Particularly affected by difficulties with the suppression of long-term fortifications – these concrete structures, unassailable gun emplacements, often with multiple machine guns and even cannons. From the front to suppress such resistance was virtually impossible to destroy – only after a long artillery bombardment or air bombing. Needed were powerful tools of destruction.
