I was wondering what the process of cross commissioning is like, or if it's even still possible. Most of the posts I've seen are older and links don't take you to the same pages anymore. Any updated advice on the subject would be appreciated. I.E going AROTC and commission Navy what it might...

Is it possible for a midshipman to participate in sea-year or at least part of sea-year aboard a U.S. Coast Guard vessel? I have heard that it is possible to do so with the U.S. Navy, so perhaps it is possible with the Coast Guard? How might this work either way?
