When I was in the Nav the MAAs aboard ship were the worst careerist suck-butts on the crew. I doubt that it has changed. I have no doubt that this case was phonied up from the beginning.
Same aboard both of the vessels I served on. The most petty, conniving, butt-kissers became MAA’s. They were the wussy boys who got picked on when they were kids. I am not kidding.
We used to get rid of those who couldn’t fix planes or any other job by sending them to security. I’m sure it still works the same today.
