Fpv drones are EXTREMELY easy to trace, as well as trace back to the controller, it’s like making a big fire in the dead of night, everyone with the ability to track signals knows exactly where you and where that drone is. Interrupting the signal with a jammer makes the drone useless (or return home, which is worse…)
So the preference is to use drones that pilot themselves or have some sort of directional communication (light/laser), these are considerably more expensive and not many places make them, which allows intelligence agencies (like mossad, cia) to link the seller and buyer.
But also worth noting, drones have been in military use for decades, my country made their first military drones in 1986 – so using them isn’t really “news”…
