Putin killed those soldiers for his ego

27:1 kd would be accused of cheating in video games.

Because this stat isn't really a stat and isn't hyped or published, I'm going by DDG AI assist which suggests US k:d in Iraq is 44:1

The U.S. military suffered approximately 4,492 deaths and around 32,292 wounded during the Iraq War, while estimates suggest around 200,000 Iraqi civilians were killed. This results in a rough kill-to-death ratio of about 44:1, favoring U.S. forces, though this does not account for all combatants and the complexities of the conflict.

Considering that Ukraine isn't killing civilians... Classic AI bullshit uselessness.
If I killed 27 enemy aggressors while defending my country, I would die happy. I don't ever want to be in that position, I don't think anyone should ever be in that position. But that is an achievement, under the circumstances, to be proud of

According to duckduckgo, Russia has ~4x the population of Ukraine.

Supposedly the kill ratio at Pokrovsk has been around 15:1 as well.

If that's the average, I feel really bad for the high end outliers...

Rookie numbers. They can do better than that! Hustle guys and gals! I’d like to see that number tripled the next time those idiots try and take shit that isn’t theirs.
