Something that has been abused by both sides at livland is tanks going through trees and leaves my idea is that tanks cannot pass through logs while in combat as when tanks can run into a forest it is impossible to sink them and makes it so that tank combat is a waste of materials rather only used to counter drilling/drilling rather then for movecraft supremacy on the battlefield.
Another way you could fix this is make it so tank shells go through logs and leaves and logs and leaves do not obstruct the barrel.
