Survival, Evasion, Resistance, and Escape (SERE) is a training concept originally developed by the United States during World War II. It is best known by its military acronym and prepares a range of Western forces to survive when evading or being captured. Initially focused on survival skills and evading capture, the curriculum was designed to equip military personnel, particularly pilots, with the necessary skills to survive in hostile environments. The program emphasised the importance of adhering to the military code of conduct and developing techniques for escape from captivity. Following the foundation laid by the British, the U.S. Air Force formally established its own SERE program at the end of World War II and the start of the Cold War. This program was extended to include the Navy and United States Marine Corps and was consolidated within the Air Force during the Korean War (1950–1953) with a greater focus on "resistance training."
