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 learns about one of the biggest threats facing today's soldiers, Improvised Explosive Devices, and then offers up a history lesson on the battle for Guadalcanal. Gunny then profiles the Sullivan Brothers, and then the legendary Rough Riders of the Spanish-American War, as well as the modern-day Rough Riders.moreless
