Yes this is crazy, but it’s a pretty normal number, I think they are small drones used at the front lines for surveillance and attack.
Much like the UGV’s are ground drones used at the front lines for supply and rescue.
But Ukraine is clearly dominating on drones, and allegedly they are taking out Russians at a ratio of 8:1 now.

With the bigger drones that operate further behind enemy lines, Ukraine is dominating Russia 3:1.
