I was pretty much ok with the CM1 Front line system. I always viewed the kinks in it as how the lines settled after a mutual pullback for resupply and regroup. Was it perfect. No. Was it better than Campaign system that's largely a system of yesteryear. Yes. Somewhat disappointed that there is still a 'never' position towards operations or dynamic campaigns. That said, give us persistent damage, large enough maps, ammo dumps, and reinforcements then we have a CM1 de-facto operation. Some UI to review and pick units for next mission would be an evolution.
