UK Joint Special Forces Selection is the selection and training process for candidates of the United Kingdom Special Forces: Special Air Service, Special Boat Service, and Special Reconnaissance Regiment. Members of the SAS and SBS undergo selection up to the award of a sand-coloured beret to SAS personnel, whereupon SBS candidates undergo further selection to qualify as Swimmer Canoeists, and SAS personnel undergo further specialist training. SRR candidates undergo the Aptitude Phase, before going on to their own specialist covert surveillance & reconnaissance training.
Until the late 1990s, candidates for the SAS and SBS underwent selection separately.
Selection is held twice per year, in the summer and in the winter. Typically, less than 10% of candidates make it through the selection process.[1]
