《六韬·犬韬·教战》
这是为了使全军的行动整齐划一。将帅必须先明确地告知士兵应该怎样操练，并且反复申明讲解清楚，然后教习操练战斗动作以及根据旗帜指挥信号的变化而采用相应行动的方法。
将必先明告吏士，申之以三令，以教操兵起居、旌旗指麾之变法。
This is to make the actions of the whole army neat and uniform. The general must first tell the soldiers clearly how to practice, and then repeatedly explain and explain clearly, and then teach the combat actions and the methods to adopt corresponding actions according to the changes of the flag command signal.
