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 explains the difference between marksman, sharpshooter, and expert; reviews WWII coast artillery and examines one of WWII's most sophisticated missiles, the BAT; and finally checks out the Coast Guard's latest approach to the War on Terror, the Maritime Safety and Security Teams.moreless
