The UPSC plays a significant role in the recruitment of defense personnel through various competitive examinations. It conducts examinations for the Indian Armed Forces, ensuring candidates are evaluated on their aptitude, knowledge, and overall suitability for public service roles. Through the Combined Defence Services Examination (CDSE) and other assessments, UPSC selects candidates for training in military academies. This process emphasizes not only academic achievement but also leadership, character, and strategic thinking skills, which are essential for effective service in the defense sector, ultimately contributing to national security.
