GAZ-63

The GAZ-63 is a Russian 4x4 2 ton truck produced from 1948 to 1968 at the Gorky Automobile Plant. It was a development of the earlier GAZ-51 truck and is very similar in appearance.

The GAZ-63 was in turn used as the basis for the BTR-40 armoured personnel carrier.

In the parodies
It was the truck with the speakers that was used by Weidling to announce surrender. It also portrayed the Truck of Doom. Considering the film to take place in 1945, but the truck's prototypes was made in 1946, the truck was indeed too new for a WWII film.
