“On December 3 [2001], a CIA Jawbreaker intelligence team operating near the town of Gardez, in eastern Afghanistan, picked up the first ‘hard’ intelligence that bin Laden was in fact at Tora Bora [Afghanistan]. A U.S. Army Grey Fox SIGINT [signals intelligence] team near Gardez intercepted some al Qaeda walkie-talkie radio traffic that confirmed he was personally leading the al Qaeda forces.”
