COS-class Mjolnir is an experimental variant of MJOLNIR Powered Assault Armor, which was approved for testing on ANVIL Station.[1]
Overview
Specifications
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.[2] The suit was also tested on ANVIL Station, where the station's cyberintrusion specialists used the armour to test experimental counter-intrusion modules.[1]
In-game information
The COS armor set was first introduced into Halo 3's MCC port along with six other new armor sets, as part of Season 6: Raven. It was never available in Halo 3 for Xbox 360.[3]

Production notes
This section needs expansion. You can help Halopedia by expanding it.
The COS armor set was originally created as a useable 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 six sets added to Halo 3 in The Master Chief Collection as part of the game's 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
In the real-world, COS is a military acronym, standing for Cyber Operations Specialist - the role employed by the COS armor.[4]
