Ukraine has shown effectively that drones can effectively destroy tanks and armor and.......artillery
—
Only according to the videos posted. Other than those videos, there is no evidence of how the vehicles were destroyed. Most analysts believe artillery destroyed most of the vehicles; manpads and drone account for a much smaller percent.
Arty rounds are even cheaper than drones.
There is overlap. Cheapest drones are $400. Most expensive artillery rounds are over $20,000.
I take your point but my lost point was that drones can effectively seek out, actually see and then destroy artillery
Artillery to be accurate requires spotters. Drones can be spotter/killers it seems to me. I guess the drones can spot or the guns ad not need the killer capability to be effective
