SERE training
Students in the Survival, Evasion, Resistance and Escape School, learn about different ways to communicate with aircraft at the Air Force Survival School Training Area in Cusick, Washington, Feb. 18, 2018. Before students go into the field for training, they have to pack a bag with specific gear to include a global positioning system, compass, map, shelter materials and rain poncho. They also pack equipment and tools used to signal for rescue. (U.S. Air Force photo/Senior Airman Sean Campbell)
