8. Indian National Defense Academy
Offering training services to cadets in the Army, Navy, and Air Force, India’s National Defense Academy is the world’s first tri-service training academy. The academy boasts a venerable list of decorated alumni, all of whom have either led or been involved in each conflict that India has been involved in since the school’s establishment in 1954. The academy’s admission process features a written exam, along with psychological assessments and a series of rigorous interviews. It is estimated that of the near 4,500,000 applicants that sit for the academy’s written exam, only about 6,000 are invited to interview for entrance into the academy. Of those 6,000, only just over 300 will ultimately be accepted into the academy, meaning that if for no reason other than its near-impossible admission rates, the National Defense Academy in India is one of the toughest military training academies in the world. Those that are accepted undergo demanding academic and physical training, which lasts a total of six terms, each five months in length.
