They are initially appointed as warrant officers (in the rank of WO1) by the [[United States Secretary of the Army|secretary of the Army]], but receive their [[Officer (armed forces)#Warrant officers|commission]] upon promotion to chief warrant officer two (CW2).

By regulation, warrant officers are addressed as "Mr. (last name)" or "Ms. (last name)" by senior officers and as "sir" or "ma'am" by all enlisted personnel.<ref name=ar600/> However, many personnel address warrant officers as "Chief (last name)" within their units regardless of rank.
