This article describes the experience of nutrition support practitioners, specifically dietitians, providing care to combat casualties. It provides a brief overview of dietitians' induction into armed service but focuses primarily on their role in providing nutrition support during the most recent conflicts in Iraq and Afghanistan. The current system of combat casualty care is discussed with specific emphasis on providing early and adequate nutrition support to U.S. combat casualties from injury, care in theater combat support hospitals (CSHs)/expeditionary medical support (EMEDs), and en route care during critical care air transport (CCAT) up to arrival at treatment facilities in the United States. The article also examines practices and challenges faced in the CSHs/EMEDs providing nutrition support to non-U.S. or coalition patients. Over the past decade in armed conflicts, dietitians, physicians, nurses, and other medical professionals have risen to challenges, have implemented systems, and continue working to optimize treatment across the spectrum of combat casualty care.
