[Starship Troopers] So the line for recruiting was "Service Guarantees Citizenship". What are other folks classified as before they're 'citizens'? What are their rights?

The term *citizen* stands in contrast to a *civilian*.  Citizenship grants you the right to run for office and vote.  And (according to the book) thats it.  

That might seem to be... not much.  But the perspective taught to Rico in school is that no one will value the right to vote if it is given freely.  By forcing the vote to have a price in time spent in public service, the citizens will take their franchise seriously and vote seriously.

I believe in the movie universe, they also added cheaper education and the ability to have more children.
