Local   commands   may   subdivide   SSICs   by adding arbitrary numbers or words after the SSIC. For  example: Primary  Numerical  Subject  Group Arbitrary  Numbers 5600   Micrographics   Publications,   Print- ing, Duplicating, and Reproduction 5600/1   Protestant Worship Bulletins 5600/2   Roman   Catholic   Worship Bulletins 5600/3   Bulletins   for   Special Occasions Arbitrary   Words 5600/Bulletins   for   Special   Occa- sions 5600/Protestant Worship Bulletins 5600/Roman   Catholic   Worship Bulletins Secondary   Numerical   Subject   Group Arbitrary  Numbers 5760   Organizations,   Associations, Societies,   Individuals,   and   Com- mercial Enterprises 5760/1 5760/2 5760/3 5760/4 Military Chaplains’ Asso- ciation American  Bible  Society American  Red  Cross Navy  Relief Arbitrary   Words 5760/American   Bible  Society 5760/American   Red   Cross 5760/Military  Chaplains’  Associa- tion 5760/Navy   Relief Tertiary  Numerical  Subject  Group Arbitrary  Numbers 1601  Duties  and  Watches 1601/1 1601/2 1601/3 Duty   Chaplain   Watch List Liturgist Schedules Duty  RP  Watch  List Arbitrary   Words 1601/Duty  Chaplain  Watch  List 1601/Duty  RP  Watch  List 1601/Liturgist  Schedules NOTE:  When  arbitrary  words  are  used  to  sub- divide   SSICs,   files   are   normally   arranged   in alphabetical   sequence   within   each   numerical group. The Chaplains Manual (OPNAVINST 1730.1) lists  examples  of  arbitrary  subject  breakdowns which  are  unique  for  subjects  relating  to  the Chaplain Corps and the Command Religious Pro- gram.  Command  chaplains  and  RPs  should  con- sult  this  instruction,  in  addition  to  SECNAVINST 5210.11 and SECNAVINST 5211.3, for guidance whenever  an  arbitrary  subject  is  used. CRP  FILING  SYSTEM BY SSIC Specific guidance is provided in OPNAVINST 1730.1  concerning  a  standardized  SSIC  filing system  for  subjects  pertaining  to  the  Chaplain Corps and the CRP. The RP should consult this instruction  whenever  questions  arise  concerning these   subjects.    It  should  be  noted  that  the modified  filing  system  outlined  in  OPNAVINST 1730.1 is not a substitute for the Department of the Navy standardized filing system which is con- tained   in   SECNAVINST   5210.11   and   SEC- NAVINST   5211.3.   The   modified   filing   system outlined  in  OPNAVINST  1730.1  is  designed  to meet the unique needs of the Chaplain Corps and the  CRP  in  addition  to  meeting  the  basic  re- quirements  contained  in  SECNAVINST  5210.11 and   SECNAVINST   5211.3. 3-9
