China finally admits to fate of US POW from the Korean War.

After the war, the lack of full accountings of a large number of soldiers, as well as dodgy POW management in North Korea, left many Americans convinced that there may still have been secret POW camps hidden in Manchuria.

Which was integrated into STARSHIP TROOPERS in the form of the "leave no man behind" doctrine, and was in fact alluded to very directly in one of Johnnie's OCS lectures.

Obviously, I'll have to finish watching the series to see if it's covered in the Japanese adaptation.
