In this indispensable guide to readying your home retreat for any scenario, you will learn how to take proven designs for fortified structures and adapt them to your personal defense plan. A dedicated prepper and the author of Living on the Edge: A Family's Journey to Self-Sufficiency, F.J. Bohan takes you through the wide array of possible fortifications-including barbed-wire fences and entanglements, concrete posts and barriers, and simple but effective sandbags- that will enable you to determine the best course of action for your needs. Bohan details everything from the tried-and-true methods of cover used since the trenches of World War I to more modern methods such as the stout Jersey barrier. You'll see how to build bunkers and shelters using what's available to you, from logs to buried shipping containers or concrete sewer pipes. Whether you're planning to protect your family's home from armed insurgents during a time of unrest or designing a last-stand bunker complete with a system of trenches, tunnels, and manned fighting positions, Bohan's assessment of what's possible, practical, and affordable will put you on the right path to a safe and free future.
