Before being assigned to a Foreign Service post, a Marine accepted into the MSG program must successfully complete a training program located at the Marine Corps Embassy Security Group (MCESG), which is located at Marine Corps Base Quantico, Virginia. Marine Security Guard duty is one of a few special duty assignments available to qualified Marines. Marine Security Guard duty can be dangerous; there have been instances where Marines have been killed during this duty (most recently, Cpl Steve Crowley in 1979, Cpl Robert V. McMaugh in 1983, and Sgt Jesse Aliganga in 1998). Embassy duty is a crucial aspect of the Marine Corps' mission with a long tradition, the Corps is currently tasked to train and maintain a cadre of guards to cover 181 embassies and consulates worldwide with the ability to augment assigned forces as necessary.
