y 1934 there were four base versions offered of the 1 tonne basic model along with fourteen versions of the larger 2 and 2½ tonne trucks. Under the terms of Nazi economy and the German re-armament the authorities ordered the construction of the Opelwerk Brandenburg facilities in 1935, where until 1944 more than 130,000 Blitz trucks and chassis were produced.

From 1939, the reliable Blitz 3.6 three-ton version was used in large numbers by the German Wehrmacht armed forces throughout World War II. Derived variants included an elongated version and the four-wheel drive Blitz A. To cope with the bad road conditions and the rasputitsa mud seasons on the Eastern Front, a half-tracked Maultier (mule) Sd.Kfz. 3 version was built using tracks and suspension based on the Universal Carrier. Among others, these were used as service vehicles for the Messerschmitt Me 323 military transport aircraft. It is also claimed that Opel, a subsidiary of GM, used forced labor to reap unprecedented profits.[2] To what degree GM controlled Opel at the time is subject to debate, but it is clear that GM did in fact play a role in giving Nazi Germany the Opel Blitz truck.[3]
