Because Bundeswehr incompetence. I believe the state of the german military can be explained by considering that after the cold war it was absolutely gutted and never meant to be an efficient armed forces because there was no support for that, not politically and not among the german people. The remains were just meant to be some kind of feel-good alibi towards NATO partners. And it's not even about the money but about how it was setup as an organization. Just compare french and german military spending and military capabilities to get an idea how inefficient the german military is. And then also think about which types of people would make a conscious choice to spend their professional career in that environment and what their motivations are. I don't want to offend anyone but I think it's not far fetched to say that many are in for the comfy low effort paycheck with no intention of actually pulling their weight when it matters. It's absolutely sad and wasteful but at least it seems that finally change is started to improve and to take national defense more serious again. But the necessary changes are immense and will take quite some time. So, saying this as a german citizen, maybe manage your expectations towards the professionalism of the german military at least for a couple more years 🙁
