tanks
With machine guns reinforcing massed rifle fire from the defending trenches, attackers were mowed down by the thousands before they could even get to the other side of “no-man’s-land.” a heavily-armored vehicle could advance even in the face arms fire. Add some serious guns and replace the wheels with armored treads to handle rough terrain, and the tank was born. -
Mobile X-Ray Machines
With millions of soldiers suffering grievous, life-threatening injuries, there was obviously a huge need during the Great War for the new wonder weapon of medical diagnostics, the X-ray. By October 1914, Marie Curie, she had installed X-ray machines in several cars and small trucks which toured smaller surgical stations at the front. -
Flamethrower
Their true potential was only realized during trench warfare, however. After a massed assault on enemy lines, it wasn’t uncommon for enemy soldiers to hole up in bunkers and dugouts hollowed into the side of the trenches. Unlike grenades, flamethrowers could “neutralize” enemy soldiers in these confined spaces without inflicting structural damage. The flamethrower was first used by German troops near Verdun in February 1915. -
Poison Gas
The first successful use of chemical weapons occurred on April 22, 1915, near Ypres, when the Germans sprayed chlorine gas from large cylinders towards trenches held by French colonial troops. -
Air traffic control
the U.S. Army, which installed the first operational two-way radios in planes during the Great War. Technicians could send a radio telegraph over a distance of 140 miles, radio telegraph messages were also exchanged between planes in flight. -
Aircraft Carriers
The first time an airplane was launched from a ship was in 1912. But wasn't considered a true aircraft carrier because it couldn't land on it. British naval designers used a vessel to build a long platform capable of both launching and landing airplanes. To make more room for takeoffs and landings, the airplanes were stored in hangars under the runway. Commander Edward Dunning became the first person to land a plane on a moving ship when he landed a Sopwith Pup on the Furious on August 2, 1917.
