Ceilings, and (knowing when satellites are passing overhead) when things need to be under ceilings.

I assume that most militaries have satellites with radars that can penetrate most ceilings to see planes in hangars etc. Most militaries also have access to some high orbit satellites that have 24x7 coverage of an area, and then some low orbit satellites which fly overhead every few hours and can grab high res shots. The combination makes it very hard to sneak a secret plane from one building to another between orbit…

You're going to have to define "most"

I'm pretty sure "no" militaries have 24/7 coverage of any area on the planet.

For reference here is footage from an apache gun killing a civilian reporter in Baghdad in 2007: https://commons.wikimedia.org/w/index.php?title=File%3AColla... So I'm fairly certain this is what most drone operators will see on the screen. This video is over 13 years old though, so current optics are probably much more advanced than what was deployed in iraq. Near-future drones can also probably use 5G networks to t…

This doesn't look like drone footage to me. From the flight pattern (left hand circle), this looks more like an AC-130 gun ship. Drones carry rockets/missiles, and this is clearly a large caliber machine gun being used.

If enough people were to use identically looking umbrellas it would be very hard indeed to track individuals passing below bridges and roofs. In Tokyo there is already a prevalent style for umbrellas: The transparent model you can see in the 1982 cult film Blade Runner.

A good friend of mine had the chance to see such a van while working for the French Navy. The operator even showed him a (somewhat blurry) real-time view of my friend's Mac desktop in the building next door... (This happened in the early 90s in Toulon arsenal).

That sounds like Tempest, and I somehow doubt that they actually showed him that.

It's not that Tempest was ever a secret, There was advertising for countermeasures (metal screens for Windows, just like you have in your microwave) in the mid 1980s.

Yet, the US has pretty much been kept at bay from Irak and Afghanistan, go figure... In general, the US army is not equipped for guerilla-style warfare, and especially not on US soil. Local PD are another story on this point, but far less equipped.

On one hand it’s clear that a guérilla campaign is fully capable of resisting a first class army for a long period of time; this has been clear since the 1970s. What people tend to ignore is that the defenders do this while sustaining much higher casualties . Oh, and civilian casualties are typically an order of magnitude higher because high explosives aren’t very discriminatory. On one hand, that’s an interesting di…

>What people tend to ignore is that the defenders do this while sustaining much higher casualties

Is this supposed to be a good thing for the defender? The us has been there for more than a decade and the defenders weren't running out of combatants.

I don't know if it would be effective at hiding you beyond the next few years when more comprehensive systems are in place, but I think a simple circuit that randomly blinks an IR LED would be handy. Something like an an LED throwie, but with random cycling. Put a bunch of them around and you'll probably screw up most cheap CCDs by forcing them to constantly adjust their exposure. Sure, a cheap filter can defeat them…

Thermal IR doesn’t pick those up.

They are analog signals right, rather than digital signatures. I think the author has conflated GPS receivers with smartphones that use them.

My guess would be that they use the same technique as radar-detector-detectors. Essentially sniffing out the RF radiation emitted by an RF receiver
