In Starship Troopers, federal service is always voluntary and never compulsory. The logic behind this being that a society that can't depend upon volunteers for its own defense does not deserve to survive. If a person signs up for federal service, they can quit at any time. But if they quit before their term is up, they don't get the right to vote and they are never allowed to sign up for federal service again.
Israel also has mandatory service with the option of military or civil service if I remember correctly.

U very smart on starship troopers.
I've always meant to read the book but never got around to it, unfortunately.
It's one of my favorite sci-fi novels. I've read it several times over the years.
