Note that the US military usually uses O-1 to O-11 to symbolize officer, and not the NATO codes of OF-1 to OF-10 in which all subaltern officers are classed as OF-1 (O-1 and O-2 in US). Not listed are US warrant officers. In accordance with Army Regulation (AR) 135-100 , Department of the Army Pamphlet (DA Pam) 600-11 and Army Field Manual (FM) 22-100 (para A-3) [1], a warrant officer is an officer who can and does command, carry out military justice actions and sits both selection and promotion boards. A warrant officer is a single-track specialty officer, initially appointed by the Secretary of the Army, he/she receives a commission upon promotion to Chief Warrant Officer Two (CW2).
