If only to annoy SASLess...
All airmen should know of the American John Boyd's 'OODA Loop' that was originally used for air-to-air combat but is now used for combat as a whole. It was originally meant to stand for Observe, Orientate, Decide, Act - if you could do this quicker than your opponent then you 'should' win.
Well it would appear that out American cousins have now decided to take this one step further and altered the tried and tested formula to:
Observe
Over-react
Destroy
Apologise
OK I admit, I stole this joke from someone else (a USAF B1 pilot).
