Secretary  concerned,  a  commanding  officer exercising general court-martial jurisdiction or an officer of general or flag rank in command may delegate his powers under this article to a principal assistant. (b)   S u b j e c t   t o   s u b s e c t i o n   ( a )   a n y commanding officer may, in addition to or in lieu of admonition or reprimand, impose one or more of the following disciplinary punishments for minor offenses without the intervention of a court-martial… Commanding officer’s nonjudicial punishment is often referred to as captain’s mast. Captain’s mast gets its name from the old sailing days when the setting for this form of naval justice was the weather deck near the ship’s mainmast. Cases are heard and punishments given at captain’s mast. Anyone who is not attached to or embarked in a vessel may, however, demand trial by court-martial in lieu of punishment at mast, before such punishment is imposed. The  punishments  permitted  at  captain’s  mast depend upon the rank of the officer holding mast. Figure 2-3 shows the punishment that may be awarded. A  commanding  officer  that  decides  an  offense deserves  a  punishment  more  severe  than  he/she  is authorized to award at mast may order a court-martial. The  following  paragraphs  explain  some  of  the punishments that may be given at captain’s mast. RESTRICTION.—Restriction is the requirement to remain within certain specified limits (ship, station, etc.). Although required to muster at certain times, the restricted person usually continues to perform his/her regular duties. CORRECTIONAL  CUSTODY.—Correctional custody  is  the  physical  restraint  (confinement)  of  a person  during  duty  or  nonduty  hours,  or  both.  The person may be required to perform extra duties or hard labor. A typical example is an individual who is free to carry out regular duties during the day but is confined in a confinement facility at night. 2-37 Student Notes: ENLISTED Any officer commanding, LCDR and above Commanding officers below LCDR; OICs, any grade Admonition or reprimand Yes Yes Confinement on B&W or diminished rations 3 consecutive days (aboard ship) E-3 and below 3 consecutive days (aboard ship) E-3 and below Correctional custody 30 consecutive days E-3 and below 7 consecutive days Forfeiture of pay 1/ 2 of 1 month pay per month for 2 months 7 days’ pay Reduction in grade To next inferior grade To next inferior grade Extra duty 45 consecutive days 14 consecutive days Restriction 60 consecutive days 14 consecutive days Figure 2-3.—One or more of the maximum punishment authorized by article 15,  UCMJ.
