Poison Gas

Gas was introduced by the Germans, but used by both sides. Some gases caused blindness, severe blisters, or death by choking. To protect themselves from these poisonous gases, soldiers wore masks to protect themselves. Though these poisonous gases were able to kill soldiers, they were meant to distract the enemy so that the enemies were unable to defend themselves. The invention of poisonous gas impacted warfare greatly because it was a new secret weapon that could go off whenever.

Machine Gun

Machine gun was improved greatly by World War I and was able to take out waves of attackers due to its ability to fire ammunition automatically. When being used, the machine gun required a gun crew of 4 to 6 operators. Though it was an automatic gun, the system overheated guickly and needed to be cooled down. Despite having to be cooled down, the machine gun greatly impact warfare because it was able to be used as a powerful defense mechanism. As a result, the machine gun made it difficult for forces to advance, and gave the upper hand to the side using the machine gun.  


The tank was introduced by the British in 1916 at the Battle of the Somme, and was designed to be able to maneuver through trenches and other uneven land. The tank's chain tracks as wheels enabled the tank to do so. In addition, the tank held as many as 6 soldiers which allowed soldiers to advance safely without being shot. Overall, due to the mobility and sturdiness of the tank, the tank was able to help get rid of the stalemate and advance troops further.


The Germans introduced the submarine in 1914 as an effective warship due to its primary weapon—the torpedo. The torpedo was basically just a missile under water, but it was very effective because the submarines helped the Germans take out the British navy, which was Britain's best asset. All in all, the submarine was important because it was a new weapon that was able to hit ships underwater.
