Honestly, this is really good. I'm almost considering giving it a 5. While I don't think the concept is terribly interesting, it is original, and executed extremely well.
I had my doubts about the "giving an RPC to a GOI" idea at the beginning, but the log at the end does make sense. I don't have any major criticisms with this article at all, but I do recommend you read it over, because I spotted a couple of spelling mistakes, the usage of "sure as hell" in what I assume is supposed to be translated text doesn't sit right with me.
If it were me, I'd also recommend making the German Anomalous Research Division Anomalous Threat Report a bit longer, considering they'd probably want their soldiers to know about this thing, and I'd probably take out the picture of just some random SMG that's in there.
Maybe I just haven't read too many SCPs, this was refreshingly well written. Splendid work.
