>>FLIR is infrared so unless your gun is hot, temp wise they’re no use and don’t see anything but heat. The only thing they could do is fly over areas looking for metal but it won’t tell them what kind and if they’re hidden vertically the signature footprint would be very small.
FLIR goes on drones that can stay aloft and scan large areas and see folks as they bury the weapons.
They won’t start the raids until long after the drones start watching the woods near concentrations of dwellings.
Mountain folks have the advantage. It’d take time to get that many drones up and running and searching. Plus area of dense forest like where I live. Just as an example. A PVC pipe sealed on one end, a screw cap on the other. A dissembled M1 carbine oiled and vacuumed packed along with ammunition. The PVC pipe is slightly heated, the package inserted and the screw cap tightened. Bury it vertical. You’re looking at a metal object buried like three feet down with a diameter of say two or three inches (breech housing and trigger assembly) then broadcast small nails in a wide area,or not. My family has talked about various hiding methods and this was just one.
