Since the Code was proclaimed in 1955, each of the Services has improved its instruction on how to avoid capture and what to do if taken prisoner of war. Each Service program has been analyzed, and the best points are reflected in this revised pamphlet, "The U.S. Fighting Man's Code." Some of the material in the booklet has been drawn from Army Pamphlet No. 30-101, "Communist Interrogation, Indoctrination, and Exploitation of Prisoners of 'Val'"; The Airman, official journal of the Air Force; and the Naval Training Bulletin. Materials and suggestions have been received also from the U.S. Marine Corps, and these are reflected in this pamphlet." See also the Army training film
