This is considered the most "pro-Russian" sub-Reddit, so it balances the Anglosphere deluge of pro-Ukrainian material pretty well. The most important poster is u/HeyHeyHayden, who's content is so important another user built a site to archive it: https://old.reddit.com/r/UkraineRussiaReport/comments/1pfjpx...

Hayden mostly compiles battlefield progress from Suriyak Maps (reputable Russian mapper) and AMK_Mapping (reputable pro-Ukrainian mapper). I think you can find both of them on Twitter.

On Youtube, I recommend WillyOAM (Australian infantryman turned journalist), MarkTakacs (Hungarian infantry officer who makes tactical analysis vids), Daniel Davis Deep Dive (retired US Army LtColonel, Desert Storm vet), and HistoryLegends (meme-heavy but generally well-researched battlefield progress vids).
