Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor[75] for any natural or man-made disaster[76] and "a clever way of drawing people’s attention to disaster preparedness".[75] The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything."[77] Though "there are some... who are seriously preparing for a zombie attack".[78]

This section may require cleanup to meet Wikipedia's quality standards. The specific problem is: Some blurbs are written as prose, others as definitions. I think we need to decide what it should to be: prose, or a list, and be consistent with it. Please help improve this section if you can.

While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.[30][31]

No one thinks they’re going to be trapped by whiteout conditions or separated from their group as night falls but it happens with alarming regularity. Don’t make things worse by being unprepared. These advanced Mylar emergency blankets cost less than 4 bucks each and weigh virtually nothing and yet can and do save lives. They’re waterproof, tear-resistant survival gear that comes in a pack of 5. As such there’s no excuse for not having them tucked away in your backpack or daypack when you set out. The very definition of essential survival gear for outdoorsmen of all stripes.
For personnel who are flying over large bodies of water, in additional to wearing a survival suit over cold water, a survival kit may have additional items such as a small self inflating raft to get the aircrewman out of cold or predator infested waters, flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still[4] or chemical desalinator kit now replaced by a hand pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.
A: When organizing materials in a tactical backpack there are certain fundamental rules to follow such as packing the sleeping bag at the bottom and placing most of your heaviest items in the center of the bag, with clothing like thermal tops and hiking pants etc above that. If you’re carrying a tent it should be lashed to the side of the pack. Survival gear – like most of the items reviewed above – is often small and light and should be distributed in the exterior pockets of the backpack where it can be easily accessed in an emergency. Place items related to the same task in separate pockets; i.e. place all your fire starting related items in the same ziplock bag and put them in one pocket then put your navigational aids together in another pocket. Things like emergency blankets and Mylar survival tents can go together in another pocket. While your tomahawk should be tucked away in the backpack, your knife should always be carried on your person. If you need to use your survival gear for any reason it should be returned to the same pocket you took it from so there’s no confusion if you need it again.

There are a few basics to remember when it comes to finding your way out of the wilderness like finding a stream and following it downhill. This will keep you near a water source and take you out of the worst weather toward civilization. However if the weather is bad and there are no streams to follow you’ll need another method of navigation: the compass.
The kits provided for Soviet and Russian Cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include "food rations, water bottles, warm clothing, rope for making a shelter using the capsule’s parachute, fish hooks and miscellaneous other survival gear". The TP-82 Cosmonaut survival pistol, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.[8]

I'm not quite crazy enough to say that epinephrine will help you survive the inevitable zombie apocalypse (you can go here for that). I'm just suggesting in a roundabout way that if you happened to be in a situation where something was trying to eat you, the increased heart rate and blood flow to your muscles brought on by a well-timed dose might just save your life.

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.
