A Marine Security Guard (MSG), also known as a Marine Embassy Guard, is a member of the Marine Corps Embassy Security Group (formerly Marine Security Guard Battalion), a battalion-sized organization of the United States Marine Corps (USMC) whose detachments provide security at American embassies, American consulates and other official United States Government offices such as the United States Mission to NATO in Brussels, Belgium. The Marine Security Guard was designated MOS 8151, though this has changed to MOS 8156. The USMC has a long history of cooperation with the U.S. State Department, going back to the early days of the country. From the raising of the American flag at Derna, Tripoli, and the secret mission of Archibald H. Gillespie in California, to the Boxer Rebellion at Peking, Marines have served many times on special missions as couriers, as guards for embassies and delegations, and to protect American citizens in unsettled areas. The formal and permanent use of Marines as security guards began with the Foreign Service Act of 1946, which authorized the Secretary of Navy to, upon the request of the Secretary of State, assign Marines to serve as custodians under the supervision of the senior diplomatic officer at a diplomatic post. The first joint Memorandum of Agreement was signed on 15 December 1948 regarding the provisions of assigning Marines overseas. Trained at the Foreign Service Institute, the first Marines arrived at Tangier and Bangkok in early 1949. The Marine Corps assumed the primary training responsibility in November 1954. The authority granted in the Foreign Service Act of 1946 has since been replaced by 10 U.S.C. § 8183 and the most recent Memorandum of Agreement was signed in August 2008. Although embassy duty is a crucial aspect of the Marines mission with a long tradition, the Corps is only budgeted to train and maintain a limited cadre of guards to cover over 100 embassies worldwide. In response to the 2012 Benghazi attack, Congress ordered a near doubling of Marine Security Guards in the midst of a post-war drawdown in overall USMC numbers.
