The Marine Corps Intelligence Activity provides tailored intelligence and services to the Marine Corps, other services, and the Intelligence Community based on expeditionary mission profiles in littoral areas. It supports the development of service doctrine, force structure, training and education, and acquisition.
MCIA determines what missions the Corps needs to carry out as well as who will need to be trained for that mission. MCIA is in partnership with Office of Naval Intelligence and Coast Guard Intelligence in the National Maritime Intelligence Center and at Marine Corps Base Quantico in Quantico, Virginia.
