I have enjoyed reading "Infantry Attacks",
which was required reading for German
officers in training, and was issued in '43
or '44 in English as reading for American
officers (to know what to expect). It's the
story of the experiences of a new officer in
WWI and the lessons he learned, organized and
written for professionals. Very good and good reading. Oh, yeah, the author is Erwin
Rommel. Should be easy to find.
