20 ILCS 1815/5-15
The Adjutant General may prescribe, by regulation, administrative procedures to involuntarily separate any enlisted member from the State Guard for cause that are similar to those procedures which apply to members of the Illinois National Guard, except that any administrative procedures prescribed by the Adjutant General under this Section shall provide that no enlisted person is entitled to present his or her case to a board of officers unless the enlisted person has at least 6 years of total military service in the State Guard at the time the separation action was initiated. Such administrative procedures shall require the Adjutant General to characterize the enlisted member's service as honorable, general (under honorable conditions), or under other than honorable conditions; however, in no case may the Adjutant General characterize an enlisted member's service as other than honorable unless the enlisted member is afforded the right to present his or her case to a board of officers.
