I posted this on the GTOS forums a while ago. A fantastic PDF resource! I found this comprehensive book in both PDF and EPUB. It looks really useful. I am not sure it is still under copy right or not. (I think the PDF is much better.) From this site: https://archive.org/details/tractors-29177010-Encyclopedia-of-Weapons-of-World-War-II This should certainly help with this game and others.
