How did the different technologies World War 1 lead to death to so many soldiers?

World War I saw the introduction of advanced technologies such as machine guns, tanks, artillery, and chemical weapons, which significantly increased the lethality of warfare. The machine gun, in particular, allowed for rapid-fire capabilities that devastated infantry charges, while heavy artillery and aerial bombardments caused massive casualties from a distance. Additionally, the use of poison gas introduced a new, terrifying element to combat, leading to painful injuries and deaths. The combination of these technologies, along with trench warfare, created a brutal environment that resulted in unprecedented loss of life among soldiers.
