Staff Sgt. Jesse Koritar, 90th Ground Combat Training Squadron training instructor, signals for his men to rappel out of an Army UH-60 Black Hawk at F.E. Warren Air Force Base, Wyo., May 2, 2019. During flight, the noise from wind and rotors is too loud to communicate verbally requiring the use of hand signals to accurately transfer information. (U.S. Air Force photo by Staff Sgt. Ashley N.
