===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}}
