I agree completely with Ken. (Though he may object to my comments.) As long as we have air and firepower superiority our enemies are going to prefer to fight danger close. A soldier who can fight and win danger close, will be able to call in CAS and probably will enjoy doing so.

(Undoubtedly it is a good idea to maintain a strong AA capability just in case the Air Force makes promises it can't keep. If we ever reduce AA capability so that we can afford to build schools in Iraq, then we've gone too far.)
