Essentials for surviving a SHTF situation:

- Water. Lots of water. Essential for life

- canned food. No cooking required

- some sort of fire-making device. Not a lighter or matches, but a flint or magnesium is good

- knife

- rifle & lots of ammo. AR-15 preferred. Good for hunting too

- body armor. Optional but good to have

- flashlights

- ham radios!
