USE OF MILITARY SERVICE CREDIT

(a) The retirement system shall use military service credit in computing occupational disability retirement benefits and death benefits and in determining eligibility to select an optional death benefit plan. (b) The retirement system shall use military service credit in computing service retirement or nonoccupational disability retirement benefits of a member of the employee class only if the member has, without military service credit, at least five years of service credit in that class. (c) The retirement system shall use military service credit in computing service retirement or nonoccupational disability retirement benefits of a member of the elected class: (1) only if the member has, without military service credit, at least six years of service credit in that class, if the military service credit was established before January 1, 1978; or (2) only if the member has enough service credit, exclusive of the military service credit, to be eligible for service retirement benefits at age 60, if the military service credit was established on or after January 1, 1978. (d) The board of trustees by rule may permit a person who retires with at least 10 years of service credit, excluding military service credit, to receive service retirement benefits as an elected officer for the percentage of the person's military service credit, but not more than 100 percent, that is derived by dividing the number of months served as an elected officer by 96 months.
