How did new technology increase the number of casualties compared with previous wars?

New technology in warfare, such as advanced weaponry, artillery, and aerial bombardment, significantly increased the lethality and scale of conflicts compared to previous wars. Innovations like machine guns and tanks allowed for more efficient and devastating attacks, while aerial warfare introduced the capacity for widespread destruction from above. Additionally, the use of explosives and chemical weapons in the 20th century led to higher casualty rates among both combatants and civilians. This combination of rapid-fire weaponry and increased firepower contributed to the staggering loss of life seen in modern conflicts.
