'''COS-class Mjolnir''' is an experimental variant of [[MJOLNIR Powered Assault Armor]], which was approved for testing on [[ANVIL Station]].{{Ref/Reuse|Desc}}

==Overview==
===Design details===
The COS-class bears a notable resemblance to the GEN2 models of the [[GUNGNIR-class Mjolnir]], sharing near-identical torso chassis', shoulder pauldrons and forearm gauntlets.

===Development history===
COS-class was built in the skunkworks departments of ANVIL Station.{{Ref/Site|Id=CFHotDrops|D=28|M=2|Y=2021|URL=https://www.halowaypoint.com/en-us/news/hot-drops|Site=Halo Waypoint|Page=Canon Fodder - Hot Drops}} The suit was also tested on ANVIL Station, where the station's cyberintrusion specialists used the armour to test experimental counter-intrusion modules.{{Ref/Game|Id=Desc|MCC|''[[Halo 3]]'' [[Armor customization (Halo 3)|customisation]] menu}}

==Production notes==
{{stub|section=yes}}
The COS armor set was originally created as a useable [[Armor customization (Halo Online)|armor permutation]] for ''[[Halo Online]]'', a cancelled ''Halo 3''-derived [[multiplayer]] game developed by [[Saber Interactive]] and Innova Systems which was intended to be released exclusively in Russia for the PC. After the game's cancellation in [[2016]], the armor was one of [[Armor customization (Halo 3)#Halo: The Master Chief Collection|six sets]] added to ''Halo 3'' in ''The Master Chief Collection'' as part of the game's [[Series 6: Raven|sixth season]] in [[2021]].

The suit set bears a notable heavy resemblance to the [[GUNGNIR-class Mjolnir]] seen in ''[[Halo 4]]'' and ''[[Halo 5: Guardians]]'', with the suit's internal game filenames even referring to it as such. In the original ''Halo Online'' game, the suit was known as GUNGNIR in the alpha builds, though was later changed to the name of Kaladbolg.

==Trivia==
*The armor's originally altered designation of "Kaladbolg" references "[[Wikipedia:Caladbolg|Caladbolg]]", a mythical, two-handed sword wielded by [[Wikipedia:Fergus mac Róich|Fergus mac Róich]], of Irish mythology.
*In the real-world, COS is a military acronym, standing for Cyber Operations Specialist - the role employed by the COS armor.{{Ref/Site|URL=https://www.todaysmilitary.com/careers-benefits/careers/cyber-operations-specialists|Site=Today's Military|Page=Cyber-Operations Specialists|D=14|M=7|Y=2021}}
