Go to a website called watchpeopledie. The community sucks- it's basically a bunch of reddit fags who are into gore. But the content is there, and it's good. It's a good website, well categorized and curated and even archived. There's a category for "combat", and the vast majority of videos being uploaded there are from the current Russia vs. Ukraine conflict. Footage from both sides. Comments are cancer, but you don't have to read them. The combat footage is valuable learning material. For all the training you can do, actually *seeing* how a firefight plays out from a literal bird's eye view (via drone in high def) can teach you a lot. You can notice patterns in how soldiers behave in combat and shit like that. You can see how panic manifests in younger, less experienced men and compare that directly to the older, more experienced men. There are many firefights caught on film by civilians, fighting in trenches and shit. One of the best I saw, was a civilian drone filming a Russian infantry unit ambushing Ukies on a highway. It's amazing to see how the fight plays out as the men exchange rifle fire and grenades from like 40 feet away from each other. I've never heard that 1:5 kill ratio stat, that does seem bizarre for an attacking force to have that big of a difference in casualties. If anything, I'd expect it to be about even, or slightly skewed towards the Russians. I doubt this'll be a problem for you, but uh... gore warning, I guess if you go to that website. It's easy to go down a rabbit hole and discover you've just spent the last 2 hours watching cartels dismember people alive or w/e. There's some REALLY fucked up videos of Ukies committing horrific war crimes- worst I watched was them castrating a Russian PoW, laughing at him as he squirms in agony for a minute or two, before finally shooting him. The amount of effort it took for them to fucking castrate that poor bastard was absurd, I wonder if that made them feel manly? As I said above, there's lots of footage of Ukies torturing Russian prisoners, but very, very few videos of Russians doing the same to Ukie prisoners. And I've looked for them. If they existed, western media would never fucking shut up about it, and would present it as justification for more nations entering the war to stop the Russians from brutalizing their prisoners. Fucking clown world war is something else, isn't it? Very different from the conflicts I participated in.
