I don't know, Grilo...but the first hit on that search I led you to revealed pretty much the information you were looking for. It would be worth your while to at least peruse the Navy forums. I can't help but get the impression that you don't want to read through the numerous threads on the subject, and just want to go right to specifics. If that's the case, then I don't know why you didn't just pose specific questions.
Of course, plying a neighbourhood MARS officer with alcohol works too.
