So, if we're going to get a Campaign/strategic level in CMX, then what type do we want? As I see it there are two types of campaign that could be used. they are:
a) A grand campaign, where you control troops fighting to complete objectives, such as the D-day landings or the battle of the bulge. you would fight battles over a map, switching from area to area over the wider battlefield.
a smaller campaign, following a smaller number of troops who get carried over from battle to battle, gaining experiance and taking casualties as the war progresses.
A has the advantages of being able to fight a large scale campain, controling the macro movements of units, then fighting out the battles in a normal CM style.
B on the other hand allows you to get to know the troops that you command, and makes any losses more involved. you are fighting to protect your men, rarther than going all out to win the battle.
