DeBerry's Falcons dominated the Commander-in-Chief's Trophy series contested yearly with arch rival military academies Army and Navy. Air Force won the trophy 14 times and shared it once in DeBerry's 21 seasons. However, DeBerry lost the AF-Navy game and, subsequently, the CIC trophy each of his last four years at Air Force. He was a combined 34–8 against the Black Knights and Midshipmen and is the most successful coach in service academy history. DeBerry led the Academy to 12 bowl games, in which he had a 6–6 record.
