As Michael Brooks would say, hate the policy not the person. Yes a good many of them were probably complicit in war crimes or committed them themselves but if you're in healthcare then you've already made a choice to help people regardless of their politics or life choices. Would you not help someone who's a trump supporter or Q Anon nut? Would you not help a cop? Of the groups mentioned, most rank and file soldiers are working class and used the military as one of few options to get a job with benefits so I don't blame them for how our military industrial complex is wielded on the world.
I'm not judging your hatred because I agree on principle, but if that's how you feel then you should try to transfer away from military locations or attempt a career change.
