Defense Forces are organized military groups that protect a country from threats and ensure its safety. They are responsible for defending the nation's borders, maintaining peace, and responding to emergencies. The members of these forces, including soldiers, sailors, and airmen, are trained to handle various situations, from combat to disaster relief. In many countries, such as the United States or India, Defense Forces consist of different branches, like the Army, Navy, and Air Force. Each branch has specific roles and responsibilities, working together to safeguard the nation and support international peacekeeping efforts.
