Head of Ukraine’s national foreign intelligence service – “We have studied…the strengths and weaknesses of the enemy. We are aware of Russia’s long-term plans…at least until 2030.”
That's just the end effect though, you still need support from artillery, air defense, anti armor, combat engineering, and a ton more to enable those rates. Drones are the tip of the force multiplying stack, they wouldn't be effective by themselves.
Air defense for example causes very few casualties, only a couple of pilots. But it enables the drones to fly without being shot down quickly. It's an enabler, a force multiplier for the drones. If you didn't have air defense, you'd get a lot less effective than just the 1% fewer direct casualties would suggest.
I assumed these are small fpv drones? They have kind of broken the traditional warfare dynamics and are more like ground force+ without the traditional air to air susceptibility.
