The original United States Armed Forces no longer exists: the explanation in "Origins" was that Chief Judge Goodman had built up the Judges until they were a match for the United States Army, as a precaution against President Booth. When Booth was overthrown after the Atomic Wars, the remains of the US Army were routed and finally destroyed in 2071's Battle of Armageddon. (In the immediate aftermath of the war, military discipline broke down and the Judges had to kill or arrest soldiers that were preying on the citizens.)
