Airmen from the 363rd Training Squadron at Sheppard Air Force Base, Texas, perform a military drill demonstration during the Nighthawks military appreciation football game at the Kay Yeager Coliseum in downtown Wichita Falls, Texas, May 20, 2017. Military drill is a historic tradition which was used to strategically move troops from one place to another while acting as a show of force. It is carried out today to honor heritage, and display the training and discipline of the U.S. Armed Forces. (U.S. Air Force photo by Staff Sgt. Kyle E. Gese)
