The period of 300+ saves a deployment has passed for the HH-60 dudes, unless we kick off another 100k+ troop conflict. I can't give you tons of specific info, as I'm a Huey guy and usually get 2nd hand info on CSAR stuff.
Hueys are fun, but have trouble really doing the mission set well... need a bigger helo for some of the stuff people want. The MH-139 (Huey replacement) contract was awarded and not protested, so that should be coming online in the next decade or so. Global Strike is really pushing more offensive capabilities than were traditionally done in the missile complexes. There is a lot of potential in that, but also some thrash in tactics and training. So, some crews are TDY quite often.
