Above all personal feelings and considerations and above all selfishness stands the iron law to which we everywhere must always remain true. A piece of spaghetti or a military unit can only be led from the front end. We can still lose this war. Logistics is the ball and chain of armoured warfare. When the situation is obscure, attack.
New weapons require new tactics.
Never put new wine into old bottles. You can't say civilization don't advance. For every war, they kill you a new way. There is only one purpose to which a whole society can be directed by a deliberate plan. That purpose is war, and there is no other.
