All battles are fought in the rain. Logistics is the ball and chain of armoured warfare. What gets you promoted from one rank, gets you killed in the next rank. A good plan today is better than a perfect plan tomorrow. If orders can be misunderstood, they have been.
War is like love.
Boldness becomes rarer, the higher the rank. Never reinforce failure. Failure reinforces itself. When a front line soldier overhears two General Staff officers conferring, he's fallen back too far. It isn't necessary to be an idiot to be a senior officer, but it sure helps.
