This suggestion is mostly about weapon kits that applied to respective squads will make them balanced and effective in battle while maintaining uniqueness.
Note: sometimes AT weapons are not best for BR (M9 Bazooka at BR 3-4 for some USA squads) to not have an AT weapon that deletes any armor you may meet frontally into any part of the tank (especially considering that Japan and Germany dont have armor that can’t be killed frontally with said M9).
