The DoD funds a lot of medical research to improve combat readiness. When I was an academic researcher, we were working on a project that was partially DoD funded to develop a diagnostic device which was meant for personalizing medication for patients undergoing cardiac procedures, but the military was interested in using it for developing personalized versions of QuikClot for soldiers who experienced battlefield trauma.
I also worked for a company which had several novel therapeutics for agents commonly used in bioweapons in their pipeline and the DoD was funding parts of that as well.
