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===

==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.
