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 dresses up as a Civil War Marine Corps sergeant. He performs live-fire demonstrations with the Union's Springfield rifle, the Confederacy's Enfield rifle, the 1842 Springfield muzzle loader, and a cannon. He also cooks up the civil war version of an MRE, salt port and hardtack.moreless
