This is a Dyrenkov 12. The D-12 was a Soviet light armored car based on the GAZ-A automobile and was intended for infantry support and anti-aircraft roles. The D-12 served during the early 1930s and was observed on Red Square during November 7th parades. Some vehicles remained in service during the war in 1941 and a few participated in the victory parade in Mongolia in 1945.
Squint your eyes, and you can imagine a TD hiding inside.
