Please Note: Not all overseas locations are considered "deployment" locations. For example, embassies and Okinawa, though located overseas, are actually permanent duty stations (PDS). Countries where troops are in place during engagements or combat zones are typically referred to as deployment locations.
One of the most visible functions of the United States Marine Corps is the Marine Special Duty Detail. This is the force that provides Embassy security duty for United States Facilities around the world.
Marine Security Guards provide security services to selected Department of State Foreign Service posts to prevent the compromise of classified material and equipment and to provide protection for United States citizens and United States Government property. The Marine Security Guard Battalion exercises command, less operational control, of these Marines, in that it is responsible for their training, assignments, administration, logistical support, and discipline.
