In my personal case, when I reported the incidents that happened to me, on the police reports that they made, where it said who the victim was, all it said was female aviator and my unit. It was confidential in that sense, because that was the same report that the CDS and the commander of the air force read. They had no idea who I was, but in a local sense of who I knew read it, it was not hard to figure out. Because I am in a male-dominated trade, it was not hard to figure out who the female aviator was from my unit.
That's the only thing that I think, confidentiality-wise, could be improved, but any ideas I have about that are quite slim.
