Military refers to the organized armed forces of a country, responsible for defense and warfare. It encompasses various branches, including the army, navy, air force, and sometimes marines and coast guard. The military’s primary purpose is to protect a nation’s sovereignty and security, engage in combat during warfare, conduct peacekeeping operations, and assist in humanitarian efforts.

Military organizations are typically structured hierarchically and operate under strict discipline and regulations. Members of the military, known as service members or personnel, undergo rigorous training to prepare for a range of operations, including combat, logistics, intelligence gathering, and support roles.

In addition to combat roles, the military plays a significant role in national policy, diplomacy, and disaster response. Military technology, strategy, and history are studied in academic and professional settings, emphasizing their impact on global relations and security dynamics.
