Marine Security Guard Battalion

• Origins in 1948: The Marine Security Guard Battalion (MSG Bn) was formally established in 1948, following a request from the U.S. State Department for Marines to protect American embassies and consulates worldwide. • Global Presence: MSG Bn maintains detachments at over 150 U.S. diplomatic posts in more than 135 countries, making it one of the most globally dispersed Marine units. • Call Sign "Watchstanders": Marines in the MSG Bn are often referred to as "Watchstanders," reflecting their 24/7 duties guarding American diplomatic missions. • Rigorous Selection and Training: Marines must complete a competitive selection process and a seven-week school at Marine Corps Base Quantico, Virginia, before joining the MSG Bn. • Notable Action in Tehran: During the 1979 Iran hostage crisis, MSG Marines attempted to defend the U.S. Embassy in Tehran, with several taken hostage and later released after 444 days. • Women in the Ranks: In 1997, the first female Marines graduated from the MSG School and began serving in the battalion, breaking a longstanding gender barrier. • Special Ceremonial Uniform: MSG Marines are often recognized for their distinctive dress blue uniforms, which are worn during official functions and ceremonies at embassies. • Silver Trident: Upon graduation, MSGs are awarded the Marine Security Guard badge, often called the "Silver Trident," symbolizing their elite status. • Fallen Heroes: The battalion has suffered losses, including during the 1983 U.S. Embassy bombing in Beirut, where eight MSG Marines were killed in the line of duty. • Annual MSG Ball: Many embassies and consulates host an annual Marine Corps Birthday Ball, where Marines and embassy staff celebrate the history and camaraderie of the MSG mission.
