TM-E 30-451 Handbook on German Military Forces 1943-09-01
"The purpose of this handbook, which is a revision of TM 30-450 (17 December 1941), is to give both officers and enlisted men of the U. S. Army a better understanding of their principal enemy in Europe. In order to fight the Germans successfully, it is vital for the U. S. soldier to know at least in broad outline the manner in which the units of the German Armed Forces are trained, equipped, and organized, as well as something about the chain of command and the method of close cooperation between the various branches."
