World War I (1914-1918)
By the time of World War I, technology was a key component to winning the war. The use of the Maxim Gun, a self-powered machine gun, increased the number of casualties in the war since it increased the number of bullets fired. The British also introduced artillery tanks into the war, allowing troops to fire upon their enemies at a closer range. To protect themselves from powerful artillery attacks, both sides of the war used trench warfare.
