Rommel: Infantry Attacks
<<Infantry Attacks>>, from Erwin Rommel. Thats fantastic in the view of infantry tactics.Still a lot of useful tips applicable today.
My edition has A LOT of tactical illustrations (point of view, shemas).
That's a book you can re-read and re-read without being bored.Bring it with you.When you have a little 10 minutes, read it.
True fitness is task-oriented.
