As the question says how do you use them, the ones that are on top of towers when you defend a castle for example. Some patches ago they were just cosmetic but recently I fought a siege battle on the most recent update and I saw one of my men using it and fired a couple of shots with it before he got shot, I tried to use it myself but it seems impossible. You just walk through it. Can the player use siege weapons on this mod for himself? Or it only used by engineers and npcs
