Удел человеческий 2 (1959)

This intense war film follows Kaji, a member of Japan's Red Army, as he confronts the brutal realities of military life. Increasingly disheartened by the abuse he witnesses from other soldiers, Kaji is pushed to defend a fellow recruit, Obara, from injustice. His path changes when he encounters his friend Shinjô Ittôhei, who has defected to the Russian side. Caught between the two armies, Kaji is forced into a desperate battle against a powerful Russian tank division. The film is a raw look at war, friendship, and challenging expectations in the midst of conflict.
