This is especially true because of the heavy use of mounted machine guns that both sides of the war used. These guns would tear through enemies easily. This style of warfare was also vulnerable to bombings and gas attacks, as the soldiers were stuck in the trenches and the heavy poisonous gasses would sink into the trenches.
