Soldiers are just people like you and me

Cause those are Nazis.

I don't think a child that young of age could recognize a Nazi if he saw one...

its not correct to call them Nazi, the Nazis where a political group in Germany. those were German soliders who dont have a political party. they follow the orders of any party

Well...kinda? The whole Wehrmacht had to swear loyalty to Hitler, but they also had an extremely complicated relationship with the party.
