In one of the LIC books commissioned by the USAF in the late 80s early 90s I read recently it said something to the effect "It is as imperative to mission success that the Air Force have infantry as the Army have Air Power" I about fell out of my chair.

C4ISR Journal this month has some pretty good articles on detecting stealthy air craft using ultra-violet and other out of visible spectrum light techniques. Cheap, inexpensive, useable for targeting (as anybody who knows anything about missiles will tell you), light is a big handicap for stealth. High power lasers of course are the answer for AAA and SAMs. But, then who needs stealth. Somebody smarter than me likely has figured that out.
