Warrant officers are single track, specialty officers with subject matter expertise in a particular area. They are initially appointed as warrant officers (in the rank of WO1) by the Secretary of the Army, but receive their commission upon promotion to chief warrant officer two (CW2).
By regulation, warrant officers are addressed as 'Mr. (last name)' or 'Ms. (last name).' However, many personnel address warrant officers as 'Chief (last name)'. Enlisted soldiers say "sir" or "ma'am" when addressing them.
