SASless
Worth bearing in mind that 2 Sqns of SAS had to do an advance to contact during one phase of their time in Afghanistan, a total misuse of their skills, and one good reason for the formation of the ranger/1Para bttn.
Jess - when you consider that WW2 was the first time SF were used in any recognisable sense, and the scale of the war as a whole, it's more surprising there were not more SF, in fact. The fact that all SF units were disbanded at the end is not that surprising in hindsight, but lessons had to be re-learned by Hereford in GW1 that had clear parallels with the earliest days of the SAS and LRDG in the Western Desert in 42/43.
Also remember that a good 50% of ORs only do one tour in Hereford and then return to their units - taking skills back to (mostly) line infantry regts.
