Prior to the United States entry into World War II, in November 1940, he volunteered for duty with the Royal Air Force and was commissioned a pilot officer (second lieutenant) in the RAF before transferring to the United States Army Air Forces in the grade of major, at London, England, in September 1942. His decorations include the Legion of Merit, Air Medal with six Oak Leaf Clusters and the British Distinguished Flying Cross. McColpin was credited with 12 kills, 5 probable, and 12 damaged while with the Eagle Squadrons. In both services he could have claimed a minimum of ten more Luftwaffe aircraft of mixed types destroyed on the ground by attacking German airfields in France and Germany. McColpin scored another 8 confirmed kills while in the Army Air Force.
