The enemy has a dismaying habit of not doing what you think he will when you are planning an engagement.
Always have rally points and back up rally points.
If there is a way to misinterpret an order, it will be.
If you are going to have to fight, rest assured that it will be when you are feeling under the weather.
“Aim small.”
Qui frumentum necessariaque non praeparat, vincitur sine ferro.
He who does not prepare grain and necessities is defeated without a sword.
Publius Flavius Vegetius
De Re Militari
It is reported that Napoleon Bonaparte provided corollary to what Vegetius wrote, “An army marches on its stomach.”
Now we can add fuel/ energy to Napoleon’s stomach. See #19 about radios.
