Hence the experienced soldier, once in motion, is never bewildered; once he has broken camp, he is never at a loss.

When torrential water tosses boulders, it is because of its momentum. When the strike of a hawk breaks the body of its prey, it is because of timing.

And regulation entails organizational effectiveness, a chain of command, and a structure for logistical support.

Therefore the good fighter will be terrible in his onset, and prompt in his decision.
