Prepping for the future in your chosen retreat location

[Clansmen63]

An all too real scenario and one that would require a great deal of thought and preparation based upon your own circumstance.
As the Viet Cong Punji Sticks have already been mentioned, it is also worth remembering that the Viet Cong utilised many improvised weapons (some to a greater or lesser success rate than others) in harassing the American Army but more so in protecting their Cu Chi Tunnels. One of the ploys that they used (just to waste the G.I.'s time and mame and injure as many as they could) was to heavily defend areas with improvised weapons and Punji sticks in places that had nothing that required any defenses, (this was seperate to the defenses that they placed on paths, streams, etc.) At the begining the G.I.'s had to physically make their way through to check the area out just to find there was nothing there, later they just called in air strikes. So if this were a possibility and suitable for your own situation then something along these lines could be utelised as part of your own defenses in outlying areas surrounding your own patch, after all the mob can't call in an air strike and if they sustain enough injuries getting through such defenses just to find out it was for nothing, then it may deter them from investigating other areas with similar defenses. Obviously it wouldn't deter them if they could see your vegetable plot and chicken coops as then it would be obvious that there was a reward at the end and so make them even more determined.
