Neubaufahrzeug tanks in Oslo, 1940. The Neubaufahrzeug was an experiment in heavy tank production and was utilized more for propaganda purposes than actual combat. However, the three NbFzs seen above particiapted in the Battle of Norway, near the small town of Balberg at the far south end of the Gudbrand Valley. The British Expeditionary Force was equipped with 0.55 inch calibre Boys Anti-tank rifles that easily penetrated the NbFz. After dozens of hits, including one that killed a crew member, the tank retreated and the crew was hesitant to advance further. Other German units pushed further through, flanking the British forces and forcing them to retreat.
According to contemporary German sources, three NbFz were attached to the 1st Panzer Army and destroyed in battle with Soviet BT-7 tanks in present-day Ukraine in June 1941.
