Not all of the uniformed services use all of the grades; for example, the Coast Guard has authority to use, but does not use the grades of W-1 and W-5, the United States Navy formerly did not use the grade of W-1 and the United States Air Force discontinued appointing new warrant officers in 1959 (although the last USAF warrant officer did not retire until 1992).
