@ncscswitch:
None.
You can;t even get above 50% for 3 battles if you go for all 3.
It can be done. It was done to me:
I had another player attack Norway, West Russia AND Ukraine R1:
3 inf, tank, ftr > Norway
6 inf, art, tank > west Russia
3 inf, art, 2 tank, ftr > ukraine
Lucky son of a gun won all three… handily!
Results:
Norway - 2 inf, tank,ftr (lost 1 inf!!)
West Russia - 3 inf, art, tank (lost 3 inf)
Ukraine - tank, ftr (took ukraine!)
This is a tourney game too. I probably would quit a ‘normal’ game at that point, but alas, I played on.
