Yes I know panzergrenadiers were a real type of infantry. But the camo smock...well, I've never seen it myself.
I'm a 2nd SS Panzergrenadier Division "Das Reich" reenactor. All the camo smocks I've ever seen can probably be found at these websites:

On the other topic: Yeah the whole Reich was one big complex system. Obviously anybody in Germany could have believed in Nazi politics. And in the early days of the reich alot ot people did. But it's not fair to label the entire German population as Nazis. After all, there were 17 different assassination attempts to kill Hitler within the Wehrmacht itself
