The Marine Corps Intelligence Activity (MCIA) 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.
The MCIA can be tasked to provide expeditionary warfare intelligence to support any national, theater, or operational command in the U.S. Armed Forces. MCIA's analysis and production support not only the Marine Corps, but also the national decisionmaker, theater commander, and operational warfighter. MCIA is a major production organization for expeditionary intelligence and cultural intelligence.
