Green Flag Returns
Ellsworth Airmen return to Ellsworth Air Force Base, S.D., following their participation in Green Flag, an exercise designed to test their ability to survive and operate in a wartime environment, May 24, 2012. B-1 aircrews from the 37th Bomb Squadron and a myriad of support personnel participated in the exercise conducted at Nellis Air Force Base, Nev., the final scrimmage before heading downrange to Southwest Asia later this year.
