A friend of mine (Hi Frank!) made me aware of a great resource, yesterday. The Nafziger Orders of Battle Collection is hosted by the Combined Arms Research Library, and is freely available. I’ll quote the library website’s summary of the collection:
“The Nafziger Orders of Battle Collection contains a compilation of 7985 individual orders of battle from 1600 to 1945. It began with Nafziger’s interest in Napoleonic Wars, and steadily grew to other areas because of the gaming public’s interest in these highly detailed historical orders of battle…..Nearly all orders of battle break down to the regimental level.”
This may be one of those things that every historical wargamer in the world, except me, knows about already, but I thought I’d put up the link just the same.

I hate it when people find things like this or should I say my printer hates you as I`m trying to print the entire 2nd world war,lol.
Great find and quality bit of research by Nafziger
Well, hopefully, for your wallet, it’s a laser printer! By the way, that’s some nice looking 15mm heavy armor you have over on your blog.
Fantastic. The internet just blows my mind!
I have a few other mind-blowing resources in the Reference section in the menus to the left. The US Army Pictorial History of WW2 is particularly useful for WW2 painting and modeling.
