Graf AAF can take C-130's. Ingolstadt-Manching might be available if the Germans agree to it. Ramstein is a long road march from Rose Barracks.
I think they will fix the runway at Graf to take C-17's and garrison much of the SBCT at Vilseck.
The study pointed out the fallacy of pumping megabucks of tax-payer's money into upgrading mega-APODs like McChord and Charleston to improve deployment times while ignoring the enroute infrastructure constraints. It's like hooking up a 10 gal/minute pipe to a 5 gal/min pipe and expecting to put out 10 gallons of water every minute minute.
(The political downside was that it meant putting dollars into overseas projects instead of congresscritters' local districts. As a result, the money went into improving airfields here in the U.S. as pork barrel projects.)
