The '''CBRN module''', short for the '''[[Wikipedia:Chemical, biological, radiological, and nuclear|Chemical, Biological, Radiological and Nuclear]] module''', is an external attachment for several [[MJOLNIR Powered Assault Armor/Mark V|MJOLNIR Mark V]] and [[MJOLNIR Powered Assault Armor (GEN3)|[GEN3]]] helmets.{{Ref/Game|HR|Armor permutations (Halo: Reach)|Armory}}{{Ref/Site|Id=xbox|D=14|M=6|Y=2021|URL=https://www.xbox.com/en-GB/games/halo-infinite|Site=Xbox|Page=Halo Infinite}}

==Overview==
===Design details===
CBRN modules are typically filter attachments worn externally on the "mouth" area of helmets.{{Ref/Reuse|mk55}}

===Usage===
The CBRN modules are employed for operations in hazard zones, wherein [[Wikipedia:Chemical, biological, radiological, and nuclear|chemical, biological, radiological and nuclear]] threats are present.{{Ref/Game|Id=cbrn|HR|Armor permutations (Halo: Reach)|Armory|Detail=AKIS, CQC, and GUNGNIR - CBRN Helmet Descriptions|Quote=For operations in hazard zones.}} 

==Known modules==
The CBRN module has multiple observed modules, each with its own distinct physical appearance.
===AML 201-1===
[[File:HINF AML 201-1 CBRN Helmet Attachment Icon.png|thumb|150px|The AML 201-1 module on the [[LECHUZA-class Mjolnir|Lechuza]] helmet.]]
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.{{Ref/Game|Id=aml201|HINF|Armor customization (Halo Infinite)|Armor Hall|Detail=AML 201-1 CBRN - Helmet Attachment Description|Quote=These modules contain an unknown type of programmable matter and hives for nanomachine swarms that augment a Spartan's respiratory efficiency.

==Gameplay==
The CBRN modules serve as cosmetics and have no impact on gameplay.
===''Halo: Reach''===
Two of the CBRN modules are available as attachments on several helmets in the [[Armor customization (Halo: Reach)|armor permutations]] of ''[[Halo: Reach]]''. The device is priced at different levels of [[Credit]]s, 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]].

==Production notes==
"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 [[MJOLNIR Powered Assault Armor/Mark V/HAZOP|HAZOP]] armor permutation.
