At the behest of her heart, she firmly decided to go to the front, where the fate of the Motherland was being decided. She served in the Stalingrad front. In difficult moments of life, Second Lieutenant of the medical service Rusanova Olga Andreevna did not think about death. Olga Andreevna recalled: “We were on duty at the operating table for two or three days. We tried not to pay attention to shelling and bombing. I worked not only in the hospital, but also transported the seriously wounded from the besieged Stalingrad to the other bank of the Volga by boat. She was awarded of the medal "For Combat service".
