text: The Royal Air Force is policed by the Royal Air Force Police (RAFP).
  The Royal Navy is policed by the Royal Navy Police (formerly the Royal Navy Regulating Branch). The Royal Marines maintains a platoon-sized Police Troop, formerly the Royal Marines Police, which has been part of the Royal Navy Police since 2009.
  Each of the three Services has its own Special Investigation Branch (SIB) to undertake investigations of a serious or complex nature. SIB investigators normally wear plain-clothes and operate in a similar to manner to civilian police CID.
  All British military police are correctly named as 'Service Police' and conform to the Service Police Codes of Practice (SPCoP). Powers for all arms of the British Service Police come from Armed Forces Act 2006, which came into force in 2008.
  The Military Corrective Training Centre—for all three services—at Colchester is operated by the Military Provost Staff Corps (MPS), an all-senior NCO corps which recruits only from serving personnel (but will liaise with other military and government sources where appropriate). MPS are not police and serve the same function as a prison officer. This role is additionally carried out by them on operations when handling foreign detainees at a main operating base such as Camp Bastion/Kandahar.
