A person who is an honorably discharged veteran of the United States armed forces, a member of the Tennessee national guard, a member of the Tennessee air national guard, or an inactive reservist of any of the United States uniformed military services in good standing must not be disqualified as a candidate for any office if, for service-related reasons, that person was unable to comply with a statewide political party's or recognized minor party's rules for candidacy for nomination for such party, and such service-related reasons are the sole reason the person is unable to qualify.
