I dont know if this is a bug or intentional or what, but if an mg or mortar gets decrewed on a bridge tanks cant crush the remaining weapon. I have seen 2 decrewed mgs block a bridge entirely, the only way to remove the weapon is to attack ground on it until its dead, or crew it yourself and then move the men.
I even tried to run over them with my kingtiger.....still no crush. I can see how this would happen with the weapon needing to remian to be recrewed, but they should be crushable by tanks.
Ps for the admins: I dont know what section this should be in, as i dont know if its a bug or not. Thanks.
