10 U.S.C. § 12731b

(a) In the case of a member of the Selected Reserve of a reserve component who no longer meets the qualifications for membership in the Selected Reserve solely because the member is unfit because of physical disability, the Secretary concerned may, for purposes of section 12731 of this title , determine to treat the member as having met the service requirements of subsection (a)(2) of that section and provide the member with the notification required by subsection (d) of that section if the member has completed at least 15, and less than 20, years of service computed under section 12732 of this title . (b) Notification under subsection (a) may not be made if— (1) the disability was the result of the member’s intentional misconduct, willful neglect, or willful failure to comply with standards and qualifications for retention established by the Secretary concerned; or (2) the disability was incurred during a period of unauthorized absence.
