Here's the Springer demolition vehicle from the same set. Again, it lacked a driver, so I added one myself.
The Springer was based on the Kettenkrad tracked chassis with an extra set of road wheels and lacking the front forks, and carried a demolition charge of 330kg. It was driven near to its target, and then the driver dismounted and it was guided on to the target and detonated, either by wire or by radio control. It was, naturally, pretty dangerous for the driver-controller.
It was a single-use device, and was really too complex and expensive to be justified; only about 50 were made.
