Which registry identifies combat casualties?

• A. AFIP DNA registry
• B. Nun Study
• C. National Marrow Donor Program
• D. Trauma Registry

Answer: (A)

Identifying combat casualties relies on linking remains to a known individual through genetic evidence. A DNA registry designed for military identification stores DNA profiles from service members and reference samples, making it possible to match remains found in combat to the correct person. This targeted purpose is what makes it the best fit for identifying combat casualties.

Other registries serve different aims: a trauma registry collects data on injuries and outcomes for research and quality improvement; the National Marrow Donor Program focuses on matching donors for bone marrow transplants; and the Nun Study is a long-term research project on aging and Alzheimer's disease. None of these are established for identifying unknown military personnel through DNA, so they don’t fit the purpose as well.
