Note: Since the Fleet is the senior service, Fleet officers will be accorded first rank over other officers at the same rank. In other words, the most junior Naval Captain is senior to every Marine Corps Captain, and the most junior Marine Corps Captain is senior to every Air Corps Captain. Within a service branch, date of commission or promotion determines who is senior and commanding.
