This must be one of the worst "war" movies ever made. There are only about a dozen cast members. Most of the war scenes are stock footage. They did spring for the rental of a tank, though. There isn't much of a story, and what there is of it makes little sense. The depiction of the Koreans, both the good guys and the bad guys, is insulting. The special effects don't come close to recreating what it's like inside a tank. However, it's only 80 minutes long, and there are a couple of famous names in the cast (Frank Gorshin and Edward G. Robinson, Jr.). It's a hoot to watch.
