There were many motor vehicles in the service of the Fil-Am forces on Bataan, probably more than the rough road network could support. Nonetheless the unsung truck played an important role in moving men and materiel. Many were civilian vehicles impressed into military service. There were also newer military vehicles which arrived in the Philippines during the hasty buildup in 1941. Images of these are seen in the prewar photos taken, such as this 1.5 ton truck. Usually identification of such a “normal” object is left at just that, a truck. But even a lowly truck has a pedigree.
In this case, more specifically, these photos are of Chevrolet 1 ½ ton 4×4 G506 series trucks. This closed cab truck was powered by a Chevrolet 235 cubic inch six cylinder engine generating 83 horsepower with a four speed transmission and a two speed transfer case. The wheelbase was 145 inches. It had a standard 9-foot bed which was either made of wood or metal.
The standard truck as seen here (there were many other variations on the basic chassis), is a G7117 which was equipped with a PTO winch at the front bumper. The G7107 (seen below behind jeep) was the same but without the winch. To differentiate, the G7117 can be seen with the fender extended forward a bit, two horns on top for tying chains to and a small roller on the bottom of the bumper.
So for the sake of posterity, we have now identified one of the trucks used by the Fil-Am forces in the Bataan campaign. Certainly there are other military vehicles to be identified from period images, but that is for another day.
