1. Utility knife
2. my mauser 48 rifle
3. canteen
4. matches or a lighter
5. mess kit
6. sleeping bag
7. tent, nothing is nicer than shelter
8. an extra set of clothing (you would be suprised how absolutly miserable you can be when your uncomfortable, and moral is one thing that needs to be kept up)
9. book or a journal, something I can use to help keep my sanity
10. MRE's (after I ran out I would raid local stores for food)
11. some sort of radio, preferrably hand crank, so I can attempt to contact other survivors.
thats really all I can think of right now. All of this stuff I comfortably carry in my rucksack.
