Why Defence Is a Top Career Choice for Tamil Nadu Students
The Indian Armed Forces offer a combination of prestige, adventure, job security, early promotion, and strong pay and benefits that few other careers can match at age 19–20. Tamil Nadu has a proud history with the Indian Army — the Madras Regiment, one of the oldest in the Indian Army, has its home at St. Thomas Mount, Chennai.
Joining the Forces after Class 12 through NDA means you graduate as a commissioned officer at 21, with a B.Sc degree from Jawaharlal Nehru University (JNU) — well before most peers finish their regular graduation.

NDA (National Defence Academy) at Khadakwasla, Pune is the joint training academy for the three services. After 3 years at NDA (6 semesters), you proceed to service-specific academies for further training before commissioning.
