Moby Games website says this about Panzer Elite Special Edition:

# New! Now command more than 100 different vehicles, including the German Tiger & American Sherman tanks.
# New! Comprehensive landscape and scenario editor.
# New! Campaigns against British and Russian forces in Winter & night modes.

100 different vehicles? I'm highly skeptical. Is that correct?
British and Russians? Winter and Night? Where is that? All I see is Desert, Italy, and Normandy. I don't remember any Russians in any of those campaigns.

Those are on the bonus disk. The 'Special Edition' contained a second disk that had all mods of the day, as well as the editors. I believe the bonus disk is seperate, free download for GOG customers.
I have not updated my portal for a long time. Most of the links still work.
