The other comments already answer this question. But I'd like to add just how massive the DoD is. It's not like how one might imagine a typical military, where the government is basically funding an entity to pay soldiers' salaries, pay for their equipment, and basic necessities and not much else. The DoD on a macro level doesn't really skimp on anything, from research on how climate change will affect its mission to dealing with overwhelming quantities of rust. Plus historically, there are plenty of wars where disease was more deadly than enemy combatants.
