If they haven't done it by the time they hit either 2 years to the max age or the max age they get forced to do it, or fined or something. I know people that refuse get fined or maybe even jail I'm not sure, Idols wouldn't because it would be really bad press to do that. It's seen as light a right of passage type thing, so it's not just the government that needs them to do it but their society to. Only way to get out of it is if you have a legitimate health concern, like a member of Koyote signed up to do his service and in his health check up they found out he had a brain tumor so he got exemption from military service.
