Having read Sun Tzu, I'd say he'd actually be a cleric. The first line of the Art of War is actually an admonishment telling states not to go to war lightly. Funnily enough, for such a great general, Sun Tzu actually counseled that war should only be used as a last resort, which makes him all the more greater in my eyes.
Maybe it should be - It is a sound maxim that when an act is stupid, the dice may excuse it, and when the dice is a natural 20, always excuses it.
