Logistics is the ball and chain of armoured warfare. Military intelligence is a contradiction of terms. 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 will be.
War is like love.
To triumph, you must make contact. 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.
