Pl SIB Regt), which are subdivided into Detachments, each usually commanded by a Warrant Officer Class 2. There is a section or detachment on most major British Army stations. There is also a Territorial Army section, made up of CID officers and ex-regular SIB. The Headquarters SIB Regiment is at Campion Lines at Bulford, Wiltshire. Within the RMP, SIB is known as "the Branch" or more commonly "the Feds". In 2006 the SIB was subjected to an inspection by Her Majesty's Inspectorate of Constabulary (HMIC). The Armed Forces Bill 2006 seeks to require the SIB to refer investigations into inherently serious crimes directly to the Service Prosecuting Authority (SPA) rather than to commanding officers. SIB recruit class 1 and 2 Cpl's from the General Police Duties employment group of the Royal Military Police, and each candidate undergoes 12 months Foundation Training to determine suitability.

Students who pass the entrance exam are eligible for further training on the Serious Crime Investigation Course (SCIC), a 9-week residential course held at the Defence School of Policing and Guarding, Southwick Park, Fareham. On completion, successful candidates are placed onto a merit board awaiting full-time employment as an SIB Investigator. Passing the SCIC does not automatically qualify candidates employment with the SIB, and all candidates who were successful in passing the SCIC but unsuitable for employment with the SIB will be returned to their respective unit as a Level 3 trained investigator.

In direct recognition of this, the RAF Police SIB was granted permission to use The Great Escape March as its distinct march by CAS in 2015. The Royal Air Force Police currently has one SIB Squadron based at RAF Halton with two subordinate Flights: SIB A Flt based at RAF Halton, and SIB B Flt based at RAF College Cranwell, this Squadron sits within No. 1 Specialist Police Wing.
