How did new technology in World War 1 change the way battles were fought?

New technology in World War I, including machine guns, tanks, and airplanes, fundamentally altered battle strategies and tactics. The introduction of machine guns led to trench warfare, creating a stalemate on the Western Front where soldiers faced devastating firepower. Tanks provided mobility and the ability to break through entrenched positions, while airplanes introduced aerial reconnaissance and bombing capabilities. This technological shift made battles more destructive and increased the scale and complexity of warfare.
