Followers of James Wesley Rawles often prepare for multiple scenarios with fortified and well-equipped rural survival retreats. This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster. Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region. They emphasize practical self-sufficiency and homesteading skills.
I’ll take a person with common sense over one who has a lot of survival knowledge and skills. There is too much emphasis out there on wilderness survival. That will be a rarely needed skill set. More common will be urban survival, and suburban survival. Age and physical condition will have more to do with being able to survive a long-term disaster. As a senior I have difficulty convincing myself and my peers that hard core survival skills will be possible or necessary. We can only prepare for those things we feel we have any chance to survive anyway.
Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
Bossy, know-it-all, and super preppers are dangerous to everyone that is part of a group of people trying to help each other survive. Too often preppers tend to undervalue someone who may not fit the mold they are trying to fill. They discount someone not physically as capable without realizing wisdom and common sense gathered over a lifetime can often outweigh and/or supplement their own preps. Often long-term survival requires skills that are quiet, less visible, and more subtle but will keep you comfortable longer. The end goal is re-establishing normalcy in society.
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.
I.N.C.H. pack: I'm Never Coming Home pack. (It is another name for a Bug Out Bag. often used by those trying to show that they are experts in the preparedness field.) A pack containing everything needed to walk out into the woods and never return to society. It is a heavy pack loaded with the gear needed to accomplish any wilderness task, from building shelter to gaining food, designed to allow someone to survive indefinitely in the woods. This requires skills as well as proper selection of equipment, as one can only carry so much. For example, instead of carrying food, one carries seeds, steel traps, a longbow, reel spinners and other fishing gear.
Astronauts are provided with survival kits due to the difficulty of predicting where a spacecraft will land on its return to earth, especially in the case of an equipment failure. In early US space flights, the kit was optimised for survival at sea; the one provided for John Glenn on the first American space flight in Friendship 7 contained "a life raft, pocket knife, signaling mirror, shark repellent, seawater desalting tablets, sunscreen, soap, first aid kit, and other items". A survival kit was provided for the Apollo program which was "...designed to provide a 48-hour postlanding (water or land) survival capability for three crewmen between 40 degrees North and South latitudes". It contained "a survival radio, a survival light assembly, desalter kits, a machete, sunglasses, water cans, sun lotion, a blanket, a pocket knife, netting and foam pads".
Another wave of survivalism began after the September 11, 2001, attacks and subsequent bombings in Bali, Madrid, and London. This resurgence of interest in survivalism appears to be as strong as the 1970s era focus on the topic. The fear of war, avian influenza, energy shortages, environmental disasters, and global climate change, coupled with economic uncertainty and the apparent vulnerability of humanity after the 2004 Indian Ocean earthquake and tsunami and Hurricane Katrina, have increased interest in survivalism topics.
The compass will get you moving in the right direction but when night descends you’ll need a strong dependable light source and the J5 Tactical flashlight is that and more. The J5 produces an incredibly intense beam from a single AA battery. It’s essential survival gear that can be seen from miles away so even if you can’t see anyone else there’s a good chance someone else will see you.
