Detention of pay shall be for a stated period of not more than one year but if the offender’s term of service expires earlier, the detention shall terminate upon that expiration. No two or more of the punishments of arrest in quarters, confinement, 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. In addition, forfeiture of pay may not be combined with detention of pay without an apportionment. For the purposes of this subsection, “correctional custody” is the physical restraint of a person during duty or 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.
