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.

Personnel are eligible to undertake the close protection courses run by the Royal Military Police.

RM Police Troop, in the UK, do not generally carry TASER, incapacitant spray, or firearms.

The Royal Navy Police now have their personnel wearing body warn video cameras (BWVC).
