Which army has killed more of its own in war?

Answer 1

Throughout history, the Soviet Union is often cited as having the highest number of its own soldiers killed in wartime due to its actions and policies during World War II, particularly during the Great Purge and the brutal tactics employed in various battles. Estimates suggest that millions of Soviet soldiers died from both combat and execution by their own leadership. Other armies, such as China during the Cultural Revolution and certain regimes during civil wars, have also inflicted significant casualties on their own troops, but the scale of Soviet losses remains particularly notable.
