Yes, the Russians are using the same tactics, strategy, and logistics that they used during the Great Patriotic War. Drafting a huge conscript army, sending it mal-equipped to defend fixed positions, from which the leadership dictates that they cannot retreat, using "blocking units" to enforce the no-retreat order--it's all straight out of the GPW playbook.
But why should it be any different? Russia hasn't fought a significant conventional war since the Great Patriotic War.*
Contrast that with the United States Army. The US Army has been engaged in a major conventional war pretty regularly from 1941 to the present day. Korea; Vietnam, Iraq, Iraq again--since 1941, the US Army has never gone more than 15 years without being engaged in a significant conventional war.
So that does two things. First, it means that your senior officers/NCOs always have combat experience. But beyond that, it gives the Pentagon a real-world test to develop new battle plans and see what works and what doesn't.
Russia doesn't have that. Their most recent test of what works and what doesn't is the GPW. But aside from being 80 years ago--and there have been a few technological developments in the last 80 years, this isn't the Great Patriotic War:
Russia doesn't have nearly as large a population today as it did in 1941 (194M vs 144M). So the available pool of conscripts is about one-quarter smaller;
Ukraine isn't fighting a two-front war, with the Western Allies keeping 40% of its army engaged in places like North Africa, Italy, and France;
Russia isn't getting supplies from the United States.
The last one is the really big one that has been ignored by Soviet/Russia historiography. The Soviet Union was only available to fight because of Lend-Lease supplies. The Russians have long written about the T-34 as being the great achievement of Russian manufacturing/logistics that won the war (ignoring the enormous number of Patton and Sherman tanks that the Red Army used). But the T-34 was built on an American chassis with American steel. It ran on American diesel and fired American ammunition. It was crewed by guys wearing American boots and eating Spam.
Russia supplied the meat for the grinder in the GPW, but it was a victory of American manufacturing and technology.
Their historiography/propaganda leaves off that second bit. So now they're going to just feed meat into the grinder. But without the manufacturing and technology, all you get is ground meat. And that's what Russia is going to come away with.
* No, I'm not counting Afghanistan or Chechnya. Those were counter-insurgency operations. And they're very different from a significant conventional war against a national army that can field armor and artillery.
But it does raise the observation that before the Russians broke out the GPW playbook, they were running the Afghanistan playbook. That's what they expected--to quickly take over the capital, install a puppet regime, and then conduct a large counter-insurgency operation. That's reflected by the fact that they were sending in VDV units on aluminum BMPs in the first wave.
And no, I'm also not county Georgia any more than I am counting Panama or Grenada.
