Mig Alley is set in the Korean War and spans the timeline from June 1950 to July 1953. Historically this was a very brutal and important war. It came at a time when all the major players were still recovering from WWII. It was a big show down that pitted the United Nations against the Communist North Koreans and later Red China, intermixed with that was Russian aid in equipment and ... manpower. Much of the tactics still originated from WWII. The biggest difference came from the use of jets in the air war.
