Sorry I am failing to see your point.
Are you implying that the fact there are no common soldiers famous for liberating concentration camps, means that saving further millions that would be killed by the eventual Nazi occupation of Europe, is in vain?
You - who ask for people to sacrifice their lives in the most horrific ways - don't even care to know the names of any of those who have done that before.
To most people, these soldiers are just part of a nameless and faceless mass of flesh and meat to be utilized and expended.
Who would want that to be his destiny? Certainly not you, because you are here on HN typing and not putting your life on the line to defend innocent people in Ukraine, in Haiti, in Africa, and so on.
