Not strategies or tactics...

...but rather objectives.

"Rule 1, on page 1 of the book of war, is: "Do not march on Moscow". Various people have tried it, Napoleon and Hitler, and it is no good. That is the first rule. I do not know whether your Lordships will know Rule 2 of war. It is: "Do not go fighting with your land armies in China". It is a vast country, with no clearly defined objectives."

Field Marshal Montgomery

We will never know if that mythical book goes on to mention Afghanistan, Mesopotamia and Persia.
