But another issue…
There properly are a reason why AT isn’t in the game. Why need it, you have arty instead, otherwise there are alot of special units that should or could be included (German Sturm pioneers, British commandos, paratroopers, the german magnetic minefield that covered more or less all of the coast of England, elite panzer formations to name a few).
If the AT unit was included the russian forces would be more or less a wall of metal, and the germans dont have that much protection from the allies.
If things should be more correct there should be more space between US and Morocco, Russia should have the largest airforce (but they should only att/def with 2/2 max. (after all the russian airforce was the largest but after 2 weeks they were destroyed)).
Fortress Europe should be in place (which would stop any raiding force in europe, because the main guns would destroy as much allied ships as they would destroy troops… mmhh could create intresting games :)
you of couse could use the models from A&AP + A&A to create these special units (and they would create some very long games of trying to claim a foothold in europe and to force the other countries into submission) :)
well just thoughts
