Your stating of Russian death figures shows all I need to see. Who knows about Ukrainian deaths…. You could be right, 30-50 russian, maybe in bakmut or adiivka, but for two years with their human wave tactics. Not buying it.
Ukraine info on Russian losses, on the other hand, is pure bullchit used to keep the public misinformed about the battlefield situation, and to keep Western aid flowing based on Ukd claims of success.
Choose your sauce.
