do you know where I can find all of the weapons used by Germans and Soviet's during WWII.

What kind of weapons are you looking for? Personal weapons, squad based weapons, AFV's, Aircraft, Artillery...ect? If you specify just a little bit more, we could probably help you narrow down your search significantly.
