With the new addition of the m3s truck bases are easily being raided, People always drive up to your walls and hop over and they can easily get out by dismantling a wall, You basically are forced to build inside buildings to prevent this from happening, i've also seen people get over walls with ADA aswell.. We need 2 wall high walls. I know you can techinically build watchtowers around your base, like in a sqaure or circle, but that takes too much time and resource.
