Final answer:
The first time a cyberattack coincided with a military campaign was during the Russo-Georgian War in 2008, marking a significant shift in the nature of modern warfare.
Step-by-step explanation:
The first time in history that a cyberattack was synchronized with a military campaign was during the Russo-Georgian War of August 2008. Although World War I was the first mechanized war and witnessed many technological advances in warfare, it did not involve cyber warfare. Similarly, the Ukrainian Revolution and the American Civil War occurred long before the advent of cyber technologies. The Russo-Georgian War, however, combined traditional military action with cyber-attacks targeted against Georgian national communication and information systems, marking a new era of hybrid warfare where both digital and physical battlegrounds are crucial.
On August 8, 2008, Russia initiated an invasion of Georgia, representing the first war of the 21st century in Europe and the first instance since World War II that a major European power had invaded another sovereign European nation. The conflict escalated with a Russian aerial bombardment, which the Georgians responded to with artillery, but ultimately they could not repel the invasion.
