The original BCB Ultimate Survival Kit, USAF Aircrew Version, was developed and modified in collaboration with the United States Air Force. It is based on the Ultimate Survival Kit (UK Version), but is better supplied and geared toward use by the US military (NATO approved NSN 8465-99-270-7742). Now we have taken the USAF Aircrew Version of the Ultimate Survival Kit and improved it, still further, by upgrading some items and adding even more of the survival supplies that one might need in a survival situation.
Speaking of making mistakes here’s one of mine. One of the first things I ‘put back’ (as my Mom use to say in the fall before my Dad was out of work due to bad weather at the quarry), was a couple of extra bottles of vegetable oil. Well, other stuff got in front of them on the shelf and pretty soon they were 3 or 4 years old. Yes, they were rancid when I opened them. Taught me a good lesson on keeping track of what you have and using it before it goes bad. They are marked ‘not to eat’ and are now used to fuel some lanterns outside when we have cookouts.
If an alternate location is not practical, consider storing items at various locations around your home.  Not everything needs to be on shelves in the basement.  Spread things out so that if the basement gets flooded, you still have dry items in the upstairs bedroom.  Use your imagination and don’t forget to do the very best you can to package everything so it is resistant to moisture and pests.
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.
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
