SERE is a United States military acronym for Survival, Evasion, Resistance, and Escape, a program that provides military personnel, 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 (1959-75) to the Army, Navy and Marines. Most higher level SERE students are all military aircrew and special operations personnel considered to be at high risk of capture.
