R. Lee Ermey, who played the sergeant in Full Metal Jacket, applies his gruff sense of humor in this half-hour series that answers viewers' mail about what the armed forces were, and really are, like! In this episode, he discovers why the military uses silencers in a live-fire demonstration; then checks out the weapons and gear of Japanese soldiers in WWII's Pacific Theater; and finally catches up with the tough new Coast Guard HITRON teams.
