What type of warefare was common during world war 1?

World War I was characterized by trench warfare, where opposing armies faced each other in fortified positions, creating a stalemate on the Western Front. Soldiers lived in unsanitary conditions in long, narrow trenches, leading to high casualties from battles and disease. Additionally, technological advancements introduced new forms of warfare, including machine guns, artillery, tanks, and chemical weapons, which further intensified the brutality of combat. This combination of static defense and devastating firepower defined the conflict and its high death toll.
