A provost marshal is a title given to a person in charge of a group of military police (MP). The title originated with an older term for military police, provosts. While a provost marshal is now usually a senior commissioned officer, he/she may be a person of any rank, who commands any number of MPs; historically, the title was sometimes applied to civilian officials, especially under conditions of martial law, or when a military force had day-to-day responsibility for some or all aspects of civilian law enforcement (such as some British colonies). A provost marshal may also oversee security services, imprisonment, fire/emergency services and ambulances.
British Armed ForcesEdit
In the British Armed Forces, the provost marshal is the head of the military police of each service, with the senior military police officers at lower levels being titled deputy or assistant provost marshals. In many cases the provost marshal is in charge of discipline. By the end of the 17th Century each regiment had its own provost marshal under the Provost Marshal General. Currently, the Provost Marshal (Army) is also the commander of the 1st Military Police Brigade.
The Canadian Forces Provost Marshal (CFPM) is the branch advisor for the Canadian Forces Military Police Branch, and also the Commander of the Canadian Forces Military Police Group (CF MP Gp). The CFPM is headquartered in Ottawa and has five sections, each under the command of a deputy provost marshal (DPM): DPM Police, DPM Resource Management, DPM Individual Training and Education, DPM Security, and DPM Professional Standards.
The CF MP Gp is composed of the Canadian Forces National Investigation Service (CFNIS), Military Police Security Services (MPSS), Canadian Forces Service Prison and Detention Barracks (CFSPDB), and Canadian Forces Military Police Academy (CFMPA).
German Armed ForcesEdit
The chief of the German Military Police (Feldjäger) is called General der Feldjägertruppe (equivalent to provost marshal general). The German Armed Forces (Bundeswehr) do not have a specific title for military police officers so in most tactical units and especially in multinational deployments, they will use the English term provost marshal.
United States Armed ForcesEdit
In the United States Army and United States Marine Corps, the senior-most military law enforcement officer is the Provost Marshal General (PMG) (Army) or provost marshal (USMC). The US Army PMG is a post that was reinstated in 2003, having been abolished 29 years earlier. The PMG is a general in charge of the United States Army Military Police Corps, U.S. Army Criminal Investigation Command (CID) and United States Army Corrections Command (ACC) policy and procedures from the Office of the Provost Marshal General (OPMG) at The Pentagon.
The senior MP officer at the theater, corps, division, and brigade level and for each garrison is known as a provost marshal. In many US Army garrisons, a provost marshal is at times also responsible for the provision of fire and physical security as well as law enforcement services and thus is also referred to as the director of emergency services (DES).
The British far-right group Britain First also use the rank, presumably as head of their paramilitary wing 'Britain First Defence Force', with provision for two "provosts marshal" in their official group constitution.
