I saw this movie on TV many years ago. Unfortunately, you won't find anything written about it that does it justice. The cultural conflicts depicted in the film go beyond that between the African veterans and their French army masters. Early in the film, there's a conflict between the African veterans and an American military contingent. Instead of stepping in and resolving it, the French allow it to fester and sneeringly look down on the Americans as just a bunch of hopeless racists (how very very European of them). When the French are finally dragged in to resolve things, there's an amusing scene where the de facto leader of the Africans (being the only man in the camp fluent in French and English) has to act as interpreter for his supposed superiors.
I was dfrawn into the movie initially because it features a mute, shell shocked, excitable character amongst the African veterans who wears a German army helmet and whose frequent bouts of anxiety are quelled only by the sound of the German propaganda song Lili Marleen. It's interesting characterization amongst many in this very underrated movie.
