To combine super-efficiency with incompetence is a scary notion indeed. I believe some of the British commanders managed to do so in both the French & Indian War and the American Revolution. One of them was named Braddock, and he lost a whole army doing it, when he was attacked by a large force of Indians in the deep forest.

My computer also tends to do it when playing wargames against me, committing certain errors in strategy that must be seen to be believed, while it totals up every last jot and tittle with superb accuracy.
