Note: This is from last year. The numbers are much higher now. Ukraine puts the number of dead Russian soldiers at 376,030. The US says it’s 315,000 personnel.
Either way, if those numbers are anywhere close to the trugh, then Russia has already lost ~50% of the personnel that the entire Soviet Union lost in its 9 year-long invasion of Afghanistan. And the fallout of the war in Afghanistan contributed a lot to the fall of the Soviet Union.
