Four points to think of in your survival planning
1) Do not become a obvious target for those who can and will want to hurt you. Either be inconspicuous and stay out of sight, or find a good cover story for what you do, (maybe hiding in plain sight) (such as a hobby like Paint Ball, Civil War or other Reenacting, Camping club, like I am a member of your State's Self Defense Force etc. to draw attention away from your prepping) or be and make it known to potential bad guys that you are strong enough to seriously hurt them so that they are afraid of messing with you.
2) Be aware that a regular well armed military force can destroy any target with its air power and precision guided munitions and heavy weapons, survival against such a foe requires being hidden. A good idea in this event is to copy the Viet Cong and the current Taliban, and go "underground" in hides.
3) Don't ever allow yourself to become a refugee. Always retain control over your destiny. Stake out your turf, make your plans and make sure that you never allow yourself to become panicked into mindless flight or obedience to the whim of a government official.
4) Never give up the ability to or the desire to resist. A very important psychological element in survival and personal and retreat protection is to make sure a "Bad Guy" who messes with you knows that even if he wins he looses. Make sure that a fight with you is a bad idea. That is the best way to ensure that you don't have to fight very often.
