World War I

World War I was a Human conflict.

War
World War I was the first human conflict in which flamethrowers were used. Trench warfare was common during the war.

War's end
By 1918, forces were told that the war would end on November 11. However, no orders were given about what would happen prior to that. This resulted in some forces standing down and others continuing to fight. On Armistice Day itself, the fighting was more intense than D-Day.

Aftermath
Following the conflict, flamethrowers changed very little over the centuries.
