"Vesti" in the article under the heading "The British edition of The Times reported shocking losses of the Armed Forces of Ukraine" tells :
“According to The Times, the Armed Forces of Ukraine are suffering such heavy combat losses that it shocks Ukrainian doctors, as well as NATO instructors.
The Alliance has never seen this before. The British publication notes that the nature of the injuries is severe, and doctors have to make a choice all the time - who will live and who will die, Rossiya 24 reports.
In fact, The Times article is titled "Putin's troops in Donbass will reach a stalemate, Kiev claims" and it says :
“President Zelenskiy said on Sunday that his soldiers are killing hundreds of Wagner fighters every day as they try to outflank the city while launching a frontal attack. “In less than a week, starting from March 6, in the Bakhmut direction alone, we managed to destroy more than 1,100 enemy soldiers, an irretrievable loss of Russia, right there, near Bakhmut,” Zelensky said in a video message. He added that 1,500 Russian soldiers were so wounded that they could not fight.
However, Ukrainian forces are also suffering heavy losses. Russia said on Sunday that its forces had killed more than 220 Ukrainian soldiers in the previous 24 hours. None of these figures can be independently verified."
So the British newspaper did not report "shocking UAF losses", it just told what both sides claim about the losses of the enemy, and at the same time emphasized that their information could not be verified.
As for the “shocked NATO doctors and instructors,” apparently, this is how Vesti interprets another article in the same newspaper, entitled “Ukrainian front-line doctors daily face a choice of who lives and who dies.” It says :
“Every Ukrainian soldier understands that he or she will receive proper treatment, so they are ready to take action at the risk of their lives. This keeps morale high and the soldiers are ready for hard fighting,” said Lieutenant Colonel Indrek Olveti of the Estonian 1st Brigade, 1st Division, who participated in NATO medical training for Ukrainian soldiers ahead of Russia’s invasion last year.
Despite a constant struggle to get enough medical supplies, a lack of modern operating equipment, and Russian shelling of hospitals, half of those rescued will eventually be able to return to active duty in some form. On all fronts, superior Ukrainian medical care could save nine times as many wounded as Russians, according to figures circulated among NATO allies.
In some of the most intense battles in Bakhmut and Vugledar, the ratio of wounded and killed Russians reached 1:1. “Ukrainians are doing 100 percent better,” Lt. Col. Olveti told The Times. “They have their own issues, but they understand the importance of having a pre-evacuation plan and use NATO standards for advanced trauma care. For a Russian soldier, if you get injured, that's your problem - how to deal with it and how to evacuate.
The Russians use old Soviet arterial clamps that are completely ineffective, they have a registered nurse at the battalion level instead of a qualified doctor like in NATO, and their recovery centers are farther from the front line, only at the level of a division or an army corps. When the wounded get there, who have been given these sphincter, you have to deal with amputation, and not with real recovery after the injury.
