ABSTRACT
In 1940, the Special Operations Executive (SOE) was formed to supplement the work of MI5 and MI6, which were geared principally to work in peace time. Subsequently, the need for special units to operate under military command, and under cover, became perceived as imperative. Originally known as L Detachment, Special Air Service Brigade and, later, simply SAS, the service was introduced on the initiative of David Stirling of the Scots Guards, and approved by the Commander-in-Chief. Members of the SAS were recruited primarily from commandos. A parallel organisation, the Special Boat Service (SBS), was established to complement the work of the SAS.
