Which item is not required to be provided to HQMC upon reporting a casualty?

The item that is not required to be provided to Headquarters Marine Corps (HQMC) upon reporting a casualty is the TBIR, or the Tactical Battle Injury Report. While TBIRs can serve as important documentation in certain contexts, they are not a mandatory requirement when reporting a casualty to HQMC. Instead, the focus is on ensuring that critical information pertinent to the casualty is accurately communicated and documented, which typically includes additional documentation, medical records, and death certificates.

These latter items provide essential evidence and documentation needed for tracking casualties, processing benefits, and supporting the families of the deceased or injured. The absence of a TBIR requirement underscores that while it may have utility in specific operational contexts, it does not hold the same level of necessity as the other documents outlined for formal reporting procedures.
