During the Winter War, the amount of Soviet Union soliders that died or went missing was five times more than Finland's.

During the Winter War, the Soviet Union suffered significantly higher casualties compared to Finland, with approximately five times more soldiers reported dead or missing. This discrepancy can be attributed to a combination of factors. Firstly, the Finnish Army possessed a strong defensive position and benefited from the harsh winter conditions, which they were accustomed to and used to their advantage. Additionally, the Finnish forces had superior marksmanship skills and were able to effectively execute guerrilla tactics against the larger and more technologically advanced Soviet Army. Furthermore, the Soviet Union faced challenges in terms of leadership and coordination, as their initial invasion plan was hastily prepared and lacked proper strategy and logistics. These factors culminated in a higher casualty rate for the Soviet Union during the Winter War, ultimately resulting in their failure to achieve a swift victory.
