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.
Whether they have run ‘out’ is moot. They’ve squandered their BEST, at any rate, and aren’t bothering to use what remains, and that’s kind of the point. Saying that it’s ‘half gone’ is the same as saying it’s ALL gone in the context of trying to conquer ukraine. You have to keep a fleet available for credible border defense, future offensive operations (which are now probably off the books) and internal oppression of your own population. And as you say - both in terms of armor and artillery - even if you have remaining stockpiles, you can’t sustain this burn rate, and each piece you move forward is less effective that the one it replaced, both in terms of age, utility and the caliber of who’s left operating it.
Capabilties degrade when you piss away your army in a sunk cost fallacy revenge project.
