My vision is to have a large table laid out to depict a larger section of the front lines, depicting a brigade/regiment footage. Multiple battlegroups would be deployed adjacent to one another, and the results of tactical encounters between a battlegroup and enemy forces would have lasting consequences at the operational scale.
Since I'm interested in the mid-war years, and in the eastern front, I'm going to set up my initial epic game in that period and locale.
The Germans will be strategically on the defensive in my initial game setup, with some mobile reserves for counterattacks or stiffening of other battlegroups.
I've gone back and forth between using a large table for a battalion sized game or using a campaign map to move operationally. Currently, I'm leaning towards using a long table to play a full reinforced battalion on the defense.
