How will my first PCS work?

What's you actual question?

No different than any other change of station, just with family attached there are additional steps involved ie household shipping, etc.

Attend the briefings that are involved as they will explain most if not all of what is involved. If you still have questions get in touch with your command to handle additional details. Pay attention to what you are told and make sure your family is aware as well.

Attend a Levy brief, they explain majority of what will need to happen and how things go. But you can expect a lot of running around getting everything scheduled and cleared.
