Ministry of Defence Guard Service
The Ministry of Defence Guard Service (MGS) is part of the Ministry of Defence Police and Guarding Agency, and provides British Ministry of Defence (MOD) establishments with unarmed security guard and patrol services.
The Guard Service deals with access and pass control, key control, vehicle and personnel searching, security patrols of buildings and perimeter fences, dog patrols, CCTV, and alarm monitoring. It also performs other duties like helicopter marshalling, first aid provision, mail and baggage scanning, security sweeps, and health and safety guidance.
MGS frequently shares facilities and works with the Ministry of Defence Police, with whom they have a similar relationship as Police Community Support Officers do to territorial police forces; although MGS officers are unarmed civilian civil servants without any police powers.
MGS can also work with Royal Military Police (RMP)[citation needed] and the Royal Air Force Police (RAFP) on security duties.
