President Harry S Truman had served in the National Guard, with Army artillery in World War I, and as a colonel in the reserve after the war. As a senator in World War II, he had been struck in the Pearl Harbor hearings by the inadequacies of the military system, and he had chaired a special Senate committee probing into the duplications, inefficiencies, and waste in the separate Army and Navy operations and contracts. General of the Army George C. Marshall, who had Truman’s admiration, had called for military unification during the war.
