Apparently the Ukrainians have formed specialized FPV/Drone units to function as "cleanup" units.

One unit on the Avdiivka front is called "SHADOW" and what they do is they wait until a Russian assault has been shattered; then start flying drones equipped with incendiary devices around, looking for abandoned/knocked out Russian vehicles and then dropping said incendiaries down open hatches, etc.

Once a good fire is burning, move on to the next target; as the protective quality of the armour is destroyed by sustained fires.
