During their first night in the bunker, when Kreuzmann is expressing his worries to Ebert about an American attack and the bunker being "not quite right," at the end of the conversation he says "God with us." Aside from being an obvious religious statement, it also refers to the saying that was inscribed on Germany Army belt buckles: "Gott mit uns" or "God with us." This was also common inscription on armour in the German military until the end of the Third Reich, and has a history and usage in Germany dating back as far as the Teutonic Order.
