"This is an essential book for everyone with an interest in the German Army and the First World War." False.  Light treatment and errors On page 73 there is even a picture of an Austro-Hungarian Uhlan helmet that is ascribed to Germany! Lots of nice pictures and a real update of the Nash book.  So a one volume 142 page one size fits all reference. Pictures are heavily Baden and Wurttemberg oriented. Added the section on reserves to the introduction. A very long paragraph but this one too misses that mark. Really nice paintings by Christa Hook.  About $20.  Is it worth it? Hardcover, nice binding, good looking. Lots of compiled data that comes out of Nachtrage und Berichtungungen Zum Deutchen Reichsheer.
