Can you answer these questions on war tanks?

The first tanks were developed for World War I. The very first tank was built in 1915, a year after The Great War started.

World War I was known for its trench warfare, in which heavily armed men hunkered down for fear of being slaughtered by newfangled, high-powered weapons. Tanks were meant to break these long-standing sieges.

The Landships Committee was tasked with developing some sort of armored weapon that would smash the stalemate of the Western Front. The word "tank" was introduced as a code name for these new armored "land ships."

In 1915, the British built a prototype tank named Little Willie. It was designed to be able to cross a wide trench without getting stuck.

Little Willie was a test machine. It never served in combat but it did help the Allies as they worked towards more feasible tank designs.

Little Wille (and subsequent Big Willie) led to the British Mark I tank. This tank was slow and prone to breakdowns but it was certainly safer than traipsing throughout no man's land with only a jacket and a rifle.

The British called it the Little Willie. It was the equivalent of a schoolyard taunt. %0DThey were mocking German Crown Prince Wilhelm.

During the catastrophic horrors of the Battle of the Somme, a few Mark I tanks made their way into firefights. Commanders immediately knew these new weapons had great potential.

In World War I, trenches were topped with endless miles of barbed wire that made life impossible for advancing infantry. France's earliest armored vehicles were meant to get that nasty barbed wire out of the way.

The Germans were dismayed to see British tanks rolling across no man's land. In response, they developed K bullets -- armor-piercing bullets. The K bullets had steel cores and could be fired by typical Mauser rifles.

"Male" tanks had long, protruding cannons. Female tanks were armed with just machine guns. Whether the vehicles were male or female, German infantry wanted nothing to do with British tanks.

The British planned a super-heavy tank called "Flying Elephant," which was supposed to be nearly 28 feet long. It was so big and so heavy that it was never actually completed. Its top speed would have only been around 2 mph.

At the Battle of Cambrai, the British deployed around 400 tanks. The Mark IV tanks found immediate success and pushed back German lines.

By the time this 1917 battle rolled around, the Germans were getting better at fighting armored vehicles. Of the 400 Mark IV tanks sent forward, only about half were ready for action the next day.

The Renault FT was the world's first tank with a revolving turret. Many historians call it the first modern tank in human history.

The Renault FT was the first tank to place the engine in the rear compartment. It had a small crew compartment -- it needed just two men for battlefield operation.

The Mark IV tanks often carried fascine, bundles of sticks and logs strapped to the top of the vehicle. Why? The bundles were dropped on muddy or rough terrain to help the tank pass without becoming stuck.

The Tsar Tank looked like a ridiculously huge tricycle. It had two giant wheels nearly 30 feet in diameter, but the tiny third wheel was a fatal flaw, and it caused the tank to get stuck on difficult terrain.

In the spring of 1918, the Second Battle of Villers-Bretonneux saw the first tank-on-tank battle action. The ordeal was intense … but indecisive.

The A7V was no simple device. The tank needed a crew of at least 18 men. It was a 33-ton monster that featured a 200-horsepower engine.

During World War II, the U.S. deployed mostly the M4 Sherman, a medium tank that was both relatively cheap and very dependable. It was fairly easy to manufacture, which was a huge benefit during an era of expanding industrial warfare.

During World War II, the Soviets created the T-34. It was reliable, powerful and deadly. It decimated the first German units it encountered on the Eastern Front.

The Nazis knew their armored vehicles were outgunned by the T-34, so they built the Panzerkampfwagen VI. It was better known as Tiger, and Tiger tanks terrified Allied forces everywhere.

The Nazis struggled to stop Soviet T-34 tanks, which had thick, durable armor. In desperation, the Germans leveled huge anti-aircraft guns at the tanks and began blasting them.

An MBT is a main battle tank. MBT tanks are extremely maneuverable, loaded with strong armor and feature an array of deadly weapons. MBTs are an improvement on the super-heavy tanks of the World War II era.

Germany began cranking out the Leopard 2 tank -- a main battle tank -- in the 1970s. It has heavy armor, advanced targeting and has been exported to many countries around the world.

The U.S. T95 was the first tank to use composite armor. The armor featured layers of glass and steel that effectively repelled many types of enemy munitions.

The M1 Abrams is the main battle tank of the United States. It's been in service since 1980 and has featured numerous upgrades over the years.

Explosive reactive armor is a bit counterintuitive -- it features a layer of explosives within the armor. If the armor is penetrated, it explodes, with the purpose of destroying the penetrating object before it can do more damage.

The M1 Abrams is a powerful weapon, but at nearly 55 tons, it's one of the heaviest tanks ever. The M1A2, approved in 1990, features a 1,500 horsepower gas turbine engine to get that huge hunk of metal moving.
