There is a whole list of "damage" that is not being represented in AH's ground game. For now, I believe they have tried to K.I.S.S., compare what can be damaged and to what degree can it be damaged. There is no "partial" damage, it is all or none. Engine, either working or not. Track, either working or not. Turret, all good or all damaged (why does damage automatically destroy both main gun and co-axial MG?). The bow MG is ALWAYS working until the entire tank is destroyed.
