canceled  and  will  be  subject  to  normal  follow-up casualty reporting procedures. CASUALTY  CATEGORIES A casualty category (2, 3, or 4) is associated with each  reported  equipment  casualty  to  reflect  the  urgency or  priority  of  the  casualty.  The  casualty  category, although not a readiness rating, is directly related to the unit’s  Equipment  Status  Resource-Specific  Categories [explained in chapters 5 and 6 of NWP 10-1-11, Status of Resources and Training System (SORTS)] in primary and secondary missions that are affected by the casualty. NAVEDTRACOM   activities   use   four   casualty categories (1, 2, 3, or 4). In this chapter we discuss only non-NAVEDTRACOM    activities. The casualty category (2, 3, or 4) is based upon the specific  casualty  situation  being  reported  and  may  not of  CASREP.  Follow-up  CASREP  messages  (UPDATE, CORRECT, or CANCEL) will reference the INITIAL CASREP  message  DTG. Because of the importance and priority of CASREP message  transmission,  your  CASREP  messages  must  be transmitted even under MINIMIZE conditions. Use standard  naval  telecommunications  systems  (NTS) service  procedures  in  correcting  any  messages  having transmission  errors. CASREP  REPORTING  CRITERIA Each type of CASREP has own its reporting criteria, which  we  have  described  below. INITIAL  CASREP necessarily agree with the unit’s overall readiness status. The  casualty  category  is  reported  in  the  CASUALTY  set Any  time  you  prepare  an  INITIAL  CASREP, (section   of   the   CASREP)   and   is   required   in   all remember  the  following  criteria: CASREPs. 1. Submit only one initial casualty in the INITIAL Figure 5-2 shows a decision logic tree that provides CASREP; if some of the required data is not available a logical approach in determining the casualty category at reporting time, use your best estimate in the INITIAL and  whether  or  not  a  CASREP  is  required.  Figure  5-3 CASREP and correct your estimate as soon as possible shows the criteria for determining the casualty category. in an UPDATE CASREP. MESSAGE FORMAT 2. In an Initial CASREP, identify, to the appropriate level  of  detail,  the  status  of  the  equipment,  parts,  and A CASREP message consists of one or more sets that  contain  the  information  required  to  report  the particular  casualty.  These  data  sets  are  preceded  by  a standard   Navy   message   header   consisting   of precedence,   addresses,   and   classification.   Specific guidelines for both the message header and data sets to be used are contained in chapter 4 of NWP 10-1-10, Operational Reports. Detailed information for typing each  type  of  casualty  report  (INITIAL,  UPDATE, CORRECT,  and  CANCEL),  with  examples  of  CASREP situations for each type, is also provided. The CASREP message is always serialized with the MSGID  (message  identification)  set,  that  appears immediately  after  the  message  classification  line.  The serial numbers are sequential from 1 through 999 for each  CASREP  originated  by  a  unit.  These  serial numbers  are  not  repeated  until  a  new  sequence  of numbers 1 through 999 has begun. A new sequence of numbers  starts  after  the  unit  has  submitted  CASREP message number 999. The  date-time  group  (DTG)  of  the  CASREP message  transmission  is  the  effective  time  (“as  of  time”) assistance  requirements.  This  is  essential  to  allow operational and staff authorities to apply the proper priority to necessary resources. 3. You may also submit an Initial CASREP if you only need outside assistance; i.e., no parts are required to  correct  the  equipment  casualty. 4.   When   a   casualty   results   from   inadequate general-purpose  electronic  test  equipment  (GPETE)  or preventive maintenance (PMS), list the affected system as the subject of the INITIAL CASREP, and report GPETE   or   PMS   as   the   cause   in   an   AMPN (Amplification)  data  set. 5. Use an ASSIST data set to report whether or not you need outside assistance to repair an equipment casualty. 6. When you need assistance or parts to repair a casualty, report schedule information in the RMKS set for a full 30-day period, beginning on the earliest date that you can receive the assistance or parts. You may also report any effect the casualty is expected to have on your unit’s employment during the 30-day period. 5-7
