Modern World Wars have seen a dramatic transformation in military tactics and strategies adopted by countries around the world. Since the mid-20th century, technology and geopolitical dynamics have forced armed forces to make significant changes in the way they plan and execute military operations. One of the biggest changes in military tactics is the use of advanced technology. The development of precision weapons, such as cruise missiles and drones, has changed the way combat is fought. This weapon allows more accurate attacks with a lower risk of collateral damage. For example, during the conflicts in the Middle East, the use of drones by the US and their allies enabled reconnaissance and attack missions without sending troops into battle. Apart from technology, war strategy has also evolved. The concept of asymmetric warfare is becoming increasingly important, where a weaker side uses unconventional methods to fight a greater power. A clear example is the guerrilla tactics applied by non-state groups in various parts of the world. This represented a change in the way wars were fought, where the application of intelligent tactics and local knowledge could offset an opponent’s technological superiority. Modern world wars also demonstrate the importance of information warfare. The influence of social media in shaping public opinion and strengthening propaganda is inevitable. This power is not only used to improve one’s image, but also to damage the reputation of one’s enemies. For example, during the conflict in Ukraine, disinformation spread via online platforms became an important weapon in influencing international perceptions. Multinational collaboration is also a hallmark of modern warfare. Alliances like NATO show how countries can come together to respond to common threats. Joint operations and joint exercises are frequently conducted to increase interoperability and effectiveness on the battlefield. The success of missions such as the intervention in Libya has demonstrated the importance of international cooperation in countering human rights violations and maintaining stability. Modern world war also demands strategic thinking based on data. The use of big data and analytics enables military commanders to make more timely and informed decisions. By analyzing patterns and trends in enemy behavior, armed forces can devise better strategies and anticipate enemy moves. It cannot be denied that cyber security has become a new arena in modern world war. With increasing reliance on information technology, cyber attacks have entered the domain of military conflict. Countries must now consider protecting their critical infrastructure from attacks that could disrupt military systems and civil society. Therefore, the evolution of military tactics and strategy in modern world wars illustrates the ever-growing complexity of international conflict. By combining technology, international collaboration, and information warfare scenarios, armed forces must remain adaptive and innovative to meet the challenges before them.
