I think they mean communicable diseases, not combat injuries. For example, around 2/3rds of the military deaths in the American civil war were from disease, not combat. I don’t think much of the medical advances that prevent that came from combat medicine.

Triage and ambulances come from battle medicine [1]. (Not sure about communicable-disease prevention.)

Right, those are relatively minor improvements compared to soldiers no longer dying en masse from typhoid, smallpox, measles, etc. Good improvements to be sure, but not quite as significant.
