When terrorists attacked the U.S. consulate in Benghazi, Libya, on Sept. 11 of this year and killed the U.S. ambassador and three other Americans, there were no U.S. Marines deployed in Libya to defend U.S. diplomats, diplomatic facilities and classified information and equipment. However, says the State Department, a Marine Security Detachment was deployed on that day to carry out those duties at the U.S. Embassy in Bridgetown, Barbados.
