Former Army Ranger and Air Force Para-rescueman Wil Willis hosts Military Channel's newest look inside the history of modern warfare in Triggers: Weapons that Changed the World. Combining history, science, technology and revealing demonstrations, this cutting-edge series examines the evolution of firearms and how the development of each one changed the face of combat forever. With access to the top firearms collections in the world, Willis takes viewers on an all-inclusive look into each weapon as he thoroughly examines, tests, critiques and fires each one.

In each episode of TRIGGERS, Willis is joined by historical and technical experts to test a series of iconic firearms and examine what made each one unique from competitors in its class. Gun-mounted cameras and high-speed photography capture every moment of the bullet's trajectory, featuring its explosive escape from the barrel to the powerful force the impact makes on its target. Each weapon has an antecedent that sparked its development, as well as a successor that improved upon its technology—or was developed in response to its supremacy. Each was developed for one reason: to gain a competitive edge over the enemy, and the winner was the biggest, best or fastest weapon.

Episodes explore battle rifles from the musket to the modern day sniper rifle, submachine guns, artillery, and even the AK-47, a Cold War creation also known as the single most deadly firearm in history. The series also looks at the Rocket Propelled Grenades (RPGs), known as the AK-47 of rockets. This episode traces hand-fired rockets from their origin centuries ago as ancient Chinese projectiles to the new kid on the block, the Swedish-made AT-4.
