Which is exactly why the MIC tried to turn artillery shells into high-tech wunderwaffe packed with proprietary guidance systems, instead of just making plain old shells.

I really don't think the MIC grasped how drones would make the old-fashioned low-tech shells so much more effective. No need to just blanket an area with massed shelling, no need to send in soldiers to do artillery spotting. Just send in some cheap drones to do the spotting for a relative handful of guns.
