U.S. Air Force Lt. Col. Brian Vlaun, left, 28th Bomb Squadron commander, presents a certificate to a B-course graduate March 25, 2016, at Dyess Air Force Base, Texas. This ceremony was the first formal B-course graduation since the arrival of the B-1B Lancer at Dyess in 1985. The formal ceremony is now a part of the B-course curriculum and aligns the school house with similar traditions of other airframes. (U.S. Air Force photo by Airman 1st Class Austin Mayfield/Released)
