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.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
Every year in the US about 150 people die while out and about in national parks, more than 1,000 die in hunting-related incidents and thousands of backcountry enthusiasts get in deep trouble and require a Search and Rescue team to save them; with dozens of those folks dying while awaiting rescue. Most fatalities are the result of poor preparation. Bad weather descends and people get lost. They wander without water or shelter, often injuring themselves in the process. If they survive they often suffer frostbite, hypothermia, dehydration, trench foot or some combination of them all.
Say you're at work and a terrorist attack occurs. Roads are closed to any and all traffic but you only want to get home - even if that means walking. You may not want to grab your full on family pack in the car or you may not even be able to get to it. But you just want a light kit to get you through. How far is it to get home from wherever you may be? This get home kit should provide for 1-3 nights of traveling on foot till you make it home.
