"Welcome aboard the Space Station Chesapeake Bay, sailor. It looks like you've picked up some standard weapons skills at basic on Coronado Island. Now it's time for your tour of duty. Your tour will consist of four postings over four years. In this man's Navy you're given a choice of three different postings a year. It's up to you to decide what kind of career you want to have, so choose wisely. Just approach a shuttle bay to receive a briefing on a posting. If you think that posting is right for you, head into that bay to accept the assignment."
