I believe the surveillance drones, like the one pictured below, are responsible for a lot of the artillery kills.
The camera has a thermal mode which would make finding the artillery pieces easy to find, even if they are parked under the trees.
Several months ago, PIF posted information on a computerized battle management computer system. Perhaps, this system is also helping to destroy ruzzian hardware.
For example, when a drone spots a target, it would upload the target coordinates into the battle management computer system which would then identify any UKR asset capable of hitting the target within a 30 minute window.
PIF...have you seen anymore information on the battle management computer system?
No I have not. That was last year I think.
