RAF Police Flights are responsible to and directed by a RAFP Squadron. Squadron HQs are based at the larger RAF stations and provide remote oversight of the Police Flights at the units within their respective area of responsibility. Squadron HQs are themselves responsible to, and directed by, the Deputy Provost Marshal of the RAFP, who is a Wing Commander. RAFP personnel are not responsible to, or under the direct command of, the Commanding Officer (Station Commander) of the station at which they are situated; all service police on RAFP Wings remain under the command of the Provost Marshal (RAF). Their authority to act as service police stems directly from the Armed Forces Act 2006. Service police are able to issue lawful commands to any service person, regardless of their rank or trade. The RAF Police also provides the RAF's Counter-intelligence & Protective Security (CI)&(PS) role, similar to that carried out by the Intelligence Corps and elements of the Royal Signals of the British Army. IT Security (ITSy) is a further specialisation within the protective security field and personnel trained to this level are expected to perform all PS and ITSy related tasks.
