I believe that theory of the "Meat Wave" came from "Meatgrinder: Russian Tactics in the Second Year of Its Invasion of Ukraine" from RUSI:
Also note that absence of evidence doesn't mean evidence of absence, so it may be possible that Russia is conducting these types of raids, but they have reduced the number of troops involved due to an inability to stage large scale attacks.
The original YouTube video from History Legends is here.
Thanks Ryan, I very much appreciate your expertise here. Personal aside, I sure wish we’d hit when Russia was weak. Thinking particularly when Prigozhin went rogue. We’ve squandered so many chances to seriously smack-down Putin and his bizarre delusions of grandeur.
I think the Ukrainians coined the term for this war. I never took it as a Red infantry tactic AKA Chosin Reservoir style. Russian POWS have described tactics of sending groups of a dozen or so to advance until they could not go further and dig in. Maybe they have all been killed, but nonetheless, they send it in the next dozen. Rinse and repeat. This is just the way I interpreted the term.
