The Secretary of Defense recognized the significance of the cyberspace domain to national security, and directed the establishment of U.S. Cyber Command (USCYBERCOM) as a sub-unified command under U.S. Strategic Command (USSTRATCOM). USCYBERCOM’s primary objective is to plan, coordinate, integrate, synchronize and conduct activities to: direct the operations and defense of specified Department of Defense information networks and; prepare to, and when directed, conduct full spectrum military cyberspace operations in order to enable actions in all domains, ensure US/Allied freedom of action in cyberspace and deny the same to the adversary. In response, the Marine Corps established Marine Forces Cyberspace Command (MARFORCYBER) in October 2009 (this was complemented by the establishment of the Navy’s U.S. Fleet Cyber Command (FLTCYBER), Army Cyber Command (ARCYBER), and Air Force Cyber Command (AFCYBER).


(1) Commander, Marine Corps Forces Cyberspace Command (COMMARFORCYBERCOM), as the Marine Corps service component commander for the Commander, U.S. Cyber Command (CDRUSCYBERCOM), represents Marine Corps capabilities and interests; advises CDRUSCYBERCOM on the proper employment and support of Marine Corps forces; and coordinates deployment, employment, and redeployment planning and execution of attached forces.

(2) COMMARFORCYBERCOM enables full spectrum cyberspace operations, to include the planning and direction of Marine Corps Enterprise Network Operations (MCEN Ops), defensive cyberspace operations (DCO) in support of Marine Corps, Joint and Coalition Forces, and the planning and, when authorized, direction of offensive cyberspace operations (OCO) in support of Joint and Coalition Forces, in order to enable freedom of action across all warfighting domains and deny the same to adversarial forces.

(3) COMMARFORCYBERCOM has direct operational control of Marine Corps Cyberspace Warfare Group (MCCYWG) and Marine Corps Cyberspace Operations Group (MCCOG) to support mission requirements and tasks. Additionally, the Marine Corps Information Operations Center (MCIOC) will be in direct support of MARFORCYBER for full spectrum cyber operations.
