When the U.S. Embassy in Kabul closed, the last individuals to secure it were not civilians or even U.S. military, but the quiet and dynamic special agents of the Diplomatic Security Service (DSS) of the State Department.
These federal law enforcement officers are the professionals conducting personnel recovery missions in Kabul (finding and bringing U.S. citizens and others to the airport), protecting U.S. personnel, coordinating with the Department of Defense (DOD) and trying to create a secure zone at the airport with limited resources.
When, on Thursday, a terrorist attack at the Kabul airport killed U.S. Marines deployed there to help keep residents and travelers safe, these agents were the ones in charge of the emergency response.
Diplomatic security efforts began during the First World War. DSS was formally established in 1985 in response to the deadly 1983 bombings of the U.S. Embassy and Marine barracks in Beirut, Lebanon. Today, its main duties are to secure the integrity of U.S. travel documents (namely against visa and passport fraud), to facilitate U.S. foreign policy by protecting diplomatic assets (including every U.S. Embassy and U.S. Consulate), personnel, information around the world and to aid in counterintelligence.
