The German military symbols system was a superb method of indicating on maps and in publications what a unit was, and what its component parts were. Other books in English have attempted to show how the system worked, and what the symbols were, but none can compare with the sheer detail and comprehensive nature of this intelligence manual published jointly by American and British Intelligence in 1944. Every level of formations is covered, and every arm and service. Naturally German Army symbols predominate, but the Luftwaffe and the German Navy are also included. This reference text should be on the shelf of every military historian who is involved or interested in the German Forces during World War Two.
