give up the air force?
Speaking as a current member of USAF and as an Aircraft Maintainer here. While I dislike flight crew and their ilk, that's mainly for personal reasons. However, to say that the USAF is a worthless and useless service is just asinine. The Navy and the Army does not do what we do, nor could it without a large overhaul.
We're more then just glorified taxis. We're responsible for a VERY large precentage of the destruction of enemy forces. This is due to bombing and strategic strikes with fighters and close air support. When the marines hit Falujah, they damn sure didn't call for Navy. They called for the AC-130 gunships from Air Force Spec Ops Command.
The Air Force is far from worthless and useless. Simply because we're smart enough to avoid having to go into close combat where we lose four or five thousand of our troops doesn't mean we're useless. It just means we utilize a different set of capabilities to solve our problems then just sending wave after wave of bodies at it till it gets solved.
