These individuals study End Times prophecy and believe that one of various scenarios might occur in their lifetime. While some Christians (and even people of other religions) believe that the Rapture will follow a period of Tribulation, others believe that the Rapture is imminent and will precede the Tribulation ("Pre-Trib Rapture"). There is a wide range of beliefs and attitudes in this group. They run the gamut from pacifist to armed camp, and from having no food stockpiles (leaving their sustenance up to God's providence) to storing decades' worth of food.
Not taking a cheap shot at the author, but wouldn’t the author fall into 1 or 2 of these categories? I think the human character of every individual harbors a little bit of all or several of these. Most, if not 100% of anyone prepping has in their specific individual plan – their family members. Each family member brings their own set of considerations (assets & liabilities) to the table. Are we to avoid/cast out these family members due to their nonconforming attributes? This eludes me to one of the categories you left out – The resistant/reluctant prepper. Because if you have a family there’s a strong chance you will have one of these, but they too come around in time.
Every survival kit and emergency preparedness plan should include emergency blankets and lights. Mylar blankets effectively reflect body heat, and can keep you warm throughout a cold night. Their extreme lightweight and compact size make them an ideal part of a survival kit. To ensure you have adequate light in the event of a power failure, chemical snap lights are a convenient solution that doesn’t rely on batteries. Many snap lights last for 12 hours or more, and have a five year shelf life, so you know they’ll be there for you when you need them.
When you go back to the last depressing days when we were in a survival mode, the last one the Y2K of course, before the 1970s, what had happened was you only saw this one element of survivalist, you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This is a very different one from that: you're seeing average people taking smart moves and moving in intelligent directions to prepare for the worst. (...) So survivalism in every way possible. Growing your own, self-sustaining, doing as much as you can to make it as best as you can on your own and it can happen in urban area, sub-urban area or the ex-urbans. And it also means becoming more and more tightly committed to your neighbors, your neighborhood, working together and understanding that we're all in this together and that when we help each other out that's going to be the best way forward.
If you have a proper survival knife with you when the weather closes in you can make an emergency shelter; if there’s the material available to do so. But it’s better just to make sure that whenever you venture into the woods for any length of time that you have the right survival gear with you and the Sundome 2 Person backpacking tent from Coleman is that survival gear.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
Further interest in the survivalist movement peaked in the early 1980s, with Howard Ruff's book How to Prosper During the Coming Bad Years and the publication in 1980 of Life After Doomsday by Bruce D. Clayton. Clayton's book, coinciding with a renewed arms race between the United States and Soviet Union, marked a shift in emphasis in preparations made by survivalists away from economic collapse, famine, and energy shortages—which were concerns in the 1970s—to nuclear war. In the early 1980s, science fiction writer Jerry Pournelle was an editor and columnist for Survive, a survivalist magazine, and was influential in the survivalist movement. Ragnar Benson's 1982 book Live Off The Land In The City And Country suggested rural survival retreats as both a preparedness measure and conscious lifestyle change.
The Missouri Information Analysis Center (MIAC) issued on February 20, 2009 a report intended for law enforcement personnel only entitled "The Modern Militia Movement," which described common symbols and media, including political bumper stickers, associated with militia members and domestic terrorists. The report appeared March 13, 2009 on WikiLeaks and a controversy ensued. It was claimed that the report was derived purely from publicly available trend data on militias. However, because the report included political profiling, on March 23, 2009 an apology letter was issued, explaining that the report would be edited to remove the inclusion of certain components. On March 25, 2009 MIAC was ordered to cease distribution of the report.
A: There’s a lot of overlap between the above question and this one but basically once you have your survival gear separated into different categories you’ll want to distribute it in the exterior pockets of the backpack where it can be easily accessed in an emergency. The MOLLE survival gear system devised by the armed forces for combat troops takes a modular approach to organization that’s also extremely flexible and allows you to configure your supply load in a way that makes the most sense for you. Rows of nylon webbing are distributed across a vest that’s worn under the backpack. You’re then able to attach various MOLLE compatible accessories and pouches – in this case containing your survival gear – to the vest. Additional pouches can be attached to webbing on the exterior of the backpack as well.
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?
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!
