Johnny Cash may have been known as “The Man In Black” and fostered an outlaw image by performing (and recording) at U.S. prisons, but the influential singer was also a military man and enlisted in the US Air Force on July 7, 1950. Cash was also a bit of a hero since he was the very first morse code operator to pick up the news of the death of U.S. enemy Joseph Stalin. Cash was honorably discharged as a Staff Sergeant on July 3, 1954.
