I thought I would add some input to this thread as my own personal interest in German WWII Uniforms and equipment dates back a good 35+ Years !
Getting involved with German WWII reenacting has shed much light on this topic versus just what is seen in books or online. Unlike the U.S. or British
army of WWII which had simple, basic Army uniforms the Germans used numerous colors, materials, and patterns. The enclosed photo depicts many
different Tunic shades that were used. That being said the Trousers were along the same lines in diversity as well. The uniform colors depicted by K&C
on their Wehrmacht series is quite correct and depicts the more commonly seen match of Trousers and Tunics, especially in the first few years of the war.
Hope this helps !
