Royal Marines Police

The Royal Marines Police, or Royal Marines Police Troop (RM Police Troop) is the Royal Marines element of the Royal Navy Police and the military police arm of the Royal Marines. Members of the RM Police enforce service law and discipline.

In 2009 the RM Police came under the operational command of the Royal Navy Police for policing and investigations; providing more investigatory independence from their non-service police chains of command. although it still exists as a distinct unit under the operational control of 3 Commando Brigade.

The overall head of the Royal Navy Police (including RM Police Troop) is the Provost Marshal - Navy. As of August 2022 this was held by Commander Andy Williams, himself an ex Royal Marine Commando and ex Royal Marines Police member.

The RM Police is responsible for providing garrison policing services – law enforcement and crime prevention as well as general security advice to the command – and provide personnel to the Royal Navy Police Special Investigations Branch (RNP SIB) section for the investigation of serious crime.

RM Police personnel are recruited from within the trained strength of the Royal Marines, following completion of a first posting to a rifle troop in a Commando.

The primary formed unit of the Royal Marines Police is a troop (similar to a platoon in the Army) within 30 Commando Information Exploitation Group, the information exploitation unit of UK Commando Force, based at Stonehouse Barracks, Plymouth.

For example, in 2008 the RM Police Troop consisted of the following:

In military operations, the Royal Marines Police Troop provide military police support for all phases of operations and peacekeeping operations including co-ordinating vehicle movements out of the beachhead, marking the main supply routes and providing convoy escorts.
