He was Assistant Director of Operations for the 821st Air Division at Ellsworth Air Force Base, during the Cuban Missile Crisis.

Evans was awarded the Air Medal by Headquarters of Twelfth Air Force while serving as a First Lieutenant in the 321st Bombardment Group (Medium). The citation reads:

For meritorious achievement while participating in aerial flight as bombardier of a B-25 type aircraft. On 30 January 1944, Lieutenant Evans flew as lead bombardier of a thirty-three plane formation attacking a road junction at Genzano, near Anzio beach, Italy. Despite intense anti-aircraft fire which heavily damaged his airplane upon the approach to the target, Lieutenant Evans, displaying outstanding courage and professional skill, directed his pilot on a perfect run over the objective, thereby enabling the formation to release its bombs with devastating effect upon this vital link in enemy communication lines. His proficiency in combat reflects great credit upon himself and the armed forces of the United States.

Evans was later awarded the Distinguished Flying Cross for his attack upon a railroad bridge near Attigliano, Italy on April 17, 1944.^[2]

He was decorated for actions during the Battle of Anzio in early 1944, and received the U.S. Distinguished Flying Cross and Air Medal.^[1] After the war he served as bombardier on B-36 aircraft and radar navigator on B-52 aircraft in the Strategic Air Command in addition to being the winner of the 1955 SAC bombing competition and later Base commander, Walker Air Force Base, Roswell, New Mexico.^[3]
