Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
The Joint-Military Exercise continued in various mock battles over the course of three weeks. Before Bruno was invited to the Hofburg once more, which was the primary palace of the Habsburg Dynasty. Overall, there was quite a bit that Austro-Hungary learned from their German counterparts.
And during the dinner that followed the event, Bruno brought up many ideas that could be used to improve Austro-Hungarian performance in the field. And while his ideas certainly made sense, there were political, economic, and industrial challenges that needed to be faced to fully implement them.
Meaning that Bruno ultimately did not pursue them any further than mere lip service. Fundamentally, whether or not Austro-Hungary actually performed respectably in the war wasn't important to Bruno.
