Cap Badge - The Military Provost Staff Corps Badge: The Royal Cypher surmounted by the King's Crown in Brass. The official task of the Corps is to make good soldiers out of bad. When the badge was issued with the Queens Crown and the New Royal Cypher a title scroll was added below. Today they staff, under the Provost Marshall, the military prison in Colchester and retrain soldiers during their sentence prior to returning to their units. The MPS does not recruit directly from civilian life, but only accepts applications from soldiers already serving in the Army. All its members hold a minimum rank of Corporal. The Military Provost Staff (MPS) is administratively part of the Adjutant General's Corps. It also provides operational support and technical advice for Prisoner of War handling during conflicts and monitors PoWs in custody. It is based at the Military Corrective Training Centre (MCTC) in Colchester, Essex. The Military Prison Staff Corps was formed in 1901 under Army Order 241. It was redesignated the Military Provost Staff Corps in 1906. As the Military Provost Staff it became part of the Adjutant General's Corps (AGC) on 6 April 1992, forming the Provost Branch along with the Royal Military Police. It retains a separate identity within the AGC, however, keeping its cap badge and other symbols.
