Variation of Tactics · Blend Advantage and Disadvantage
Hence in the wise leader's plans, considerations of advantage and of disadvantage will be blended together. If our expectation of advantage be tempered in this way, we may succeed in accomplishing the essential part of our schemes.
Weigh gain and harm together. Seeing the gain keeps the work moving; seeing the harm keeps you out of trouble.
Variation of Tactics · The General's Responsibility
The general who thoroughly understands the advantages that accompany variation of tactics knows how to handle his troops. The general who does not understand these, may be well acquainted with the configuration of the country, yet he will not be able to turn his knowledge to practical account.
Without flexibility, knowing the terrain gets you no advantage from it, and knowing the favourable conditions gets you no use from your people.
