Q: The film opens in Korea as Sgt. Zack (Gene Evans) crawls up out of a killing pit after an enemy bullet has passed through his helmet without killing him. He is aided by a young Korean boy he nicknames "Short Round" (William Chun) as he tries to get back to American troops. Zack meets a Thompson (James Edwards) a Medic who has escaped from the Koreans like Zack and the trio travel until they meet a platoon lead by Lt. Driscoll (Steve Brodie) who commands with a rigid inflexibility. The group moves to what they think is an abandoned Buddhist temple to set up a command post. During their process of establishing occupation of the countryside they realize many things about their differences and likenesses as men and as soldiers and find that they continue to be challenged by the Korean Army and themselves.
A:
Who is the commander with rigid inflexibility?
