Reddit mentions of United States Air Force Search and Rescue Survival Training: Af Regulation 64-4

I have been posting this in relevant places to people I think might take it into consideration (and this seems like a relevant comment chain):

You can disaster/survival prep very quickly. Buy a water filtration system (I prefer the Platypus brand gravity filter) and at least a couple spare filters. Alternatively, you can purify water with bleach (info here). Buy at least 2 weeks of canned food that you won't touch for at least a few days after the event (unless you plan to be moving), and eat all perishables first. Dry beans and rice are better for your calorie/weight ratio. Buy a gun and a decent amount of ammo and get familiar with using it safely. You should have a decent first aid kit, with a focus on antiseptics and sterile bandages. Also, a hand crank or solar battery charger, which can be found for around $20 combined with a flashlight and radio. Bam!, you're now better prepped than 95+% of the population.

Some other additional items: MEDICATION RESERVES (if possible to acquire), flashlights, hunting knife, rope/twine/parachute cord, tarp, Bic lighters, padlocks & chains, enough gas to drive to a location you believe would be safe, road atlas, hiking backpack.

I recognize this kind of preparation is a touchy subject, but in this day and age, I would encourage you to look at the world around us and maybe see that we could be in a more precarious position than we would like, with only a natural disaster or something worse standing between civil society and relative chaos. I would hope that we would never come to a point in which gear like this might be necessary, but it is better to build dikes than just to pray for sunshine.

*This is a simplified, but relatively comprehensive survival prep guide for everything from natural disasters to total societal meltdown. I would encourage everyone to do at least some of it. The Boy Scout motto simply says "Be prepared". It doesn't say what to be prepared for.

**If you do choose to become a gunowner, I seriously cannot overstate the importance of taking a class or training with someone experienced that you trust. I would be happy to discuss guns (or any part of this guide) further if someone wants more advice on those.
