Weaponized Surveillance
"Is this the hill you want to die on?"... a phrase showing the three aspects of surveillance: 1) I can see you but you can't see me 2) "I can see you coming from a mile away" and 3) I can resist falling weapons but can use falling weapons. The first use of hot air balloons was war (seeing, trespassing, dropping fire). The most obvious restriction of drones is communication with "the brains of the operation" until AI or GPS-guidance removed the necessity of radio communications in long range attack drones. The method to resist weaponized surveillance is "grey man" disguises. I love both rodents and cats so I was watching farm cats hunting mice in a quonset equipment storage building... They meowed loudly then sat in an open area and licked their paws as if they weren't paying attention. House mice have poor long distance vision so they would sneak closer and closer to the cat to get a better look... Until they were too close to get away from the surprise attack of the cat who was always watching... Curiosity killed the... mice. Portability is a bit more difficult when you are trying to protect a large amount of something and also when spreading that stuff around so any losses are a smaller percentage than the total. This also applies to data on the internet or similar transmitted data situation. A new factor to consider is satellites that are interconnected with lasers can measure gravity of the earth's surface very accurately (the speed of the satellite varies based on the influence of gravity so two satellites passing over the same point can triangulate the surface gravity at that point). Hiding underground has been the go-to method for animals and people alike (and the stuff they are storing). The average local density of the entire underground area needs to be calculated to remain undetected this way. Of course gravity and "muon tomography" can be added to low flying drones too for detecting small underground "anomalies"... A technology set that will be needed to de-mine war zones by farmers seeking to farm there again.
