NOTE In  this  section  of  the  chapter,  the  words “he,” “his,” and “him” do not indicate gender and are used for economy of communication. Art. 2. Persons Subject to this Code The  following  persons  are  subject  to  this code: (1)  Members  of  a  regular  component  of the  armed  forces,  including  those  awaiting discharge  after  expiration  of  their  terms  of enlistment;  volunteers  from  the  time  of  their muster  or  acceptance  into  the  armed  forces; inductees  from  the  time  of  their  actual induction  into  the  armed  forces;  and  other persons  lawfully  called  or  ordered  into,  or  to duty in or for training in, the armed forces, from the dates when they are required by the terms of the call or order to obey it. This  article  includes  all  persons  on  active  duty, certain retired persons, prisoners, and prisoners of war. You  should  specifically  note  the  following provisions of article 2: · Any  person  serving  a  sentence  imposed  by  a court-martial  remains  subject  to  the  UCMJ.  Thus  a prisoner who is serving a court-martial sentence may be tried  for  a  crime  committed  while  a  prisoner.  This applies  even  though  the  prisoner’s  term  of  enlistment has expired at the time of commission of the crime. · A reservist on inactive-duty training is subject to the UCMJ when (a) the training is authorized by written orders;  (b)  the  orders  are  voluntarily  accepted  by  the reservist; and (c) the orders specify that the reservist is subject to the UCMJ. · A  reservist  ordered  into  the  active  military service is subject to the UCMJ beginning on the date specified  in  the  orders  for  the  reservist  to  report  for active duty. · The  United  States  Supreme  Court  has  held unconstitutional   the   exercise   of   court-martial jurisdiction over civilians in time of peace. Art. 3. Jurisdiction to Try Certain Personnel Article  3  states  that  a  person  may  be  tried  by court-martial,  even  after  leaving  the  service,  for offenses committed while subject to the UCMJ. Art. 7. Apprehension (a)   Apprehension is the taking of a person into custody. (b)   Any    person    authorized    under regulations  governing  the  armed  forces  to apprehend  persons  subject  to  this  code  or  to trial  thereunder  may  do  so  upon  reasonable belief that an offense has been committed and that the person apprehended committed it. (c)   Commissioned   officers,   warrant officers, petty officers, and noncommissioned officers have authority to quell quarrels, frays, and  disorders  among  persons  subject  to  this code and to apprehend persons subject to this code who take part therein. Enlisted  persons  performing  police  duties  should not apprehend an officer except on specific orders of a commissioned  officer.  The  exception  is  when  such apprehension  is  necessary  to  prevent  disgrace  to  the service,  the  commission  of  a  serious  offense,  or  the escape of one who has committed a serious offense. In such  cases,  the  apprehending  individual  immediately notifies the officer to whom he or she is responsible or an officer of the security police, military police, or shore patrol. An apprehension is effected by clearly notifying the offender that he/she is thereby taken into custody. The order may be oral or written. 2-16 Student Notes:
