Quote (http://www.eliteukforces.info/18-UKSF-Signals/264-sas-squadron/) "The men of 264 (SAS) Signals are part of the Royal Corps of Signals and have not gone through SAS selection, although they do have to pass the Special Forces Communicator (SFC) selection course. 264 Signals are now under the umbrella of 18 UKSF Signals Regiment." But- this is what they have to pass.... Quote (http://www.eliteukforces.info/special-air-service/sas-reserves/#selection) "SAS (R) Selection Selection is open to men over 18 and under 32 (or under 35 for those with military experience) who are fit and do not have a criminal record. Selection itself consists of a series of physical tests run over a series of weeknights and weekends, in keeping with the part-time nature of TA units. Selection consists of the following phases: 1. APTITUDE Physical and mental stamina, along with navigational ability are stretched to the limit over series of tests. The aptitude phase culminates with a 64 kilometer march, with a 60lbs bergen, over the Brecon Beacons in Wales. Aptitude consists of: 9 x weekends of endurance training. 1 x week endurance training in the Brecon Beacons. 1 x week assessment (Test Week) in the Beacons. 2. STANDARD OPERATIONAL PROCEDURE (SOP) TRAINING Instruction in UKSF SOP'S and tactics comprises of: 9 x weekends patrol SOP's including surveillance and reconnaissance. 1 x week live firing including patrol contact drills and Tp offensive action. 1 x 9 day battle camp comprising: Live firing assessment. Field training exercise to test the skills learned throughout Selection. This culminates in Conduct after Capture (CAC). On successful completion of this training, ranks are badged as SAS(R) and are assigned to their respective units for continuation training. SAS(R) CONTINUATION TRAINING Candidates who successfully complete Selection will enter a period of probation and must complete the following courses to be fit for mobilisation.

Once successfully through continuation training, SAS(R) soldiers will undergo periodic UKSF Military Annual training Tests (MATTs) and Main Training Periods. Additional qualifications can be sought throughout the SAS(R) soldier's career: Patrol Medics Enhanced Surveillance and Reconnaissance Languages Emergency Close Air Support Support Weapons Close Protection" So surely they are SAS because they've done nearly the same as 21 and 23?? Would one have a right in either of the two to feel they are in the SAS?
