This review is from: The German Army 1939-45 (1): Blitzkrieg: Blitzkrieg v. 1 (Men-at-Arms) (Paperback)
This book covers the development of German Army uniforms during the years 1939-1940. It is NOT about weapons, equipment, tactics or army life. Neither is a lot of information about the campaigns in Poland, Denmark and Norway, the Low Countries and the Battle of France in this volume.
But if you are interested in uniforms it is a very good introduction (albeit reading about every single buttonhole can be a bit boring ;) ).
The illustrations are excellent.
