4 Ka-52s lost so far, well below their replacement rate.
Also, Oryx's list is incomplete, has known errors, and means nothing, which was pointed out pages ago. If we grant 100% accuracy to his lists, Russia could easily afford 5 to 1 losses and come out ahead, that and as the Russian MoD releases more video evidence, it is becoming clear the UkA has lost more men and vehicles than Russia has. Kherson Base alone was a Brigade Base containing Divisional Assets and was overran pretty quickly with its vehicles and ammo captured and its Garrison basically disintegrating. Also a good 70,000 of the UkA's troops are trapped in pockets, 10,000 alone in Mariupol. As those close, Russia will be getting the bulk of their gear back and UkA will be losing the bulk of its professional troops.
Finally, Ukraine is throwing teenagers on the front with just 3 days training and is short on rifles and ammunition. Russian Recruits are being sent in with a minimum of 6 months training. Also the Foreign Legion got wiped, and Ukraine's ability to make and distribute war material is being systematically destroyed.
More reinforcements. Putin is making it clear that he will have victory. A clear and decisive one.
