Trolls & bots fail to understand or accept that Russia is anything but infinite and inevitable - but numbers are numbers. They’ve spent half of their entire Soviet inheritance to steal what they sit on today. The war doesn’t end when they get to zero vehicles. The half they’ve squandered is surely the BETTER half, and they still need an army for territorial defense and internal repression. Ukraine is not about the break, and this is probably the best position Russia is ever going to be in. This is the endgame of this messy, abusive Divorce, and Pootz has to come up with some whopper lies to say it was all worthwhile.
Russia will likely have more time than we expect. North Korea are proving to be more helpful than expected and have tons of old Soviet era hardware that they would be willing to sell in exchange for some more rocket tech or nuke stuff.
China would also likely be selling their old Soviet era hardware they might still have kicking around. A lot of countries around the world see Putin as desperate and rich so they will be happy to make some money selling older hardware back to the country that made it. Putin likely sees this as fine since the hardware works with the existing forces.
But the money and favors aren’t infinite. Putin is still dying of old age and disease. It’s a long road but Ukraine is destined to succeed.
The Russia won’t run out of military equipment anytime soon. The most important reason to destroy it is that it’s expensive to replace. And when it comes to air defence radars, also not really all that possible to replace.
What brings the war to end is economy. The Russia’s economy won’t survive very long anymore, and once the state is bankrupt, it no longer can pay the high salaries to its soldiers. Since the soldiers are in it almost exclusively for the money, that will mean there will no longer be new soldiers to replace the losses.
The Russia can of course print more money, but that will cause inflation, meaning that the soldiers’ salaries need to be raised more, which increases the need to print more money, which… :)
According to Wikipedia the Soviet era tanks NK has is a few thousand T-55s and some T-62Ms. The T-62 varients are likely good enough to use on the battlefield, but the T-55s may not even be worth the fuel it takes to transport them. Remember Russia was fielding some T-55s not by using them as tanks, but by filling them with explosives and sending them uncrewed against Ukainian lines as bombs-with-tracks.
NK also has a bunch of 60 and 70s era Chinese tanks, but China may object to actual Chinese military hardware fighting in Ukraine.

Russia have lost hundreds of T-62s in this war already but barely any T-54/55s, so it seems that Russia agrees that fielding the older ones isn’t worthwhile. Or 55s are magically invincible, of course, but I know which version I think is more likely
