Despite repeated assurances from President Obama and military leaders that the U.S. would not send uniformed military personnel into Libya, four U.S. service members arrived on the ground in Tripoli over the weekend.
According to Pentagon spokesman Capt. John Kirby, the four unidentified troops are there working under the State Department’s chief of mission to assist in rebuilding the U.S. Embassy.
Kirby noted the embassy in Tripoli was badly damaged during the conflict between Muammar Qaddafi’s forces and the rebels.
Two of the military personnel are explosive-ordnance experts who will be used to disable any explosives traps left in the embassy. The other two are “general security,” according to Kirby.
