This number includes 1,096 casualties Russian forces suffered just over the past day, the General Staff of Ukraine's Armed Forces reported on April 28.
Out of the half a million troops killed I wonder how many were actually Russians? Doesn't look like things are working out for them.
That number doesn't mean KIA. That encompasses all casualties. So if you got arms and legs blown off and can no longer fight, you are lumped into that number. The KIA number is around 130-140k. Which is still a lot of people.
In context of the war, this number is more relevant. Dead or too injured to fight, fewer troops are fewer troops. It doesn't really matter what percentage in that 466,150 number are still alive when it comes to Russia's chances against the Ukrainian military.
It's worth remembering that WW2 was an existential threat to the Soviet Union and most of the people living in it. This war isn't. See how the Soviet invasion of Afghanistan turned out.
And, of course, Ukraine was also part of the Soviet Union. Russians weren't the only ones fighting the Nazis on the Eastern Front
Russia apparently has a deep history of spending enormous numbers of lives for military victories. Unless something changed I wouldn't rely on casualty numbers to indicate if they are close to breaking.
