I can see that being kinda broken with current T3. I mean the SU-76 spam
Purpose of industry is to spam tanks.
Quadmount spam would be unreal.
M5 is not a tank, it should not be affected.
I'm not sure about this. I mean, you cannot get something for free. You must sacrafice something for that extra fuel/lower cost. Manpower or ammo. There is no other way. It's just current way of boosting fuel, that needs to be change cause it's broken.
Commander's abilities also a resource. And its not like industry with change i proposed would be good for anything aside cheap tank spam.
