Poison Gas: It was first used by the German army at the Battle of Ypres in 1995. The gas caused a burning sensation in throat and chest pains. There were many different kind of poison gases that both sides experienced by the end of the war. To use the gas, the weather must be right, especially the wind. Both sides used this weapon to weaken the other side's army without using violence or violent explosion. It was easy to fire into trenches in shells and took a period of time to cause the effect.
Tank: It was used by firs time at the Battle of the Somme. Its maximum speed was 3mph but could not vross the trenches but by the end of the war, it could cross and carry 10 men, reaching the speed of 4mph. The British's adavantages from using the weapon first was the tank's protective metal kept the men inside from falling victim to the onslaught of enemy machine guns. The heavy tank crushed everything in sight, including the dangerous barbed wire guarding the trenches.
Grenades: The Germans were the first ones to use this weapon but both sides eventually used it. It has numerous models, easy to carry into the war. It was a small bomb that can be thrown by hand. The grenadiers raced down the trenches and threw grenades into each dugout they passed. Even though it did not create a big explosion but it was enough to injure many soldiers within areas or caused deaths. Both sides saw the advantages of this weapon, they designed explosive grenades to detonate after impact or after a set amount of time.
Mortars: It was an indirect fire weapon that fires explosive projectiles known as (mortar) bombs at low velocities, short ranges and high-arcing ballistic trajectories. It was portable and could fire unexposed from the bottom of a trench, droppping their shells into the enemy trenches. It was essentially hollow tubes angled greater than 45 degrees. It was used by the British to help transmit the forces/loads through the bricks evenly so is a great advantage in load bearing work. Mortar is relatively stable in all weathers providing wind and weather protection to the wall. During the trench warfare, many weapons were introduced from both sides Allie and Central Powers. The effectiveness increased faster when many deaths were caused, over 8.5 million
