Military force refers to the organized use of armed personnel and equipment by a nation or group to achieve specific objectives, such as defense, deterrence, or the enforcement of laws. It can include various branches, such as the Army, Navy, and Air Force, each specializing in different types of operations. The application of military force can range from peacekeeping missions to full-scale warfare. It is often guided by national policies and international laws, including treaties and conventions that regulate the conduct of armed conflict and protect civilians, such as the Geneva Conventions.
