hmmm lets see a re-arm pad, to load more bombs, to kill GV's.
I can think of quite a few hardcore GV heavyweights who would whine all day long if someone could keep loading bombs.
Do you really think this would not add to the frustrations of the disgruntled GV driver?
If you want air support fly it in from a different field or maybe wish for a spotter plane that doesnt have any ammo or bombs. That could be launched from a V base hangar.
