The British Army contributes two of the three special forces formations to the United Kingdom Special Forces directorate: the Special Air Service and Special Reconnaissance Regiments. The Special Air Service consists of one regular-army and two reserve regiments. The regular regiment, 22 SAS, has its headquarters and depot in Hereford and consists of five squadrons (A, B, D, G and Reserve) and a training wing. 22 SAS is supported by two reserve regiments: 21 SAS and 23 SAS—collectively, the Special Air Service (Reserve) (SAS [R])—under the command of the 1st Intelligence, Surveillance and Reconnaissance Brigade. The Special Reconnaissance Regiment (SRR), formed in 2005, performs close reconnaissance and special surveillance tasks. The Special Forces Support Group, under the operational control of the Director of Special Forces, provides operational manoeuvring support to the United Kingdom Special Forces.
