The author offers no major new insights on the effectiveness of drones. His counter argument is against the maximalists who claim quadcopters are revolutionising warfare and render armour and artillery obsolete. But nobody serious ever suggested that. The same way tanks are relevant despite rpgs. They simply represent a new element in the battlefield, and a useful one as well. The fact that they are not ideally suited for dropping bombs doesn't matter. They are great for surveillance and giving units situational awareness, and the fact that they can occasionally be used to attack targets that otherwise would be impossible simply augments their usefulness. The article is interesting,
but it's attacking a straw man. I have a great respect for the ukrainian armed forces
but to be perfectly honest their combat effectiveness is not exactly world beating. The suggestion that NATO should be taking lessons from how Ukraine is fighting Russia is odd.
