Fortunately there is an online source that talks extensively about the characteristics of Special Operations, the US equivalent of the doctrine that I've mentioned upthread.  It's very similar, as one would expect of forces that work very closely together, although the US do include in Special Operations three main areas that the UK wouldn't; CIMIC, Information Operations and CSAR.  Notwithstanding that it's a fairly useful document.

 :::::::So in the context of this  discussion (in the loosest possible sense) both documents help us understand how conventional and special forces assets relate to cone another.  In the absence of any reliable sources that support the assertion that Brigade Recce are SF, and indeed the existence of a reliable, if limited distribution, source that explicitly identifies the UK SF Group and doesn't include them, we have to rely on that understanding. 
 :::::::It may be that I've completely misunderstood the intent of WP:Verify, but it looks like the burden should be on you to demonstrate that these Brigade Recce Forces are actually SF.  From my reading of the policy, given the existence of a source that explicitly identifies the UK SF Group it would take a very strong source to contradict that MoD doctrine.  If I'm misreading that then I'd be grateful if you could illustrate how the policy should be interpreted.  So we have a source that says the following units are elements of the UK Special Forces Group - 
 :::::::22 SAS, SBS, SRR 
 :::::::18 Sigs, SFSG, JSFAW 
 :::::::63(v)Sig Sqn, SBS(R) 
 :::::::Personally I'm ambivalent about listing the reserve sub-units in this article as they tend to operate on the basis of individual augumentation anyway. 
 ::;::::So at the moment we're short of reliable sources to support the assertion that Brigade Recce Forces are SF, and from reading the doctrine it would appear that they don't really conform with the concepts of employment.  Ao how might we comply with the policy on verifiability?
