also a thing about warfare. only really from franco-prussian war on combat-related casualties started outnumbering non-combat related casualties. (think napoleon's army dying of hunger and exposure during march on moscow). casevac got so good that during intervention in afghanistan american doctors started doing hemicorpectomies, that is amputation above pelvis. also, phaseout and ban of chemical and biological weapons didn't happen because we've got morally better, it's because this shit doesn't work in modern wars
