Hello Laura, Can I just say a few words regarding the subject. During my service with the Royal Marines all personnel involved with the 'Policing' of a Royal Marine Barracks, Depot etc were termed as 'PROVOST STAFF'. I never heard them referred to as Royal Marine Policeman. Whilst serving on a Royal Naval Ship the 'REGULATING BRANCH' would administer discipline of the Naval Ratings. and The Officer Commanding Royal Marines would administer his own men, A lot of R.N. shore establishment had 'Dockyard Policemen', and these were usually Naval Hospitals and perhaps other establishments that did not warrant Regulating or Provost staff.Perhaps if you Googled' 'Provost' something might turn up. Best of luck. Don FRASER
