Commander Air Force's mid-rank officers' ranks are modelled on those of the Royal Navy, the term wing commander is used as a rank, and this is the equivalent of a lieutenant colonel in the army or a commander in the navy. The rank of wing commander is above that of squadron leader and below that of group captain. In the former Royal Naval Air Service, which was merged with the Royal Flying Corps to form the Royal Air Force in 1918, the pilots held appointments as well as their normal ranks in the Royal Navy, and they wore insignia appropriate to
No. 3 (Royal Auxiliary Air Force) Police Squadron No. 3 (Royal Auxiliary Air Force) Police Squadron No 3 (Royal Auxiliary Air Force) Police Squadron formed as a consequence of the assumptions made in the Strategic Defence Review, presented to Parliament by the Secretary of State for Defence (then the Rt. Hon. George Robertson MP) in July 1998. Specifically, this recognised that deployed air operations are likely to take place at the end of a long supply chain or line of communication. Control of this line of communication ia a task which falls to the service military police organisations: The Royal Air Force Police and the Royal Military Police.
