Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper. Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses, have been suggested for survival retreats.
The 5-in-1 paracord bracelet slips on with ease and stays fashionably in the background until or unless the situation on the ground takes a turn for the worse. That’s when they spring into action. Should you need to get a fire going in a hurry there’s the fire starter kit comprised of flint and scraper. While you’re warming up by the fire take the lay of the land with the mini compass. There’s also what must be the world’s most compact emergency knife and should you need it a powerful emergency whistle that will project up to 100 decibels of life saving sound. Essential survival gear especially if you have the kids with you.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
