Drones are an emerging weapon platform, there is no question.
However, no matter how many drones a military has, if they cannot take and hold ground with an army, then attacking with drones is like Hitler hurling V-1 and V-2 weapons at England while losing ground and enormous amounts of men and material in the process.
This exactly what Russia is doing - they are resorting to "V weapons" while their Army is getting it's ass kicked.
Of course. Talking with my son last night about the Armata "deployment", I pointed out that the reliance on wonder-weapons is indicative of desperation. I just don't regard drones as wonder weapons in this era.
