit]
Manufactured by Materials Group, the MK40 module is a pair of filter attachments on either side of the helmet. They feature a shock-hardened filtering system and provide supplemental life support.[10] It is employed on the standard Mark V EOD-class Mjolnir helmet, but it could be removed for other helmet attachments.[11]
This module has been observed to be compatible with the following helmets:
MK55[edit]
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:
