I'm pretty sure that everything I mentioned is valid, even though I cannot provide references for everything.

Regarding Raiden: Yes I know that he was part of Force XXI, but in the MGS1-briefing, Campbell says that the Next Generation Special Forces were created by combining Force XXI with anti-terrorist units specialised in dealing with ABC-weapons. So I always assumed that Raiden was also a member of the NGSF.
