Why did russia lose so many in World War 2?

Russia, or the Soviet Union, suffered immense losses during World War II due to several factors. The initial surprise of the German invasion in 1941 caught the Red Army unprepared, leading to significant casualties and territory loss. Additionally, the brutal tactics employed by the Nazis, including mass executions and scorched earth policies, exacerbated the human toll. The harsh conditions of the Eastern Front, combined with inadequate supplies and logistics, further contributed to the staggering number of Soviet casualties.
