Detention of pay shall be for a stated period of not more than one (1) year but if the offender's term of service expires earlier, the detention shall terminate upon that expiration. No two (2) or more of the punishments of arrest in quarters, correctional custody, extra duties and restriction may be combined to run consecutively in the maximum amount imposable for each. Whenever any of those punishments are combined to run consecutively, there must be an apportionment. For the purpose of this subsection, "correctional custody" is the physical restraint of a person during nonduty hours and may include extra duties, fatigue duties or hard labor. If practicable, correctional custody will not be served in immediate association with persons awaiting trial or held in confinement pursuant to trial by court-martial.
When mitigating (a) arrest in quarters or restriction, or (b) extra duties to restriction, the mitigated punishment shall not be for a greater period than the punishment mitigated.
When mitigating reduction in grade to a fine and/or detention of pay, the amount of the fine and/or detention shall not be greater than the amount that could have been imposed initially under this section by the officer who imposed the punishment mitigated.
