I see the lack of a fast and not to costly retreat point on the OKW faction kind of bad, you see, all other factions can have a retreat point by just spending in a building or a particulary unit, while OKW must use the HQ medic halftrack to have it which isn't a good plan because it leaves you to vulnerable to mortar fire and then you lost a production build that cost 35 fuel like is nothing. It can't even move fast enough to leave the place because now is in combat state, while the USF medic/major can easily retreat from a arty strike or something like that, the soviet is really durable and cheap like the brits.

A option could be that Sturmofficer could have a retreat point ability or bunkers with this ability, like the soviet or brits forward estructure.
