With the introduction of new technologies in the industrial era, warfare--along with most other areas of life--went through a major change. During the American Civil War and World War I, advances in transportation, communication, and weaponry changed the way wars were fought. In the decades since World War I, warfare has continued to evolve. This title examines the history of modern warfare and how technology shapes war today, exploring topics such as drone warfare, cyberattacks and social media propaganda, and the role chemical weapons, nuclear weapons, and artificial intelligence play in twenty-first century warfare.
