So how would this RP play out? Would our characters be in close proximity? Or scattered all across the front line? I think the Eastern Front shindig had about a zillion battles. 

Or were you thinking of doing it in stages? Ya know, like:

Scenario #1: Eastern Poland

Scenario #2: Outskirts of Moscow

Scenario #3: Stalingrad

Scenario #4: Kharkov 

Scenario #5: Kursk

And so on, and so forth?
