My personal theory is, that the German entity tasked with procurement has no idea how international commerce works.

I saw a intriguing change in conversations I had over the last couple of days. First it was, like, no need, we got this. Just yesterday I found a call for an offer from the Armed Forces procurement department in my Inbox, while you now find direct contact details for these kind of things online. Not sure what happened, but there sure is a change in how authorities are approaching this.
