Commissar Danilov (died 1943) was a Soviet Red Army commissar who served in World War II. He fought at the Battle of Stalingrad, where he befriended the Soviet sniper Vasily Zaitsev after Zaitsev helped rescue him from a massacre at the city's Red Square. Danilov wrote glowing reports of Zaitsev's exploits in the army's magazine, but the relationship between the two men soon soured over their shared romantic interest in the Russian sniper Tania Chernova, causing Danilov to disparage Zaitsev in a letter to his superiors. However, after Chernova was believed dead from a shrapnel wound, Danilov grew remorseful for his jealousy, as well as disillusioned with communism, and he decided to help his friend Zaitsev one last time by exposing himself to the sniping fire of the German soldier Erwin Konig, who shot Danilov and, in doing so, revealed his position to Zaitsev, who shot him.
