For the farmers, be sure you have lots of open space outside of your defenses. Fall trees or use ditches to stop vehicle traffic, make the pos’s get out and walk. Ideally you want as big of a clearing between the vehicle obstacles and the personnel stuff. the reason for that big open field is so all the deer rifles can “thin” the herd. A text book situation would give you at least 500 yards/meters of cleared space (no stumps, no ditches and as flat as you can make it) then the wire. With your positions behind it.
