statements  of  witnesses  under  oath,  it  should use  the  oaths  prescribed  in  JAGMAN  0212b. The  Privacy  Act  requires  that  a  Privacy Act   statement   be   given   to   anyone   who   is requested   to   supply   personal   information   in the  course  of  a  JAGMAN  investigation  when that  information  will  be  included  in  a  system of  records.  Note  that  witnesses  will  rarely provide  personal  information  that  will  be retrievable   by   a   witness’   name   or   other personal  identifier. Since  such  retrievability is  the  cornerstone  of  the  definition  of  system of  records,  in  most  cases  the  Privacy  Act  will not   require   warning   anyone   unless   the investigation   may   eventually   be   filed   under that  individual’s  name. Social  security  numbers  should  not  be included   in   JAGMAN   investigation   reports unless  they  are  necessary  to  precisely  identify the  individuals  involved,  such  as  in  death  or serious  injury  cases.  If  a  service  member  or civilian   employee   is   asked   to   voluntarily provide   their   social   security   number   for   the investigation, a Privacy Act statement  must be provided. If  the  number  is  obtained  from other  sources,  the  individual  does  not  need  to be  provided  with  a  Privacy  Act  statement. The  fact  that  social  security  numbers  were obtained  from  other  sources  should  be  noted in the  preliminary statement of the investigation. If   prosecution   for   a   suspected   offense under  the  UCMJ  appears  likely,  the  witness suspected  of  the  offense  should  be  warned under   Article   31(b),   UCMJ,   and   JAGMAN 0170.   Appendix   A-1-m   of   the   JAGMAN shows  the  proper  form  to  be  used.  The  IO should   collect   all   relevant   information   from all   sources-other   than   from   those   persons suspected of   offenses, misconduct,    or improper performance of   duty–before interviewing  the  suspect. A  member  of  the  armed  forces,  before being  asked  to  provide  any  statement  relating to  the  origin,  incurrence,  or  aggravation  of any  disease  or  injury  suffered,  should  be advised of the statutory right not to make such a  statement.  Appendix  A-2-f  of  the  JAGMAN contains  a  proper  warning  format  and  without this  warning  the  statements  are  invalid. The  appointing  order  directs  completion  of the  IO’s  report  within  30  days  of  the  date  of the  appointing  order. JAGMAN   0202c established   the   following   time   limits   for processing   JAGMAN   investigations: l   The   CA   prescribes   the   time   limit   the f a c t - f i n d i n g    b o d y    h a s    t o    s u b m i t    i ts investigation. This   period   should   not normally  exceed  30  days  from  the  date  of  the appointing  order;  however,  this  period  may  be extended   for   good   cause. Always   include requests  and  authorizations  for  extension  as enclosures  to  the  investigation. l   The   CA   and   each   subsequent   reviewer have   30   days   (20   days   in   death   cases)   to review   the   investigation. Reasons   for exceeding these time limits must be documented  by  the  responsible  endorser,  and deviations  must  be  requested  and  approved  in advance  by  the  immediate  senior  in  command who  will  next  review  the  investigation. INVESTIGATIVE   REPORT The investigative report, submitted in letter form,  consists  of  the  following  items: l   A   preliminary   statement l   Findings   of   fact l   Opinions l    Recommendations l   Enclosures 9-21
