If true, that's a huge jump escalation-wise. First thing it tells me is that things must be really catastrophic for the Ukrainians on the ground, second, it really worries me that these idiots will push Russia to using The Mushroom...
Given that Ukraine already spamming cluster lepestok and other form of cluster munitions since very start of the war. ATACMS and cluster is not really escalation i think. It will escalate the difficulty Russian have on the field but to make them use nukes.. No.
The real deal would probably be direct NATO intervention or NATO blockade of Russian ports in Black Sea and elsewhere.
These articles says that a recent press release that Rostec is suspending secondary UVZ contracts and focusing only on producing tanks.
Russian tank production rate has been claimed by the Russian security council to have increased to 120 tanks a month (~1500 tanks fiscal 2023), which is 3.5 times the maximum rate in peacetime. (350-400)
I'm more curious on whether these tanks are new built. like started from pure raw material instead of drawing from storage and modernize them. The Turret however esp for the T-90's be it A or M it will always be new as it's welded construction instead of cast turret like in old T-72 and T-80's. The hull however i wonder.
