The Royal Military Police (RMP) is the corps of the British Army responsible for the policing of service personnel, and for providing a military police presence both in the UK and while service personnel are deployed overseas on operations and exercises. Members of the RMP are often known as 'Redcaps' because of the scarlet covers on their peaked caps, or scarlet coloured berets.
The RMP origins can be traced back to the 13th Century but it was not until 1877 that a regular corps of military police was formed, with the creation of the Military Mounted Police (MMP). This was followed by the Military Foot Police (MFP) in 1885. The Military Mounted Police first engaged in combat in 1882 at the Battle of Tel el-Kebir. Although technically two independent corps, the two effectively functioned as a single organisation. In 1926, they were fully amalgamated to form the Corps of Military Police (CMP).
In recognition of their service in the Second World War, they became the Corps of Royal Military Police (RMP) on 28 November 1946. Non-commissioned members of the RMP receive their basic training as soldiers, at the Army Training Regiment in Winchester. They then receive further training at the Defence College of Policing and Guarding.
RMP commissioned officers are trained at the Royal Military Academy Sandhurst, as are all other British Army officers. The regimental march of the RMP is "The Watchtower" or "Hoch Heidecksburg" originally a German Army marching tune from 1912 by Rudolf Herzer. The RMP motto is Exemplo Ducemus, Latin for "By example, shall we lead".
During the Second World War the Military Police grew from 4,121 all ranks to over 50,000 all ranks within six major branches of specialists:[1]
Provost Wing - Responsible for general policing. Provost Companies were included in the order of battle of Home Commands, Armoured, Infantry and Airborne Divisions, as well as at Army and Corps level and with independent Brigades. From 1942, "Ports Provost" Companies were raised, consisting of a mix of Provost and Vulnerable Points Sections, which were deployed on security and policing duties within ports and docks.
Field Security Wing - First formed in 1937, personnel of the F.S.W. wore lincoln green cap covers and brass shoulder titles on their tunics with the letters "FSP", to distinguish them from the rest of the Corps. They wore the standard CMP cap badge, but unofficially ground down the wording "MILITARY POLICE" from the lower scroll of the badge. In July 1940 the Wing was absorbed into the new Intelligence Corps.
Vulnerable Points Wing - Formed in 1940 to provide security of static locations and establishments. They were known as "blue caps" from the oxford blue cloth covers worn on their service dress caps. Originally intended to act as static Companies and detachments, VP Coys were later deployed in North West Europe, guarding prisoner of war camps and other static installations. The VP Wing was quickly phased out at the end of the war, but re-appeared briefly in the Supplementary Reserve/Army Emergency Reserve between 1950 and 1961.
Special Investigation Branch - The S.I.B. was first formed in 1940, with 19 detectives from the Metropolitan Police transferred to the Army for deployment in France. From this small beginning the Branch expanded into numerous Sections which were deployed both in the U.K. and overseas, providing the Corps with its own criminal investigation Department to conduct more detailed and protracted investigations into organised crime and serious offences such as murder.
Traffic Control Wing - Formed in 1941, TC Coys were deployed throughout the United Kingdom, releasing Provost Companies from the tasks of traffic control. TC Coys were later deployed in the Middle East, Italy and North-West Europe. The Wing was phased out of the Corps by 1946.(Many sources over the years continue to erroneously state that personnel of the Traffic Control Wing wore white cloth cap covers. This is not the case. CMP (TC) personnel did not wear cap covers when on duty, unless they had undergone a basic course in police duties, in which case they were authorised to wear red top covers as per the Provost Wing).
Some 950 Warrant Officers, Non-Commissioned Officers and Other Ranks of the Corps of Military Police were killed in action or died in service; a high proportion of the latter in traffic accidents and several were murdered whilst carrying out their duties. In addition, 28 Officers were killed or died whilst serving with CMP units.
