Serving in the military is the right of any citizen
technically (in the interests of fairness) I can't be (and wasn't) allowed to serve on account of my CP. the military can screen for individuals deemed unable to serve due to particular physical or psychological impediments. it's one of the few lines of government work that's allowed to eliminate applicants in such a way - for reasons that should be pretty obvious. this is another case where right and privilege are being semantically conflated one with another. it's a really minor distinction, but I thought it'd be helpful to point that out.
