Or maybe asking just how many drones are there. as EW is a statistical thing, it cannot be scored in exact manner as one can never repeat the condition in testing range all the time. Thus why EW capability are scored statistically and ranged from "Fragile" to "Robust".
There's been a lot of drone bombardment in Kherson area. I think I even remember seeing a Leer-2 EW vehicle getting artied with help from a UAV spotter.
Comparatively, I really haven't seen anywhere near as much Ukrainian drone footage around Avdiivka relative to the amount of action there. To be fair, this is all just me spitballing, but I do think that there is a critical shortage of EW assets in the Dnieper grouping. Considering the likelihood of any strategically consequential outcome in Kherson, I can understand why high-value systems wouldn't be deployed there.
What's the point? It's not like anything will come out of Ukraine continuing to camp in Krynki. Might as well take a few extra casualties and save EW systems for more important areas.
