The Royal Military Police (RMP) is the corps of the British Army responsible for the policing of army 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 and scarlet coloured berets. The RMP's 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, which was followed by the Military Foot Police in 1885. Although technically two independent corps, they 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 on 28 November 1946. In 1992, the RMP amalgamated into the Adjutant General's Corps (AGC), where they form part of the AGC's Provost Branch. Non-commissioned members of the RMP receive their basic training as soldiers at the Army Training Centre in Pirbright. They then receive further training at the Defence School of Policing and Guarding (DSPG), previously known as the Defence College of Policing and Guarding (DCPG). 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". History The Provost Marshal is a post which goes back to the 13th century and was originally an under-officer of the Earl Marshal. In 1685 the role of Provost Marshal General became a permanent post. The Cavalry Staff Corps of 1813–14 and 1815–18 is regarded as Britain's first standing military police force and a forerunner of the Royal Military Police. The Military Mounted Police was formed in 1877 and the Military Foot Police was formed in 1885. During the First World War the Military Police grew from 508 all ranks to over 25,000 all ranks by the end of the War. During the Battle of Neuve Chapelle in March 1915 the Military Police served the Army as a whole, rather than individual units. On 27 February 1926 the Corps of Military Police was formed by merging the Military Mounted Police and the Military Foot Police.
