Definitely a Fulda Gap theater. From Dresden (Germany) to Prague (Czech Republic), including the Alps (Austria and Switzerland).
A Cold War context. Large scale armored forces. The NATO and Warsaw Pact plans are now being released, a help for the campaigns and missions. OPLAN 4102 and "Seven Days to the River Rhine". ABLE ARCHER 83.
We have SRTM terrain data and OpenStreetMap planimetric vectorial data, all public access and open data.
No tactical nuclear weapons :)
By the way, we are making 48 years from being toasted because of a provable Cuba invasion (October 27-29, 1962). You can be grateful of the possibility to celebrate that.
