I was witness to some brilliant SF guys during OIF I, who basically collected up a bunch of underused NG assets and used them as "force multipliers". They had to train them a bit, but I think they got good use from them.

On CSS; in my experience, as a Combat Arms guy who spent a year in the desert with them, they don't HAVE a "brightest and best". The CSS officer development in the US Army is so broken that even the "best" were bloody awful.

I think a tour with SF would help fix that "broken-ness".
