“Tyrone Woods and Glen Doherty, were part of a Global Response Staff or GRS that provides security to CIA case officers and provides countersurveillance and surveillance protection. They were killed by a mortar shell at 4 a.m. Libyan time, nearly seven hours after the attack on the Consulate began — a window that represented more than enough time for the U.S. military to send back-up from nearby bases in Europe, according to sources familiar with Special Operations. Four mortars were fired at the annex. The first one struck outside the annex. Three more hit the annex.”
