It's like this - if you do survival camping ( you know, backpack bringing in everything you need, no electricity etc ) then you'll probably survive.
If you just shoot a gun at a gun range, cool, but - well, shooting at a paper target that maybe moves forward towards you isn't going to do you much good. Those who do clay shooting with a shotgun, or maybe play paintball and NOT spam their shots, stand a better chance surviving. So does anyone who has taken any surmountable amount of martial arts.
Also, read the anarchist's cookbook.
Back in middle school I learned how to make home made napalm out of gasoline and styrofoam/soap flakes.
The result? I set a front lawn on fire - how? It wasn't burning out, so I stomped on it. Napalm stuck to my shoes. Shoes were on fire. I run around the front yard, setting footsteps ablaze.
