U.S. Air Force Maj. Gen. Bill Hyatt, U.S. Air Force Warfare Center commander, recognizes the contributions of the men and women of the 98th Range Wing during a ceremony re-designating the unit The Nevada Test and Training Range at Nellis Air Force Base, Nev., June 21, 2011. Col. Kenneth Thompson, former defense and air attaché to the U.S. Embassy in Cairo, assumed command of the NTTR during the event. Like the 98 RANW, The NTTR will remain a direct reporting unit to the U.S. Air Force Warfare Center and continue to operate, maintain and manage the 2.9-million-acre range (42 percent of the land managed by the U.S. Air Force) and 12,000 square miles of military airspace. More than 1,000 military, civilian and contract personnel are assigned to the organization. (U.S. Air Force photo by Senior Airman Brett Clashman/Released)
