There are entire subreddits dedicated to actual footage of drone effectiveness on the front lines... It's definitely not just psychological warfare. In some cases, the fiber optic lines crisscross fields so densely it looks like spider webs.
Or subreddit DroneCombat for drone specific posts, very NSFW too. And then UkraineWarVideoReport has a bit wider range or reports and links, so unlike those other two it's not combat footage only.
