After her father died in early 1942, Yulia went to Khabarovsk, in the Russian Far East, where she enrolled in a school for aviation technicians but, wanting to fight on the frontlines, she soon joined a rifle unit as a combat medic and was sent to the Belorussian Front, where she served alongside Zinaida Samsonova (also a combat medic), who in 1944 died in combat and was posthumously awarded the title of the Hero of the Soviet Union.
