You address him as "Sir" and brace up to the position of attention however you do not salute.
AnswerIt depends who you are. If you hold a lower rank, then you call him 'Sir'. If you are of higher rank, then you call him 'Mr Smith' or whatever his name is!
By Army Regulation 600-20 the proper way to address a warrant officer regardless of rank of the person addressing him or her is Mister (Mrs./Miss/Ms.).
Warrant Officers are not responsible for troops or personnel. But, in referring to a Warrant Officer, face to face you would address him as "Sir" as any other officer. If you work with him or are more familiar, he may permit you to refer to him as "Chief." If referring to a Warrant Officer in a conversation with a third party, you would refer to him as "Warrant Officer __________."
The proper way address them is Mr. or Mrs Last Name
