Armed forces are organized military groups responsible for defending a country and its interests. They typically include branches such as the Army, Navy, Air Force, and sometimes Marines. These forces are trained to respond to threats, conduct operations, and maintain peace and security. Members of the armed forces undergo rigorous training to prepare for various situations, including combat and humanitarian missions. They may also assist in disaster relief efforts and support international peacekeeping operations. The armed forces play a crucial role in national defense and are often called upon during emergencies or conflicts.
