What happens when an American dies in Ukraine but can't be recovered?

I am sorry for the loss of an American. But they should know that getting injured or killed is a strong possibility when engaging the Russian Army. The Russians are leaving their own people to rot in Ukraine, so they surely won't help recover an American enemy.

What happens if a Korean or Vietnam or Afganistan vet dies. Its the same thing. If these Americans go to fight for a foreign country, they should know what they are getting into. A lot of veterans are killed on the battlefiels and some of those bodies aren't ever recovered. War is hell and it sucks but casualties are a fact. I hope that his remains are recovered to the U.S.
