According to whom and compared to what? Russia has employed maybe 20% of their military personnel and gear and are weeks, maybe days, from consolidating and absorbing the Donboss.
Keep in mind that Ukraine is the second largest military in Europe (after Russia) with their own military industrial complex, huge cache of Soviet weapons and the training and intelligence assets of NATO.
Can you name a single successful significant counter offensive (other than the Moskva) by Ukraine?
It is hilarious, if only it wasn’t so sad.
That is a shallow measure. Most modern armies have "tooth to tail" [0] ratio less than 1:5. Combat-ready units constitute a minority of the entire military personnel everywhere, and Russia has deployed most of those in Ukraine. It cannot afford to deploy all of them, as it has long borders and shores that need patrolling.
Russia no doubt has a huge cache of Soviet-era weapons, but it has already burnt through much of that cache, much like Ukraine did. Given that they are transferring T-62 to the theater, deploying ancient Kh-22 missiles and that the dud rate for both missiles and artillery shells seems to be between 10-30 per cent, it seems that they are already down to using older, less reliable stock. That does not mean that they ran out of modern stuff completely, but rather that the newer stock is depleted enough that they need to be careful about that.
For me, the humiliation consists of the current stalemate. I don't require any massive counteroffensives from the Ukrainians to see the Russian advance as a failure. They didn't manage to take freaking Kharkiv that lies just 40 km from the border and they fought three months over Mariupol, besieged from all sides.
This is just incompatible with the image of an unstoppable bear that Russia cultivated before the war.
As for the (retrofitted) T-62s, those are mostly given to the Donboss militias and a perfect tank to use in the already conquered rear. They are still armor and they still function. US also runs some old gear if you didn't know.
As for the dud rates, I'd expect that for older missiles. Their new stuff (which is more advanced than anything the US has) is less than 10%. And it's clear they're not running out any time soon despite western media claims two months ago that their weapons stocks were days from depletion.
On the other hand, the dud rate for western supplied Javalins and NLAWs is around 80% as reported by Ukrainian military personnel. And it's actually now illegal for Ukrainian troops to publicly criticize the effectiveness of western supplied weapons.
Let's stop projecting and be honest about what's actually going on.
They do still have their artillery, though, and they are trying to take Donbass. In a very piecemeal fashion, very slowly. They have learnt something from their spring failures.
The result of this war depends on how fast can the Ukrainians re-arm completely to Western weapons, including artillery. It does not make sense to send tons of heavy Western guns there, if there aren't enough trained soldiers to operate them and enough trained technicians to fix them.
This is the bottleneck, not the raw number of weapons; people tend to treat weapons as magic, but they only work in combination with skilled soldiers and a functioning supply chain.
The Ukrainians are learning fast - people generally learn fast when their country is on fire - but the process will likely take months.
