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.
Is there a pro-Russian one? Any reporting or combat footage, at least what's been posted on Reddit, has been pro-Ukranian, and the Ukranian losses are underreported.
It's not warmongering though; Ukraine never asked for it, it's a war of aggression from the Russian side. I also don't think the soldiers depicted asked for any of that, but I doubt they were offered much of a choice in the matter.
https://simplicius76.substack.com/ is in the top 10 subscribed substacks. He posts videos supporting points he makes, and you can find drones attacks. His analysis and predictions are more accurate than pro-Ukrainian pundits, and draws on information from within Ukraine (speeches at the Rada, Ukrainian commander interviews, posts) and Russia.
