Ill. Admin. Code tit. 95, § 400.1220
a) General. Whether to impose punishment, and the amount and nature of the punishment, are the sole decisions of the imposing commander. However, the commander is encouraged to discuss appropriate punishments with his or her Staff Judge Advocate after the SMF member has had an opportunity to present matters in defense, mitigation or extenuation. Commanders are also encouraged to consult with their NCOs and other subordinates on the appropriate type, duration and limits of punishment to be imposed. Additionally, as NCOs are often in the best position to observe a member undergoing punishment, and to evaluate performance and attitude, their views on clemency should be given careful consideration.
b) Rules for Imposing Punishment. Unsuspended reduction in grade and forfeitures of pay are effective on the date of imposition, which is the date item 4 of the NGIL Form 60-R is signed by the imposing commander. All other unsuspended punishments take effect immediately upon notification to the member, unless otherwise stated by the commander in item 4. In this regard, the commander cannot choose a date earlier than the date he or she signed that item, but he or she may delay the punishment for legitimate reasons (e.g., the member is hospitalized or on authorized emergency leave). In those cases, the execution of the punishment should begin immediately after the cause of the delay has abated. Also, if a member to be punished is currently undergoing a punishment involving restriction or extra duties under a prior NJP action, the commander can prescribe an additional punishment of restriction or extra duties to begin after the completion of the earlier punishment. Maximum punishments are prescribed in Appendix A.
2) Extra Duties. Extra duties may be required to be performed at any time and, within the duration of the punishment, for any length of time. However, when extra duties are performed during IDT periods, one day of extra duty shall be counted against each unit training assembly for that day. Extra duties may include the performance of fatigue duty or of any other military duty; however, no extra duty may be imposed that:
