Sure, the US could send our Negros to kill their Negros, I wonder how that would work out.
Wait, no I don't.
I don't see this working out well for the US presence either.
Actually the bulk of combat deaths still fall primarily on European males under 40. They die at a rate far exceeding their proportion of the overall population and of their demographic. Even stripping women out of the calculation they are much more likely to die while deployed.
