After our recent Gush Katif removal of Jews because of their religion I have seen firsthand people who had to do a grid up bugout. I suggest having all 110/220 VAC gadgets in your pack at a minimum immersion boiler and battery charger these will take up a few grams and make your life easier by not wasting cooking fuel and lantern fuel, a lightweight extension cord may not be a bad idea either if room/weight permits. Sneaking into Gaza to protest (it felt freaky sneaking through Arab villages) reminded me of several important things which I hope to write about at length. But for starters: Have a decent heavy duty wire cutter for both concertina and cyclone fence. Only travel (if possible) with a trained group. Infrared cameras are mounted on drones for personnel detection, if you are in an unauthorized place have plans to defeat FLIR both cameras and airborne (an umbrella is pretty effective). The cellular system is operated totally at the whim of the powers that be not to mention acts of G-d destroying the infrastructure. The cellular system also allows you to be found within a few meters of your location every time your phone is powered up similar to GPS (AT&T in the USA allows you to access this function). Never assume that roads will be open even if it was open only hours ago! Be ready to have to get out and walk, or use a dirt bike. If a cash reward is offered and times are hard a person would be surprised that even hostile Arabs will call the army. Have a VERY detailed map of possible areas readable in red light and NVGs use map compass and GPS. A piece of aluminum foil with a pinhole behind your flashlight lens is good for reading a map, don’t forget your light discipline including infrared lights.
