Military medicine has long driven innovations that shape civilian trauma care. Multiple life-saving U.S. military medical practices and technologies, such as vaccines, whole blood transfusion, and Tactical Combat Casualty Care, have transitioned into civilian use. However, lacking a centralized and comprehensive repository documenting these translational technologies makes it difficult to fully understand and analyze the scope and effectiveness of military-to-civilian medical technology transfers. This scoping review aimed to identify and map U.S. military medical innovations that were translated into civilian trauma care since World War II. The review was performed using PubMed, CINAHL, Embase, and Google Scholar for English-language articles published from 1945 to present relating to military-to-civilian translation of medical innovations, battlefield trauma care, and military-civilian partnerships. Ninety-two total articles were identified and reviewed based on inclusion and exclusion criteria, resulting in the analysis of 13 studies that highlighted innovations such as tourniquets, REBOA, and damage control resuscitation. Four key themes emerged: translation, clinical effectiveness, feasibility, and policy adoption. Military innovations are increasingly adopted in civilian care, but systematic frameworks and centralized documentation remain lacking. Despite the successes in these fields, translation remains inconsistent due to a lack of standardized terminology and formal pathways. Standardization, collaboration, and outcomes research are essential to bridge gaps and institutionalize best practices. Strengthening cross-sector collaboration and investing in implementation research are essential to fully realize the civilian benefits of battlefield innovations.
