'''CIO-class Mjolnir''' (Counter Intelligence Operator) is a variant of the [[MJOLNIR Powered Assault Armor (GEN2)|MJOLNIR Powered Assault Armor [GEN2]]] manufactured by [[Acheron Security]].{{Ref/Game|Id=H4 Armory|H4|[[Armor customization (Halo 4)|Armory]] description}}

==Overview==
===Design details===
The CIO helmet has a tricloptically fixed multi-spectral imaging array, also known as a transponder array.{{Ref/Reuse|H4EVG}}{{Ref/Generic|Id=H4LE|[[Halo 4 Limited Edition]]|[[Infinity Briefing Packet]]}} The neural interface bypasses in the CIO helmet allow the wearer to create custom synesthesis profiles to remap the suit sensors with their own senses.{{Ref/Game|Id=H5 Armory|H5G|[[Armor customization (Halo 5: Guardians)|Armory]] description}} The suit also has a galvanized sensory suite that rivals nearly all other similar service packages.{{Ref/Reuse|H4LE}}

The chest has a modular sensory suite, and a silhouette dampener for motion sensor circumvention.{{Ref/Reuse|H4EVG}}
 
===Development history===
After seeing the need for highly trained, heavily armored personnel to be deployed deep into enemy-controlled territory, [[Acheron Security]] developed and manufactured the CIO-class armor, with its main focus on espionage rather than lethality. The armor was tested at the [[Acheron Trauma Sim]],{{Ref/Reuse|H4EVG}} and was designed to operate in the Martian territory of Acheron Fossae.{{Ref/Reuse|H4 Armory}}

===Usage===
Though rarely seen, it is utilized by a handful of [[SPARTAN-IV]]s and Counter-Intelligence Operators for intel acquisition and strategic data conveyance deep within enemy territory, often those who endure tier-nine theaters.{{Ref/Reuse|H4EVG}}

Several CIO-armored Spartans were deployed to [[Terceira]], where they captured and transmitted information crucial to the recovery of the colony from [[Insurrectionist]] forces.{{Ref/Reuse|H4EVG}}

CIO is also used during information denial missions, hunting down enemy scouts and preventing them from acquiring data of tactical or strategic importance.{{Ref/Reuse|H5 Armory}}

==In-game information==
===''Halo 4''===
CIO was first introduced as an [[Armor customization (Halo 4)|armor set]] in ''[[Halo 4]]''. The armor has three available skins; Web (WEB), Ruin (RUIN) and Rush (RUSH).

===''Halo 5: Guardians''===
The CIO set returns as an [[Armor customization (Halo 5: Guardians)|armor permutation]] in ''[[Halo 5: Guardians]]'', being unlockable through the [[Requisition system]]. The body armor includes the [[RICOCHET-class Mjolnir|Ricochet]] forearms, and [[RECRUIT-class Mjolnir|Recruit]] legs. Contrasting its ''Halo 4'' iteration's multitude of skins, the CIO set of ''Halo 5'' has no alternate skins.

==Production notes==
{{Main|Cut Halo 4 customization}}
Promotional images for the "Ruin" skin also included the pattern on the [[Inner-plated]] wrist armor and [[Over-locking]] leg armor. The final release version of the "Ruin" skin only added the skin on the CIO's helmet, chest, and shoulder armor, leaving out the wrists and legs.
