A provost sergeant is a non-commissioned officer associated with military police.
A provost sergeant wears no distinctive trade badge.
They can, however, be identified by the brassard they wear on their uniform, which carries the letters "PS"[citation needed] or "RP" as well as sergeant's stripes.
In the United States Army Military Police Corps or United States Marine Corps Military Police,[citation needed] the title of provost sergeant typically refers to the operations sergeant in charge of the staff of the Provost Marshal office or the NCO in charge of an MP station.
U.S. Army provost sergeants cannot be recognized by any specific insignia, and few provost sergeants even wear the distinctive military police identification patch on their Army Combat Uniform.
