Para Commandos are a special forces unit of the Indian Army and considered as elitist of all the soldiers. This force work in special mission such as special operations, direct action, hostage rescue, counter-terrorism, unconventional warfare, special reconnaissance, foreign internal defense, counter-proliferation, counter-insurgency, etc. To become a Para Commandos one has to pass rigorous training after completing their NDA or CDS courses. One can join Para Commandos training after NDA or CDS. As of now you are in class 9, therefore I would advise to join NDA first and after that you can become a part of Para Commandos. For joining NDA you have to first pass class 12 with Physics, Chemistry and Mathematics and clear the written test, SSB and medical exams. For now, you concentrate on your studies and read every subjects thoroughly up to class 12 which will help you to pass the NDA exams.
