The AGC (MPGS) was formed using the model of the Vulnerable Points Wing of the Corp of Military Police.   At the onset of World War II the Corp of Military Police (CMP) fulfilled normal policing duties. As the war progressed the CMP divided into three distinct parts:

• Provost Wing - Known as 'The Red Caps'. These were employed on both general and specialist policing duties.

• Traffic Control Wing (TCW) - Formed solely to deal with the Traffic Control of formations in both frontal and rear echelon areas. TCW personnel were organised into armed companies each responsible for a specific geographical area.  Although they belonged to the CMP they carried out all instructions issued by Movement Control.

• Vulnerable Points Wing (VPW) - It was the task of the VPW to provide guards for installations and buildings that were seen as vulnerable points, such as ammunition and petrol dumps, docks, locks, bridges and power stations. They were organised into sections, each of 7 privates, under command of an NCO.  They were armed with SMGs and batons, and used guard dogs during the night.  Their primary task was anti-sabotage and this was undertaken by a mixture of static guards and patrolling.

The Cap Badge

The current MPGS cap badge incorporates the Royal Crest in gold with beneath, the scroll inscribed 'Military Provost Guard Service', all superimposed on crossed keys in silver. The design follows that of the Military Foot Police, who were raised in 1882 and disbanded in 1926, but with the addition of the crossed 19th century government keys, a traditional symbol of the custodian representing a function of the Military Provost Guard Service. The Royal Crest forms part of the badge of the Adjutant General's Corps and was worn until 1900 by the Adjutant General's Department, the Provost Marshal and Officers of the Military Police.
