--- "How many were killed in action and there’s no record of it ?"

Gee, I don't know. Given the reflections from my era in the US Army, we still have some few MIAs from Vietnam. Your question will likely never be answered for anyone on any side.

In your opinion, do you think the US did leave some living MIAs behind as prisoners because getting them back was too difficult and would have required continuing the war there?
