During World War II, the Soviet Union's troops sustained the greatest number of deaths compared to any other country involved in the conflict. The exact number of Soviet military casualties is difficult to determine, but estimates range from 8 to 10 million soldiers who lost their lives during the war.

The Soviet Union's high casualty rate can be attributed to the brutal nature of the Eastern Front, where the majority of Soviet military engagements took place. The Eastern Front was characterized by large-scale battles, harsh weather conditions, and ruthless tactics employed by both the Axis and Soviet forces. The Soviet Union's willingness to sacrifice large numbers of troops in order to achieve victory also contributed to their high casualty rate.

In addition to military casualties, the Soviet Union also experienced a significant number of civilian deaths during World War II. The German invasion of the Soviet Union in 1941 led to widespread destruction and loss of life, particularly in cities like Stalingrad and Leningrad.

Despite the staggering number of casualties suffered by the Soviet Union, their contribution to the Allied victory in World War II cannot be understated. The Soviet Union played a crucial role in defeating Nazi Germany on the Eastern Front and ultimately turning the tide of the war in favor of the Allies.

Their resilience and determination in the face of overwhelming odds helped secure victory for the Allies and shape the course of history.
