Lt. Col. Wade Karren, right, assumes command of the 11th Bomb Squadron from Col. Brandon Parker, 2nd Bomb Wing vice commander, during the squadron’s assumption of command ceremony at Barksdale Air Force Base, La., Sept. 14, 2015. The ceremony was part of a military tradition that gives service members the opportunity to witness their new leader's assumption of command. Karren did not travel far for this assignment, as he was serving as the 20th Bomb Squadron director of operations, also at Barksdale. (U.S Air Force photo/Senior Airman Joseph A. Pagan Jr.)
