The footage from Ukraine is absolutely astonishing. This war is documented in such up close and personal ways, from above with drones, from soldiers POV with gopro like cameras. It's absolutely wild watching video on the internet taken form a battle, sometimes within 24 hours of it occurring.

Also interesting is how close these armor vs armor engagements are. A lot of modern doctrine seems to focus on distance but the videos from Ukraine show they're engaging in "drive by shooting" type ranges.
