Yep. Russia likes the “cauldron” and “artillery” methods of warfare. They are very, very good at them, too.
The USA seems to prefer air superiority and bombing people from the skies. Russia seems to like to shell people into submission with artillery, then go in and mop them up.
Still a long way to go in this conflict, but Russia has made some adjustments from the shaky early days, I think. They have a plan and are sticking with it.
It would be interesting to do some long-term studies about the kind of artillery shelling that the Russians favor.
I still remember the retaliation missile strikes on our Iraq base after we rubbed out Salami from Iran. There were a number of trauma injuries, if I recall correctly.
