Answer:
The use of new technologies such as machine guns, airplanes, submarines, poison gas, and tanks during World War I changed the way wars have been fought in several ways. First, the introduction of machine guns, which could fire hundreds of rounds per minute, made it much harder for soldiers to advance on foot, leading to the development of trench warfare. Second, the use of airplanes allowed armies to conduct reconnaissance, drop bombs, and engage in aerial combat. Third, the use of poison gas caused widespread terror and suffering, and led to the development of gas masks to protect soldiers. Fourth, the use of submarines disrupted supply lines and allowed naval powers to conduct blockades. Finally, the use of tanks allowed armies to break through enemy lines and overcome obstacles, leading to more mobile warfare. These technologies have continued to evolve, with the introduction of drones, cyber warfare, and other advanced weapons changing the nature of modern warfare.
