You fight like you train.
A pint of sweat, saves a gallon of blood.
A good plan violently executed now is better than a perfect plan executed next week.
Unless you do your best, the day will come when, tired and hungry, you will halt just short of the goal you were ordered to reach, and by halting you will make useless the efforts and deaths of thousands.
Lack of orders is no excuse for inaction.
Battle is an orgy of disorder.
