If you’ve ever been in combat in an urban environment, you know just how shitty of a decision it is to hole up in a room with only one entrance. If they control the entrance, they control the exit, and they have a lot more room and supplies outside than you could have in a bunker.No matter how fortified your structure is, unless you spend a CRAPLOAD of money, all they have to do is wait you out and can easily speed up your schedule to come out.Imagine how much pressure a buried container bunker must have to withstand and then realize that the whole thing is surrounded by metal that’s only about as thick as a saw blade. Now imagine if someone drives a truck or even just walks over your supposedly-hidden bunker?
