Survival, Evasion, Resistance, and Escape (SERE) is a program, best known by its military acronym, that provides U.S. military personnel, U.S. Department of Defense civilians and private military contractors with training in evading capture, survival skills and the military code of conduct. Established by the United States Air Force at the end of the Korean War (1950–53), it was extended during the Vietnam War (1959–1975) to the U.S. Army, U.S. Navy and U.S. Marine Corps.
