MPGS meaning in Governmental ?

The Military Provost Guard Service (MPGS) is responsible for maintaining physical security at British Armed Forces locations throughout Great Britain. It is one of three constituent units of the Adjutant General's Corps Provost Branch (the other two parts being the Royal Military Police and the Military Provost Staff). The Provost branch is the responsibility of the Provost Marshal who is a Brigadier from the Royal Military Police. In Northern Ireland, security at Ministry of Defence establishments is provided by the Northern Ireland Security Guard Service (Civil Service) and the Northern Ireland Guard Force (Army) in a similar manner to that of the MPGS in Great Britain.

The aim of the MPGS is to rationalise guarding arrangements at sites where service personnel normally live and work. The MPGS replaces previously civilian-held duties with armed soldiers. The MPGS works alongside the civilian unarmed Ministry of Defence Guard Service (MGS (Civil Service)).
