If I was Putin I’d just read all the news about the “secret” spring offensive Ukraine is doing, when they’re launching their attack, where they’re striking, times, equipment etc.
It’s a real secret expect for what the news is saying.
Anyone with half a brain, that includes Putin, knows a counter offensive will come, so it’s hardly a secret. The particulars are what everyone can only guess at. But this much you know, it won’t be using WWI trench warfare human wave tactics. The Ukrainians are getting weapons and training from western nations that use highly mobile, combined arms, tactics. It is highly unlikely that the Ukrainian counter offensive will play into any Russian meat grinder theory. The Ukrainians could goon it up, but the allies training them will train them to use those weapons with speed and effect.
