The COMBAT Care Act authorizes the Secretary of Defense to establish joint education and training programs with foreign military forces focused on military trauma care and medical research. The programs would include sharing combat casualty care lessons, conducting joint conferences and professional exchanges among military medical professionals, collaborating on health policy and medical logistics, conducting joint research on emerging weapons' health effects, and building capacity for trauma care systems. The bill also allows the Secretary to provide training to foreign militaries on topics including military trauma care, combat wound infection, post-traumatic stress disorder prevention, and non-combat medical care. The Secretary of Defense would work with the Secretary of State to establish these partnerships and would use existing statutory authorities to implement the programs. The legislation does not specify dedicated funding amounts or implementation timelines.
