Where is air superiority? Non-existent.

Did you somehow miss all the videos of Russian aviation taking out tanks on daily basis, or the fact that Russia does massive air strike campaigns against entire Ukraine weekly for many months now? Meanwhile, Ukraine has no air force to speak of, and at this point doesn't even have much of air defence. What you're saying is demonstrably false.

Where are the huge tank battles?

There aren't huge tank battles because Russia is letting Ukraine blow up all their tanks in minefields and hunts them down with lancets. The battles we've seen so far are Ukrainian columns following a single mine clearing vehicle that gets taken out by a helicopter or artillery. Then the column ends up being stuck because it's in a minefield, and the rest of the vehicles are systematically destroyed. These were the first two weeks of the offensive after which Ukraine abandoned the fabled NATO tactics and went back to sending penny packets of troops to get ground down by artillery.

I am amazed that someone can still believe in the Russian military when despite overwhelming numbers, Russia has not been able to defend itself against its neighbor, 1/5th its size and certainly less prepared for war.

That's because you have absolutely no clue regarding the subject you're opining on. Here's what an actual expert has to say https://www.russiamatters.org/analysis/whats-ahead-war-ukraine

You think it’s a sign of victory that Russia is now using WW2 era tanks they are pulling out of storage?

What this actually shows is that Russia doesn't even feel the need to pull out its modern equipment, they're clearing out their old inventory the exact same way NATO is.

NATO is not running out of stock, it is simply getting rid of old inventory and ramping up production on new munitions.

Biden literally admitted that US ran out of high explosive shells to send. This is also admitted by mainstream media. Meanwhile, this is what the "dramatic increase in production actually looks like:

Army Secretary Christine Wormuth separately told reporters that the U.S. will go from making 14,000 155mm shells each month to 20,000 by the spring and 40,000 by 2025.

That's what Russia uses on daily basis, and Russia produces over a million shells a year

You really should spend a bit of time educating yourself instead of spreading misinformation here.
