reworking the campaigns into theatres rather then operations
-the moscow and Stalingrad campaigns could be combined together and with that you could also at krusk and Leningrad maps/fronts in there
-normandy could expand to have Carenten city map, and have sword aswell as juno beach fronts
-berlin could be renamed to the 1945 eastern theatre with adding the siege of kustrin and schwedt
-tunisia could just be rebranded as the Mediterranean and Middle East theatre to inculde Sicily, toburk, El-alamein and Cyrenaica
in additon to this you could add the western 1945 theatre for a american close of the war adding a battle of the bulge ( aware) and americas advence into german aswell as the 1945 Italian front
the battle of the bulge can have bastogne, this way we can have both sides attacking and defending.
battle at prum and ST. Vith are can also be incudled in the battle of the bulge
for the italian front, bologna, the gothic line and the port of rimini (again aware)
and last one is to add a 1939 theatre, inculding the battle for france, dunkirk and Rotterdam to offer the french/british forces vs german forces in intresting locations
