During World War II, the Wehrmacht used three remotely operated demolition tanks: the light Goliath (Sd.Kfz.

During the Battle of France, German engineers from the 1st Panzer Division converted 10 Panzer I Ausf Bs into demolition and mine clearing vehicles, using them to place timed charges on bunkers or minefields without losing the vehicle.

The Waffenamt found the idea valuable, and ordered the B IV's development as a remote-controlled demolition vehicle.

When it reached the target, the vehicle would drop the charge and leave the danger area.

C was thicker than the previous variants, new tracks were used, the driver's seat was moved to the left of the vehicle and a new 78 horsepower six-cylinder engine was used.

Bs and Cs were converted to the Panzerjäger Wanze, armed with six RPzB 54/1 anti-tank rockets.

In the last days of the war, these vehicles fought some minor skirmishes against Soviet armor and saw some action at the Battle of Berlin.

B was rebuilt as an amphibious vehicle, and in 1943 one Borgward IV was equipped with a television camera for observation.

Like Germany's other remote-controlled demolition vehicles, the Borgward IV was not considered a success; it was unreliable and expensive, although unlike the Goliath and Springer it could be used multiple times.

On 31 March 2010, demolition work and excavation at Wien Südbahnhof uncovered a relatively well-preserved Borgward IV along with other relics from the Vienna Offensive.
