It is just an institutional promotion and funding fight. The air force promises more than it can deliver to get enough of an undersized pie to pay for critical upgrades. Within the army, the snakeaters cite their machismo as evidence nothing else matters. The logistics types and bottom line boys back them up because NG majors and colonels have less pentagon pull than the Domino's delivery boy. Actual combat effectiveness doesn't have anything to do with it.
The air force promises more than it can deliver
I seem to remember someone elses air force making those types of promises 64 (Dunkirk, we'll take care of the British) and 61 (Don't worry about the 6th Army in Stalingrad, We'll supply it) years ago. Lets hope we don't pull blunders of this magnitude...
