National Service is a program where citizens are required to serve in the military or other government roles for a specific period. This service can include training, active duty, or community service, depending on the country's regulations. The goal is to promote civic responsibility and prepare individuals for potential national emergencies. Many countries, such as Singapore and Israel, have implemented National Service to ensure a ready and trained population. Participants often gain valuable skills, discipline, and a sense of teamwork, which can benefit them in their future careers and personal lives.
