How to push into enemy territory

The diagrams don't seem to be appearing properly. Also, I disagree with some of the advice, like "never, ever go into enemy territory if you don't control the middle". If the middle is contested, conducting a pincer movement by sneaking into enemy territory and doubling back is one of the best ways to settle that.

Exccelent guide but it is missing a few key points. You should've added more detail to certain parts and have more detailed illutrasions. Still a good guide that many people should follow.
