In the 3-ton (or medium) of transport trucks the major and most successful design was the Opel Blitz. This was a 1938 design from Opel (the German subsidiary then, as now, of General Motors) and was quite conventional in layout. The Opel Model S3.6-36, to give its maker’s designation, was a 4×2 vehicle with pressed steel cab and bonnet. Suspension was by conventional leaf springs. During its war production run, there were many special purpose variants produced; over 100 different types were recorded.
