While the majority of Sd.Kfz.8s was built as artillery tractors some were converted for other uses, the most notable were the ten 8.8 cm Flak 18 (Sfl.) auf Zugkraftwagen 12t (Sd.Kfz. 8) vehicles with modified 8.8 cm Flak 18 anti-aircraft guns mounted on rear pedestals, all these were all built on the DB s8 and DB 9 chassis. These vehicles were used by Panzerjäger-Abteilung 8 during the invasion of Poland in 1939, the Battle of France in 1940 and Operation Barbarossa in 1941; the last three vehicles had been lost by March 1943.
This vehicle can't be called succesful. Armour was frankly weak, and the general scheme was impractical. Full height of vehicle, with gun shield, was 3225 mm, so that such an important parameter as a "stealth" was not applicable to it.
