Syria.
You see, the reason we have laws and customs of war is simple:
Don't do this and we won't do it to you.
It is pragmatic to shoot medics. But they'll start shooting your medics, and then it becomes just shooting up as many of the guys on the wrong side, regardless of how armed or innocent they are.
The point of the laws and customs of war is to try and ensure war doesn't become atrocity met with atrocity.
