Mortars were smaller tubes that shoot shells. They were useful since they were smaller and could be used in the trenches. The picture above shows the Germans with their mortar that they used in 1914. The mortar was used to shoot at the other trenches where you think there might be artillery or other soldiers. Overal the mortars were a very effective weapon that was used in trench warfare.
Artillery was one of the most powerful weapons in the war. In WW1 there was light and heavy artillery. Light Artillery like the 10.5cm leFH 16 was used all through WWI. Also, heavy artillery like 42cm/L12 also nicknamed the big bertha was used in the war. A picture of the big bertha is shown above. This was a very effective heavy artillery weapon that was able to destroy the allied forces in its first use by the Germans against Belgium on August 12th 1914. another heavy artillery was the Paris gun that was shot towards Paris. This weapon did do not affect the allied soldiers directly since it hit civilians in Paris. The Paris gun had to be attached to a railway track and could shoot 70 miles.
Rifles were the most commonly used weapon in the war. Every soldier on both sides of the war used rifles in battle. Due to everyone having rifles and other dangers like machine guns and artillery as a soldier you would have to stay in your trench. In close combat rifles used in WWI had bayonets attached to them so you could thrust and stab your rifle at the opposing side. There were many rifles used in the war and most had to be reloaded after one shot. Overal a rifle was the most crucial weapon a soldier in WWI would have with them.
Zeppelins were giant hydrogen-filled airships. They were used by both sides of the war. They were used more by the Germans. They had to fly very high so they could not be seen by planes. They could fly higher and farther than planes and were to be used for bombing. A soldier dropping the bombs would have trouble since you would not be able to see where you were dropping them. They did not do much damage but effectively scared the people they were bombing.
Tanks were first used in WWI. They were armoured and weaponized vehicles used in WWI. Tanks like the British Mark V tank in the picture above where very useful and effective in the War. Tanks could easily roll over barbed wire and were not susceptible to rifles or machine guns. Due to the tank treads, they could roll over the rough and uneasy terrain but certain terrain the tanks could not go over and they would get stuck. Tanks were a replacement for calvary which could be easily taken down by machine guns.
Poison Gas was a very dangerous weapon in WWI. The canisters showed above-held mustard gas. Even though chemical weapons were illegal to use in the war it was first effectively used by the Germans in the second battle of Ypres. The Germans used chlorine gas against the allies and killed many of them. Poisons like chlorine and mustard gas were very dangerous because they could burn your skin eyes and lungs and kill the person who you are attacking and also the person using it. In the war gas mask were later developed to help stop being killed by gas attacks. Even if you were not killed by the poison gas it could kill a soldier later in life or prevent them from having a job due to injuries sustained from the gas.
The machine gun was by far the most useful weapon in trench warfare. Machineguns could shoot between 400 to 600 rounds per minute. They were very efficient and effective in trench warfare and you could easily mow down your enemies. This weapon was first used by the Germans against the British. It was also used in the battle of the Somme and on the first day the British had 57000 casualties. the machine gun shown in the picture is the German MG 08 machine gun.
