The corps was reformed during World War II and was granted the "Royal" prefix in 1948, adopting its current name on 4 September 1974.

[4] The Corps have also played roles in peace keeping since World War II in which they have occasionally worked with the Australian Federal Police.

[12] The Corps have held positions in traffic control and monitoring as well as a back-up communication team for the front line.

The range of skills that the Corps hold allow them to operate over a large spectrum of Australian Defence Force Units, including high-threat situations.

It then was renamed the Australian Army Provost Corps in January 1918 which was subsequently disbanded at the end of World War I.

[6] Corps personnel were spread throughout the Middle East and Europe during the war, taking part in actions at Gallipoli, on the Western Front and in the Sinai and Palestine in order to help keep troops under control and to aid with detention.

[13] The Corps in the Middle East and Greece also helped Australian soldiers in directing them to their attack lines as well as handling and guarding prisoners of war.

[6] During the war training camps for the Military Police were set up in order to increase the skill of the newly reinstated Corps.

[4][6] The Royal Australian Corps of Military Police also provided aid in 2006 East Timorese crisis when the country experienced civil upset.

[6] The Royal Australian Corps of Military Police were provided with the Governor General’s banner on April 7, 2001 at the Lamia Barracks in Holsworthy.

The Corps before 1949 were recognised only by their red MP (Military Police) armband which they still wear today as they only received an official badge in 1949.

One of the RACMP’s more distinguishing items of clothing is their scarlet beret, it has been the official headdress for the authorised members of the Corps since March 1975.

[9] The Military Police must wear a white belt with equipment attached in addition to their scarlet MP identification badges.

[8] The holster pistol, hand cuff pouch and tactical baton holders and items are only worn when the Corps have been ordered to do so.

[8] The Royal Australian Corps of Military Police are involved in many smaller or separate units throughout the defence force.

[5][11] These personnel are required to train and handle dogs used for a wide range of Military Police roles such as tracking, crowd control and apprehension of criminals.

[7] The unit had been put together out of necessity during the first world war and therefore members were not provided with the high amount of training they’re now receiving over 100 years since their original formation.
