First, a few points of clarification: This question mentions the portrayal of German soldiers’ treatment of Jews in films, and asks about how accurate it is. I am assuming this refers to fictional portrays in feature films. There are, however, existing newsreels shot by the Germans themselves, which capture examples of Germans humiliating Jews. So it should go without saying that those examples of Germans mistreating Jews are accurate. Second, the question mentions “Nazi soldiers”. I just want to point out, as a point of clarification, that there was no “Nazi army” – just a “German Army”. The use of the term ‘Nazi’ can be seen as a way to frame the question temporally, but one of the side-effects of using this terminology is to separate the behaviour of German soldiers in WWII from German military actions before and after that war. This was not an entirely new military structure parachuted in by Hitler, which lasted from 1933 until 1945 and then vanished. It was an army with a great deal of continuity to the German military of WWI and the 1920s. And it was not fully purged after WWII ended. I realize this is not at the core of the question, but I’m a big believer in fighting for accurate terminology, because I think that helps to build the most accurate and clear picture possible. Connected to this, I am not sure if “Nazi soldiers” in the question means all German soldiers, German soldiers who were also Nazis (members of the Nazi Party), or specialized troops like the SS (arguably the most deserving of the label “Nazi soldiers”). I am going to focus on the least Nazified of the three examples, general German soldiers. One can imagine that the treatment of Jews by the SS was even worse than that of average German soldiers whose political beliefs and ideological affiliations were much more varied. The fact that soldiers in the German army participated in the humiliation, harassment and dehumanization of Jews is well-documented. In the famous Garman exhibition from 1995 that challenged the myth of the "clean Wehrmacht", photographs taken by German soldiers were put on display, which showed soldiers not only humiliating Jews, but recording themselves doing it for posterity. German photos that have survived show Jews being forced to wash German vehicles, give the Nazi salute, as well as soldiers posing next to Jews to highlight the differences between themselves (as so-called Aryan specimens) and Jews in classic religious dress. In her book Photographing the Holocaust, Janina Strut writes about how German police, SS men and soldiers frequently humiliated Jews in public places, cutting the sidelocks of men while posing, smiling beside them as if in a holiday photo (p.63-64) In his article "Wehrmacht Propaganda Troops and the Jews", Daniel Uziel lays out the many ways the propaganda troops that were attached to the German Army (Wehrmacht), known as Propaganda-Kompanien or or PKs, created and recorded scenes of Jewish humiliation. They entered ghettos to photograph Jews there; they recorded film clips, etc. (Some clips of which were later used in Nazi propaganda films like Die Ewige Jude). So, not only were soldiers humiliating and degrading Jews, but it was an official role of the military propaganda troops to capture this happening. In the article, Uziel adds that: "It is well known that many soldiers had antisemitic prejudices before joining the military and that the German military was itself tainted by antisemitism even before the Nazis rose to power. This matter is strikingly evident in soldiers’ letters and in numerous photographs that show German soldiers humiliating Jews." (p.29) This degradation served a purpose-- dehumanizing Jews through intense, public humiliation allowed Germans to separate themselves from these people, to see them as lesser by treating them as lesser, thereby creating a justification for future terrible treatment and even murder. (A self-fulfilling prophecy – people aren’t treated like this, so if we treat you like this, you must not be people.) Not all German soldiers treated Jews in this manner. It is impossible to offer any estimates about how common such behaviour was or was not. But, as the above examples show, the behaviour was not merely tolerated, it was officially sanctioned and even encouraged in many cases. So I think it is fair to classify this as the standard treatment Jews recieved, certainly in the occupied east (Yugoslavia, Poland, the USSR), though not necessarily representative of the behaviour of every German soldier.
