The Glory Brigade is a standard Korean War combat drama with a few interesting plot wrinkles. Victor Mature stars as Lt. Sam Prior, an American of Greek extraction. While trying to cross a bridge into Red territory, Prior loses most of his men, a fact he attributes to the seeming cowardice of the Greek UN troops. Eventually he realizes that his assumptions about the Greeks were mistaken, and further proof of their courage is offered during a later confrontation with the North Koreans. Alexander Scourby co-stars as Lt. Nikias, CO of the Greek detachment, while Lee Marvin enjoys one of his best early roles as Prior's corporal.
