To answer that question, you would have to ask the Taliban. I suggest if you want to canvass opinion in Sangin, you'll have to do it when there isn't an Apache overhead. They seem to want to get under cover when they are there.
You could ask the West Side Boys, even in their drug fuelled minds, they feared the Harrier above all else.
You could as the Somali Warlords, they may have knocked a couple of Blackhawks out of the low hover, but I don't think they were very keen on the AC130...at all!
You could ask the VC what they thought of the Huey Gunships, or the USAF/USN napalm drops.
Just a few thoughts....
