There was a group called the Nazi Mobile Killing Squads, they were there to exterminate the Jews. Adolf Hitler wanted to kill Jews a better way so that's when the Nazi Mobile Killing Squad was formed. They were ordered to kill any Jew that they saw. The Nazi Mobile Killing Squad were not real soldiers they were just a group of people who hated the Jews. There guns were faulty and they had to conserve as much ammo as they could, the better guns went to the real soldiers for the other war that Germany was in. To save ammo when there were a Jew and a Child that was also a Jew the Nazi Mobile Killing Squads would make both of the child and adult hold each other and then shoot them hopping that it would kill them both or the adult will just land on the child and making it hard for the child to breathe.
