My brother a retired combat vet designed an amazing tattoo to represent all fallen and had it tattooed on his forearm when he retired. It was like hands comming out of the sky holding crosses and dog tags etc.
Now to represent the fallen of Iraq and Afganistan You could perhaps have the gravestone and then do like a bargello effect pouring out of the stone or something like that I can see it in my mind .If you are wanting actual names I have no Idea but I am sure someone here will.
I commend you for taking this on I will think on it and see what else I think up.
