I've played battles in meta campaign, including infantry regiments and mechanised brigades with several tank battalions and infantry battalions under my command with good heavy arty support. Maps were about 3x3km. The tasks were not to capture the flags and casualties were tracked from battle to battle.

In my opinion, big battles are the only way to get the real feeling of beatiful CMBB engine and get real taste of WWII: you begin to value the arty and HMGs and any weird results of individual engagements become negligeable due to scale. And necessity to mind your losses (enemy can switch reinforcements to your sector and you might be unable to consolidate your gains in next battles) makes the entire thing much more demaning.
