Knight's Armor/WWI Backpack/Landmine
R. Lee Ermey, who portrayed 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! Shot on location, Ermey reads the questions on air and then sends them out to military experts in the field for answers and brief demonstrations. Ermey learns about the different pieces of a 15th-century knight's armor; what was inside a WWI infantry back; and what makes up a landmine.

Metal
Metal constitutes the very essence of the modern world; the cadence of our progress sounds in the measured ring of the blacksmith's hammer. From soaring skyscrapers and sturdy bridges to jet planes and rockets, metals play a key role. Our journey begins before the Bronze Age and takes us into the shiny future when new metal structures--engineered at a molecular level to be stronger, lighter, and cheaper--shape human progress, as they have since man first thrust copper into a fire and forged a tool.
