Marine Security Guards
In addition to wanting to meet and overcome the challenges, physical and mental, of earning the title "Marine," one reason Marines give for joining the Corps is a chance for travel and adventure. Perhaps no other billet in the Marines, or any service, can live up to this desire more than Marine Security Guard duty.
Marine Security Guards are responsible for providing security at about 125 U.S. embassies and consulates around the world. Those on MSG duty are primarily responsible for embassies' interior security, normally the lobby or main entrance. Guards are trained to react to terrorist acts as well as a variety of emergencies such as fires, riots, demonstrations and evacuations.
