Yes, folks, before he lost his soul in Disney garbage junk, as James Neilson, James B Clark, or Robert Stevenson, Hal Bartlett was a damn good director, a promising film maker, and this gritty, tough war movie - speaking of the Korean conflict - is the best proof, with a Sidney Poitier in a terrific performance, during a period when civic rights for Black people were at stake. I guess this is an underrated war film, which scheme is in the same line of THE LOST PATROL, but I admit that many war films were too. War movies and not war dramas where you can have some romance behind the front line with a female character. Here, you have only one supporting female, that's all. Unfortunately the ending is a bit lousy, ankward to me. I am sure Bob Aldrich, who could have been in charge for such a film, would have given us something totally different. Despite its quality, this movie can be seen as a didactic message. Such a shame.
