Regard your soldiers as your children, and they will follow you into the deepest valleys; look upon them as your own beloved sons, and they will stand by you even unto death.
Sun TzuUnless you know the mountains and the forests, the defiles and impasses, the lay of the marshes and swamps, you cannot maneuver with an armed force. Unless you use local guides, you cannot get the advantages of the land.
Sun TzuHence the saying: The enlightened ruler lays his plans well ahead; the good general cultivates his resources.
Sun Tzu
