Navy Relieves Naval Information Operations Command, Colorado Commanding Officer

[Tony]

FORT MEADE, Md. – The commanding officer of Navy Information Operations Command (NIOC) Colorado was relieved April 3 due to a loss of confidence in his ability to command.

Capt. Chelsey Zwicker, commodore of Naval Information Operations Command Pacific, relieved Cmdr. Christopher Johnson of his duties as NIOC Colorado’s commanding officer. NIOC Colorado is a subordinate command of Naval Information Operations Command Pacific, which is headquartered at Joint Base Pearl Harbor-Hickam in Hawaii.

The Navy maintains the highest standards for commanding officers and holds them accountable when those standards are not met.

Cmdr. Mark Tuner, the Naval Information Forces Liaison Officer to U.S. Fleet Cyber Command, will temporarily serve as NIOC Colorado’s commanding officer until a permanent replacement is designated.

Johnson assumed command of NIOC Colorado in May 2023. He has been temporarily reassigned to U.S. Fleet Cyber Command.

U.S. Fleet Cyber Command plans, coordinates, and conducts a full spectrum of cyberspace operational activities required to ensure freedom of action across all Navy warfighting domains in, through and from cyberspace, while denying adversaries the same capability.
