This is an injection-plastic military vehicle model kit.
From the manufacturer description:
The FWD model B 3-ton Lorry was an American truck of the World War I period, created by the Four Wheel Drive Auto Company in 1912. Like all machines of that time, it had quite a primitive design, but one particular innovation (the engine over the frame and the driver's cabin shifted forward) revolutionized the automotive industry. The FWD Model B was widely used in World War I. Of the total of 17,555 built, the vast majority (14,473) went to the U.S. Army, while another 3,000 were sold to Great Britain, and 82 units were bought by Imperial Russia. The last surviving machines of this type were used in the early 1940s.
