Defence Forces are organized military groups responsible for protecting a nation's sovereignty and interests. They typically consist of various branches, such as the Army, Navy, and Air Force, each specializing in different aspects of defense. Their primary roles include national security, peacekeeping, and responding to emergencies. In addition to combat roles, Defence Forces often engage in humanitarian missions, disaster relief, and training exercises with allied nations. They play a crucial role in maintaining stability and can be called upon during crises to support civil authorities and assist in recovery efforts.
