I am going to make an assumption: you were never in an infantry unit. That being said: your house is never a fortress. It is a trap. It can be set on fire, it is a target for those on the outside, to pump rounds into and unless your walls are solid rock at least a foot thick, those rounds will hit someone.Houses around you are concealment for assaulting forces. It will not repel someone with a vehicle who drives into a wall.My current home feels almost indefensible by just 2 occupants. Every one of the 4 walls have large windows.
If things hit the fan, this would not serve as a fortress at all. If under attack, I won't turn on the lights inside the house of course, but I have my hands full here. Installed a couple if cameras, but that's only good as long as you have wifi and power.
Any suggestions, or what are you doing if you're in a similar situation?
You can harden it somewhat to allow you to get out at your choice of egress, but it will be breached.
When SHTF, your best bet it to not wall yourself inside,
