The Type 94 Armored Train was built in 1934. It consisted of 8 cars (Later 9 cars). The trains used two Type 14 10cm AA Gun and two Type 88 75mm AA Guns.This armored train was deployed at 1st Armored Train Unit in Manchuria.

At sea, submarines attacked ships far from port. In order to locate and sink German U-boats, British scientists developed underwater listening devices and underwater explosives called depth charges. Warships became faster and more powerful than ever before and used newly invented radios to communicate effectively. The British naval blockade of Germany, which was made possible by developments in naval technology, brought a total war to civilians. The blockade caused a famine that finally brought about the collapse of Germany and its allies in late 1918. Starvation and malnutrition continued to take the lives of German adults and children for years after the war.

Chemical warfare first appeared when the Germans used poison gas during a surprise attack in Flanders, Belgium, in 1915. At first, gas was just released from large cylinders and carried by the wind into nearby enemy lines. Later, phosgene and other gases were loaded into artillery shells and shot into enemy trenches. The Germans used this weapon the most, realizing that enemy soldiers wearing gas masks did not fight as well. All sides used gas frequently by 1918. Its use was a frightening development that caused its victims a great deal of suffering, if not death.

On the ground new technology was being advanced in the tank. The tank provided the right support for any stalemate in the trenches. his British invention used American-designed caterpillar tracks to move the armored vehicle equipped with machine guns and sometimes light cannon. Tanks worked effectively on firm, dry ground, in spite of their slow speed, mechanical problems, and vulnerability to artillery. Able to crush barbed wire and cross trenches, tanks moved forward through machine gun fire and often terrified German soldiers with their unstoppable approach.

Airplanes, Products of new technology were mostly made of Canvas wood and wire.  At first they were used only to observe enemy troops. As their effectiveness became apparent, both sides shot planes down with artillery from the ground and with rifles, pistols, and machine guns from other planes. In 1916, the Germans armed planes with machine guns that could fire forward without shooting off the fighters’ propellers. The Allies soon armed their airplanes the same way, and war in the air became a deadly business. These light, highly maneuverable fighter planes attacked each other in wild air battles called dogfights. Pilots who were shot down often remained trapped in their falling, burning planes, for they had no parachutes. Airmen at the front did not often live long. Germany also used its fleet of huge dirigibles, or zeppelins, and large bomber planes to drop bombs on British and French cities. Britain retaliated by bombing German cities.

World War 1 started in mostly trenches and dugouts.When attacks were ordered , Allied soldiers went "Over the top" and ran into "No mans land" To get to the enemy trenches, There they'ed have to cut through barbed wire. before they could use rifles, bayonets, pistols, and hand grenades to capture enemy positions. A victory usually meant they had seized only a few hundred yards of shell-torn earth at a terrible cost in lives. Wounded men often lay helpless in the open until they died. Those lucky enough to be rescued still faced horrible sanitary conditions before they could be taken to proper medical facilities. Between attacks,the snipers, artillery, and poison gas caused misery and death.

One of the saddest facts about World War I is that millions died needlessly because military and civilian leaders were slow to adapt their old-fashioned strategies and tactics to the new weapons of 1914. New technology made war more horrible and more complex than ever before. The United States and other countries felt the effects of the war for years afterwards.
