In days of old, if your army had to take on a huge stone castles there was only one option: bunker busting siege weapons like the giant crossbow known as the Ballista and the fearsome Trebuchet! These weapons hurled rocks and flaming kegs to cause mayhem and smash through walls. Today the siege tradition continues, with our military using high-explosives to blow the bad guys out of their foxholes. First, Gunny let's loose massive boulders from an ancient trebuchet catapult against an enemy castle. Then he gets his hands on some old-style gunpowder and recreates the big bangs that were used to bring down enemy bunkers, all the time instructed by committed experts who revel in the history of these amazing weapons. Gunny also visits today's bunker busters--military engineers who bust under, over, and into enemy strongholds.

When today's warriors go toe-to-toe in combat the weapon they rely on is the machine gun. From the crude machines of the 19th century to the slick weapons of today, Gunny takes us on a journey that looks at the engineering development of this rapid-fire battle winner. Learn how the "potato digger" machine gun got it's name, and why a hand held gun developed in 1965 is still the weapon of choice for the toughest warriors on the planet. Ermey compares the machine guns that stormed the beaches of D-Day--the Bren gun and the B.A.R.--with a classic shooting match. Then, Gunny cuts loose with the Special Forces wonder weapon, the MP-5, as used by the British SAS and American Navy Seals

R. Lee Ermey gets hands-on with America's most proven and famous firearms--like the M1 Garand, 1853 Enfield and the 1903 Springfield. Gunny also tests which rifles were the greatest through history, comparing weapons like the American M16 and Soviet AK-47, as Gunny crosses America to show you the engineering evolution that lead to today's rifle.

Go on a journey through history with R. Lee Ermey to see the technology behind the very first round of ammunition. Then hit every important engineering development until Gunny fires the latest and greatest bullet ever designed.

Gunny explores the history of the weapons that ruled the world for thousands of years before guns came.

Gunny gets a first-hand look at the "rocket's red glare" as he demonstrates rockets dating back to ancient China thru today's state of the art self guiding missiles.

Gunny explores the history of shotguns – from a 17th century Blunderbuss to the modern day, gas-assisted M4 Super 90.

R. Lee Ermey takes us through the evolution of the pistol from the flintlock dueling pistols to the rapid fire automatic pistols used today.

In this episode, R. Lee Ermey takes the viewer through the history of the tank from its beginning on the battlefields of World War 1 to it's current use by the military of today.

In this episode of "Lock N' Load with R Lee Ermey" the gunny examines one of the deadliest weapons on the modern battlefield; the machine gun. He shows us the rapid fire destruction the machine gun has unleashed throughout history, starting with the hand-cranked Gatling Gun, to the rapid-fire, electrically powered Minigun. Prepare to lock 'n' load!
