Other than plywood on the windows I was wondering what are some realistic fortifcations for the home in a PAW. Here's my ideas.
Barbed wire/Constantia wire. A number of uses
2x4's for door jams. (cut a 2x4 at an angle the nail to the door and floor at an angle. That is if you were no longer going to use that door.)
Steel netting (Chicken wire or smaller) on the outsides of windows not covered in plywood ie top floor to keep objects from being threw inside of the home.
Foam the kind like you by to soundproof or the kind that is placed on a bed I have no clue what they are called but place them on the inside of windows for noise suppression.
Duct tape all windows and doors in case of chem or bio attack.
Ok my head hurts now.
