Semper in Proelio, Latin for "Always in Battle", is not only our motto, but the reality of cyberspace. Cyberspace is and always will be a contested domain. Cyberspace intersects with and enables all operational missions in all domains. Always Faithful, Always in Battle. Mission: To conduct full spectrum cyberspace operations, to include operating and defending the Marine Corps Enterprise Network, conducting defensive cyberspace operations within the Marine Corps Enterprise Network and Joint Force networks, and when directed, conducting offensive cyberspace operations in support of Joint and Coalition Forces; in order to enable freedom of action across all warfighting domains, and deny the same to adversaries.
