The version you have up is the one developed from the POW experience, and was not in effect until signed into law by Dwight David Eisenhower, on August 17, 1955, and I believe that was Executive Order 10631. The Code of Conduct (AR350-30) was not a part of the Uniform Military Code of Justice. It was a personal conduct mandate for members of the American armed forces throughout the world. It was reaffirmed on 8 July 1964 (DOD Directive No. 1300.7). President Jimmy Carter amended Article V of the Code on 3 November 1977.
