About This Quiz

By comparison, desert sands and steep mountains look almost bearable. The oceans and lakes of the world stand as one of the biggest challenges for militaries looking to accomplish tough objectives while trying to survive bullets and bombs. To that end, many nations build and maintain amphibious assault vehicles of all kinds, all in the hopes of defending their interests. Can you withstand the rough waves of this amphibious war vehicle quiz?

Vehicles like tanks and Humvees have proven their worth through years of tough combat. And although they can splash through puddles, even small ponds can stop them in their tracks. Amphibious combat vehicles, on the other hand, can tear across both beaches and water while keeping troops safe. Do you know the wartime histories of these famous craft?

They feature big in action movies, too. Any fan of Jackie Chan movies will remember his epic fight scene that took place on a hovercraft careening through city streets. Heroes from GI Joe to the Street Fighter crew have used amphibious vehicles to great effect.

From the beaches of Normandy to the horrors of Guadalcanal, amphibious military vehicles don’t just go in with the tide … they change the tide of war. Splash through this epic war vehicle quiz now!

In what war did amphibious vehicles first make a big splash?

In the First World War, amphibious vehicles weren't a major factor. But in WWII these vehicles weren't just important -- they may have altered the course of human history. For the better, we might add.


What's the purpose of an AAV?

AAVs are amphibious assault vehicles. Their number one job is to whisk troops and gear ashore so that they can begin the mission.

The DUKW was a type of amphibious truck that had a major impact during which conflict?

The DUKW, or duck boat, was an incredible tool for the Allies during WWII. This amphibious truck moved men and materiel onshore in many war zones around the world.

Duck boats were no children's bathtub toys. These WWII stars were 31 feet long and featured six wheels, two in the front and four in the back.


In WWII, LVTs became iconic. What does LVT stand for?

The first LVTs didn't have armor. But it did not take long for the Allies to incorporate armor onto these vehicles, which would make vital beach landings in June 1941.


What sort of reputation did Gama Goats acquire during the Vietnam War?

Gama Goats look rather unwieldy -- like topless Jeeps dragging trailers. But they were extremely capable at tackling hard terrain in Southeast Asia.


What did the "D" in DUKW boats stand for?

In the boring military nomenclature of the day, the "D" stood for "Designed in 1942." Some duck boats that survived the war are still used as tourist rides, sometimes with tragic results.

Yes, you really can make a huge earth mover float. The M520 Goer used its massive tire tread for forward motion.


What sort of armor did DUKW (duck boats) have in WWII?

Duck boats were never meant for the throes of real combat. They were meant to get troops moving in watery areas. They had almost no armor, in large part to maximize buoyancy.


In WWII, the Germans developed the Landwasserschlepper, which was essentially what?

U.S Marines used duck boats to cross coral reefs in the Pacific Theater. How did that play out?

Coral reefs are known for their sharp edges. But equipped with tough tires, the duck boats were able to roll right over them and into ferocious battle with the Japanese.


True or false, after WWII, were LVTs decommissioned from the U.S. military?

DUKW boats were exceptionally capable at attacking and traversing beaches in WWII. The Allies built and used more than 20,000 of these marvels to beat the Axis.
