Drone 1 (or any other means) destroys the canopy. Drones 2-10 are no longer hindered by said canopy and deliver their payload with extreme and dynamic precision.
Remember that the argument was basically that drones can do nothing useful in (heavily) forested terrain. They can with a little bit of creativity.
I guess we live in different regions. Everything north of Estonia/Denmark is thick spruce and pine forest. I’ve seen what artillery does to these trees, but I’d be hesitant to say a drone could lift something heavy enough to serve like Vietnam war era ”daisy cutters”. Artillery explodes closer to the forest floor.
