Armored car
Vorpanzer is a term used in fortress construction in the 19th and early 20th centuries.
Since a weak point could not be avoided due to the design of rotatable gun turrets in armored domes at the point of transition from the factory roof to the gun well , the so-called armored armor was used here.
It was a frustoconical, arched steel ring that sat on the edge of the gun well and at the top (in most cases) carried the rotating ring of the gun cupola. It was also covered with a layer of concrete. However, the designers did not succeed in finally eliminating the known weak point in all cases. During the First World War, for example, bombardment with the heaviest calibers ( 30.5 cm and 42 cm ) damaged the armor of several fortresses on the border between Italy and Austria-Hungary on the plateau of the seven municipalities (Altopiano dei Sette Comuni) on both Italian and even on the Austrian side. As a result, the explosion in the gun well not only killed the entire gun crew, but in several cases also threw out the entire tower dome.
