Prince of Eckmühl
The moving back and forth is basically still there, although entrenched and fortified units now hold much longer.
This is indeed one of the oddest aspects of these games...
I'm not privy to the internal workings of the game. Like the rest of you, I'm reduced to what's observable, and that can sometimes seem a bit odd.
There's a scene in the second or third episode of Band of Brothers where "Easy Company" is subjected to a combined arms attack. Their situation is made all the more dire by the fact that elite airborne companies to their left and right have fallen back in disarray, leaving E Coy to its own devices. In the end, it's not a counterattack from the rest of the battalion that saves them, but the arrival of armor from the Allied Beach-head.
Sound like airborne assault?
If there's really something wrong, bang the drum loudly. But, please, keep an open mind.
Government is the opiate of the masses.
