The Organization and Order of Battle of Militaries In World War Ii: Volume I - Germany: Volume 1

If you are really passionate about the Second World War, especially OOB's then you might find some interesting information. To be honest Axis factbook or Wiki do a comparable job. There is too much information about who commanded the units rather than its components. A simple example: The 166th Infantry division. No OOB on its components, Welle type but 7 lines out of 10 are dedicated to who commanded the unit over the course of the war. It's really a very niche reference book, not sure why I ended up buying it, it brings very little to anything. There are much better books on the subject out there such as the series by Mitchan.
