I cannot in good conscience let the Holocaust denial nut have the only review of this. This film in no way supports holocaust denial. In fact, it fully acknowledges the Holocaust, including the fact that of most of the Jewish relatives of the "Mischling", a derogatory term meaning "mutt" in German and applied to the Jewish German soldiers featured in the film, were murdered by the Nazis.
The film explores the myriad reasons why Jewish soldiers wound up in the German army. Many were drafted when the Nuremberg racial laws contained loopholes for Germans who were 1/4 or 1/8 Jewish. These loopholes were later plugged and kept more Jews from joining. Some lied about their ancestry and joined because it was safer to be a German soldier in combat on the front lines than to be a Jewish civilian in any area under German occupation. Most of these soldiers were just that-soldiers; few were Nazis.
The claim about 40% of the German Army's officers being Jewish is ludicrous. This film pegs the total number of 1/4 and 1/8 Jews at no more than 150,000, and considering the millions of men in German uniform that is a small number indeed. The film also points out that few of the "Mischling" were of high rank. Indeed, many turned down promotions for fear that their ancestry would be discovered. It was easier to be an anonymous Jewish private than officer.
The film is sobering in telling what happened to these soldiers' families. How were these soldiers rewarded for their service? By having their families murdered by the Nazis, the same fate intended for these soldiers once their services were no longer needed.
It is an interesting documentary, though, if you accept the historical fact of the Holocaust. If you are looking for something to confirm your Holocaust denial conspiracy theory, as the previous reviewer apparently is, you should look elsewhere.
