More precisely get rid of the VH and build a motor pool the size of 4 to 6 bomber hangers, filled with GV's an open area,, much like you would find in the real world,, a storage area for GV's,, with a VH for repairs,, to shut down GV's,, you would have to bomb the whole thing down,, maybe requiring 10 thousand pounds or more to destroy,, and it must be spread out over the whole area,,,,, a secondary idea for that would be specific areas for specific GV's,,, kill the tank area no tanks!!! kill the light GV area,, no M-3's no M-8's,, no M-18's ( please don't) just a thought!!!!
