The French infantryman of the First World War entered the war in the famous red trousers, dark blue coat and kepi that had pretty much served him since the Franco-Prussian War.
In 1915 the French government changed the uniform to "Horizon Blue" - a mix of red, white and blue dyes which gave the Poilu a unique appearance on the battlefield. He also sports the first steel helmet of the war, the stylish "Adrian" helmet.
This particular soldier is a "mitrailleur" - a machinegunner. He carries an ammunition crate and his sidearm is a Berthier carbine. His other equipment is standard infantry issue.
