  3-116. All persons with knowledge of a casualty will report to their chain of command using the DA Form
  1156. The commander of the unit in which a casualty occurs has the responsibility for initiating the casualty
  report. The DA Form 1156 is used to submit an initial report when a casualty incident is observed. It is used
  to document critical information, which is forwarded to the battalion S-1 section for submission to the brigade
  S-1 section. Casualty information is frequently incomplete on the battlefield. This should not delay the initial
  report submission. Updated casualty information is provided as it becomes available. The brigade S-1 section
  submits the initial casualty report using DCIPS to ensure all echelons have visibility. Based on guidance from
  the combatant commander, the ASCC G-1/AG may delegate authority for corps-level commanders to release
  casualty reports directly to CMAOD with a copy provided to the theater CIC. Casualty reports must be
  verified against available information systems.
  3-117. Human resources squads performing casualty reporting missions work with the ASCC HROC
  operating the theater CIC. The G-1/AG and S-1 at echelon have overall responsibility for casualty reporting
  on behalf of their formations; SRC 12 HR squads supplement their efforts with information from Role 3 MTF
  and mortuary affairs company HQ and additional capacity at General Officer HQ and potentially within
  brigades. Soldiers may immediately medically evacuate to an MTF where the HR squad (casualty liaison
  element) interact face-to-face and generate a DCIPS report for submission, in coordination with the Soldiers’
  unit, to the theater CIC.
  3-118. For injured and ill Soldiers, CMAOD contacts the supporting installation casualty assistance center
  who in turn contacts the Soldier’s rear detachment. The rear detachment makes telephonic notification for
  injured and ill Soldiers and then reports back to the installation casualty assistance center when notification
  is complete. Once notification is complete, CMAOD contacts the NOK and prepares Invitational Travel
  Orders to travel to the Soldier’s bedside if the Soldier’s doctor requests their presence. The CMAOD contacts
  the supporting CONUS and/or overseas CONUS installation casualty assistance center to coordinate for
  notification of NOK (as per the DD Form 93) for deceased Soldiers. Figure 3-5 depicts an illustration of the
  casualty reporting and tracking flow.
