The Roman legions were not the ancient world's only professional military force. The Seleucids and other peoples possessed broadly similar arrangements. In this comparison, Roman distinctiveness lies less in inventing every institution than in applying such systems effectively and borrowing useful practices. The point reframes Roman military success as adaptation and execution rather than institutional uniqueness.
