I have studied numerous military strategy books, watched even more videos on the subject of the best locations to "hold up". You know, the best defensible locations. It would seem that the overall opinions seem to stress that defending the high ground is the soundest position to give a group the best opportunity to survive an encounter.
I figure there are four type of attacks that are to be expected. I just want some feedback on how full of it I am. I am actively searching for a bug out location and want to make sure it will be defensible. I may be full of it and I hope that you will tell me so if I am.
First: a single attacker
Second: a small group (7-10 persons) using standard weapons, including, but, not limited to firearms, bladed weapons, and bows.
Third: a medium sized group (10-25 persons) using advanced weapons, which would include but not limited to rifles, semi auto rifles, and automatic weapons, explosives, and electronic toys, such as drones and cameras. This group may be well organized and stealthy.
Fourth: this group will have over 25 persons, will move in heavy vehicles, may have heavy artillery, tanks, mortars, etc.. This group will likely be military or organized rejects from military group that they once belonged. They will be supplied and armed to the teeth in most respects.
Ok, what are the likely occurrence of these attacks after SHTF and giving that I may be able to see some of them coming from a distance, what are the chances of a well armed small to medium person defensive group defending a bug out retreat that occupies the high ground. I know this is incomplete and vague, but, I hope you can see a good enough picture to aid me in this mental exercise.
