Triggers: Weapons That Changed the World - Season 2 (2013)

For today's elite warriors, their last line of defence are the Spec Ops Pistols. Host Wil Willis tests the Navy Seal Sig Sauer P226, then fires the greatest forerunners like Jame Bond's Walther PPK, the Soviet Tokarev and the massive Desert Eagle.

The M1 Abrams Tank is the world's most potent armored vehicle. We'll track its development through such forerunners as the WWII-era M18 Hellcat and the Cold War-era Soviet T-55 tank and see why these Â"beast-boxesÂ" have ruled ground warfare for decades.

The light machine gun launched mobile warfare by blending massive firepower with the portability of a rifle. We'll see the evolution of this revolutionary weapon from its use in World War I to its modern incarnation Â- the SAW or Squad Automatic Weapon.
