Timothy Zahn said this quote

Leadership and obedience are the two legs on which a warrior's life is balanced. Without both, victory cannot be achieved.Leadership depends on information and comprehension. Not so obedience. Sometimes a commander may choose to share details of his plan. Often he may not. In either case, obedience must be instant and complete.Such automatic response relies on trust between commander and those commanded. And that trust can only be obtained through leadership.
