The Soviet Volunteer Group was the volunteer part of the Soviet Air Forces sent to support the Republic of China during the Second Sino-Japanese War between 1937 and 1941. After the Marco Polo Bridge Incident, the Sino-Soviet Non-Aggression Pact was signed leading to considerable Soviet military assistance to China, including the volunteer squadrons. China paid for the support with raw materials.
