  3-106. The battalion S-1 has responsibility for preparing casualty reports and maintaining the status of
  assigned and attached personnel at MTFs with assistance from the HR squads. Battalion S-1s forward all
  original casualty forms to the brigade. The battalion ensures all Soldiers and DOD and DA Civilians carry
  and are trained on the use of the DA Form 1156 (Casualty Feeder Card) to ensure effective reporting when
  casualties occur. The battalion processes casualty reports using DA Form 1156 as a template to capture the
  information needed to complete a casualty report and ensures the form is filled out and submitted to the
  brigade S-1 or into DCIPS without delay, or as soon as the tactical situation permits. Currently, field grade
  officers must approve casualty reports for accuracy and completeness before submission, but losses at the
  scale of LSCO against a peer threat may require an exception to this policy to ensure timely reporting.
  Battalion S-1s should also coordinate any information they receive on mortuary affairs or personal effects
  disposition with the battalion S-4. Refer to ATP 1-0.1, Appendix D, S-1 Assessment, and use the list to assess
