However, I, and I suspect most infantry troops, would prefer that cavalry to be in the form of a (relatively) fast air asset like Harrier, on scene in 15 minutes pretty much anywhere in the AOR, than the undoubtedly capable Apache an hour or two later.
Probably true to a point, but what happens when the clag is down to 100' or the CAS cannot find the tgt and doesn't have the time to loiter, the mountains up there can be pretty awkward to move around at 300+ kts too.
Bear in mind the AH will be on some form of strip alert fairly close to the Hot spots.
