In the early days of World War 1, warfare is still based on ideas and ideals of 19th century generals. The technological progress during industrialisation clashes with obsolete war tactics (Plan XVII). Tens of thousands of soldiers lose their lives in carnage at the Western Front. The French Army marches into battle in bright uniforms, where the German Army awaits them with machine guns. Artillery already shows how brutal and effective it's going to be during the rest of World War 1.
