For what it's worth, SBT-12 (sort of "special forces" at least) wasn't too picky about what helo squadron was used. In CONUS we did a lot of cast and recovery, roping onto boats, and much more I would classify as "just fun" stuff with the whatever Navy helos were available at North Island. While deployed, it was pretty much whatever air assets the JTF or exercise commander could grab (usually Army, Marine, or the AF rescue squadron 60's) to help out. Again, I don't think the SBT's are anywhere near the level of a SEAL platoon, but it seemed like while we were deployed, the other services were able to support NSW just fine. It seemed to me our sister SEAL platoon worked pretty much the same way.
