《三略·上略》
因此，将帅要令出必行，赏罚必信，像天地时令那样不可更易，这样，将帅才能统御士卒。士卒服从命令，才可以出境作战。
故将无还令，赏罚必信；如天如地，乃可御人；士卒用命，乃可越境。
Thus, a general's orders must be obeyed without question, and rewards and punishments must be consistent, like the seasons of the heavens and the earth. In this way, they can command their soldiers. Soldiers obey orders so that they can go into battle and fight.
