Shepherd led a U.S. military convoy to transport two Royal Air Force officers back to their unit and arrive at their destination just before 12.00 p.m. In 11.15 a.m. in the United Kingdom, First Lieutenant Chris Tanner arrived at Lower Heyford Air Force Base's drone control room where Peter Dennon told him that Shepherd wants to talk to him. Tanner received the call from Shepherd, who was berating him for not informing the RAF Command on his orders, revokes his weekend pass as punishment. Tanner controlled a MQ-1 Predator drone flying above in Kajaki Province to provide aerial reconnaissance to Shepherd's team. After Tanner finished his mission and was about to fly the drone away, someone hacked his drone; Tanner could only watch as the drone locked on to the armored vehicle. Tanner contacted Shepherd and warned him about the incoming attack and tried to get the team to clear the area. Despite Tanner's frantic warnings, the drone fired a AGM-114 Hellfire missile and destroyed the armored vehicle, killing twoAmerican and twoBritish soldiers instantly.
