Extracted from the Wikipedia article Officer (armed forces).
Types of officers
Commissioned officers exist in all eight uniformed services of the United States. All six armed forces of the United States have both commissioned officer and non-commissioned officer (NCO) ranks, and all of them (except the United States Space Force) have warrant-officer ranks. The two noncombatant uniformed services, the United States Public Health Service Commissioned Corps and the National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps), have only commissioned officers, with no warrant-officer or enlisted personnel.
