Panzer Aces: German Tank Commanders in World War II by Franz Kurowski
Its nice to sometimes model a tank after a specific historical tank, such as Wittmann's Tiger I or Early's Pershing. The people covered are Franz Bake, Hermman Bix, Rudolf von Ribbentrop, Hans Bolter, Michael Wittman and Albert Ernst. If your looking for technical drawings, maps or lots of pictures then this isn't your book. It is a great book to read stories from real tankers though and get first hand stories of what life was like on the front lines.
