The Berliet GDR series was designed for a payload of 5 to 7.5 tons. This formerly civilian lorry is a Berliet GDR for a payload of 5 tons. Note the different bumper compared to the Berliet GDRA.
This Berliet lorry is most probably a GDR, too. By the look of the driver’s cab, it is an older vehicle of this series. The photo was made in Finland.
