The precedence of the commissioned officers and other officers of the Army, Navy and Marine Corps is determined first by the grade or rank which the officers hold by virtue of their commissions or appointments, and if of the same grade or rank, then by the date of commission or appointment in the grade. There are certain exceptions to this latter rule in the case of some grades in the Staff Corps of the Navy. The precedence of the warrant officers, noncommissioned officers and petty officers of all the services is determined upon the same principle, the seniority of the different grades and the relative seniority of the grades in different services being determined by regulations and orders, and the precedence in each grade being determined by the dates of the warrants or appointments. The accompanying table shows the rank and title of each grade in the Army, Navy, Marine Corps and Coast Guard, all of the grades having the same relative rank being on the same horizontal line.
