Panserkanon 44

The Panserkanon 44 was a family of armored fighting vehicles, primarily Self Propelled Gun carriers developed to provide a mobile fire support platform and Tank Destroyer to the recently expanded armored forces of the Ringerike Army, the Pk.44A was originally intended to function more as an assault gun than self propelled artillery, but this decision was reversed not long after it's entry into service, which lead to the development of the Pk.44B, which remained in widespread use by the Ringerike Army until it's withdrawal starting in 1967.
