Lock N' Load with R. Lee Ermey (2009)

On each episode of "Lock n' Load", R. Lee Ermey takes us on a fascinating ride through the pathology of a featured weapon: where it came from, who thought of it, who improved it, its victories, its defeats, its impact on history and where it is now. R. Lee doesn't start at the beginning. He launches each "Connections-type" journey with that weapon's most modern iteration: for example, unleashing a maelstrom from a Metal Storm gun at one million rounds per minute, then weaving the machine gun's history across the hour, skipping through decades, centuries and milestones as required.
