Marine Corps Intelligence Schools are located across three major detachments – Dam Neck and Oceana, VA as well as Newport, RI. These schools are interservice schools, meaning they are attended by airmen, soldiers, and sailors as well. Although MCIS provides primary support to regional subordinate training units, it continues to execute the functional mission of serving as the focal point for all Marine Corps Intelligence training and education issues regarding MAGTF Intelligence, Signals Intelligence, and Remote Sensor Operator military occupation fields.

The Marine Detachment at Virginia Beach offers over a dozen formal programs of instruction offering over 50 course sessions per year with a student throughput of over 1,000 Marines, Sailors, Soldiers, Airmen, and civilians annually. They are charged with the responsibility for both entry level and advanced level training of all Marine Corps intelligence officers as well as both basic and advanced Intelligence Analysis Courses, Sensor Employment, and Intelligence Systems training.
