The story
The GAZ-55 (Russian: ГАЗ-55) was a Soviet military ambulance developed in the 1930s by Gorkovsky Avtomobilny Zavod (GAZ) and was used by the USSR during the Second World War. It was based on the GAZ-AA model. With only 9,130 models ever produced, the Red Army still relied heavily on standard trucks to transport their wounded. Production of this ambulance reportedly continued until 1946. At least one GAZ-55 was captured by a unit of the Luftwaffe.
