The Marine Corps Intelligence Activity (MCIA), is a field activity of Headquarters, U.S. Marine Corps and a member of both the Defense Intelligence Enterprise and the United States Intelligence Community. The MCIA describes itself as: "a vital part of military intelligence 'corporate enterprise,' and functions in a collegial, effective manner with other service agencies and with the joint intelligence centers of the Joint Chiefs of Staff and Unified Commands."
The Marine Corps Intelligence Activity mission is to provide intelligence services to the Marine Corps and the U.S. Intelligence Community. These services are 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 Office of Coast Guard Intelligence in the National Maritime Intelligence-Integration Office and at Marine Corps Base Quantico in Quantico, Virginia.Template:USMC-stub
