'''SECURITY-class Mjolnir''', also designated as the '''MJOLNIR Powered Assault Armor/M variant''', is a [[MJOLNIR Powered Assault Armor|MJOLNIR armor]] variant adapted from an infiltration prevention suit designed by [[Misriah Armory]].{{Ref/Reuse|h3h}}  

The Security variant was first manufactured in the [[Misriah Armory]] facility on [[Mars]] in [[2528]].{{Ref/Game|Id=HR|HR|Armor permutations (Halo: Reach)|Armory|Detail=Security - Shoulders Description|Quote=The Supplemental Armor, Pauldron, MJOLNIR(M) variant was originally manufactured in 2528.}} After [[MJOLNIR Powered Assault Armor/Mark V|Mark V]] was released, this armor was adapted to its use. Like most MJOLNIR variants, the later model of the Security helmet had been upgraded to be compatible with all MJOLNIR Mark VI variants.{{Ref/Reuse|h3s}} The Mark V iteration of the helmet is compatible with [[CBRN module|CBRN]], [[Armor accessories/UA|UA]], [[Command Network Module|CNM]] and [[Hardened Uplink|HUL]] attachments.

After the first wave of [[MJOLNIR Powered Assault Armor (GEN2)|GEN2]] systems, based on requests of veteran [[Spartan-II]] and [[Spartan-III]] operatives, the [[UNSC Ordnance Commission]] considered reassessing a refined and upgraded version of the [[EVA-class Mjolnir]] suit. This led to the creation of the [[WRATH-class Mjolnir]] where its right shoulder pad is based off the Mark V Security shoulders.{{Ref/Game|H5G|Armor permutations (Halo 5: Guardians)|Armor Permutations|Detail=WRATH - Helmet Description|Quote=Formally an upgrade of existing Mark V EVA suits, the WRATH project was actually a cover to develop a new Mjolnir variant specifically tailored to the needs of future Headhunter teams.}}{{Ref/Site|Id=CFNoble|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-noble-intentions|Site=Halo Waypoint|Page=Canon Fodder - Noble Intentions|D=8|M=7|Y=2016}} SECURITY [GEN1] helmets continued to be used by Misriah Armory's executive protection teams after the Covenant War.

The Security Mark V shoulder pauldrons return in ''[[Halo Infinite]]'', available under the [[Armor accessories/SAP|SAP category]] for the [[Mark V(B)]] core. The Security GEN3 helmet—alongside an exclusive helmet attachment, was introduced as part of the Aquahex Super Bundle at the start of [[Season 03: Echoes Within]]. [[Season 05: Reckoning]] added the Mark V Security helmet and a new helmet attachment.

==Production notes==

*The SECURITY-class helmet (as well as the Mark VI version's pauldrons) is based on that worn by the protagonist of the ''[[Marathon]]'' series, who is a security officer on the eponymous vessel. The ''Marathon'' logo is featured prominently on the Mark VI version of the helmet (just above the visor) in ''Halo 3''. The Mark V Security helmet in ''Halo: Reach'' and ''Halo 5: Guardians'' lacks the symbol, likely due to intellectual property concerns (as [[Bungie]] retained the ''Marathon'' IP after leaving Microsoft). However, the [[Forerunner symbols#Reclaimer|Reclaimer symbol]] (a modified version of the ''Marathon'' logo) appears on the GEN2 version of the helmet in ''Halo 5: Guardians''.

*The ''[[Halo Encyclopedia (2009 edition)]]'' erroneously states the Security armor was manufactured in 2543 rather than 2528.{{Ref/Book|Enc09|Page=92}}

*During the development of ''Halo 5: Guardians'', the GEN2 Security armor was designated "''A067''" when it was conceived.{{Ref/Site|Id=CFSustained|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-sustained-glass|Site=Halo Waypoint|Page=Canon Fodder - Sustained Glass|D=9|M=7|Y=2021}}
