Hello there! 

Greetings! 

If you are asking about some benefit which you will get during recruitment into indian army then sorry to tell you but you will not get any benefit during recruitment just because you pursued defence studies but it will be highly useful for you once you get into indian army.

Defence and security issues are a focus for countries around the globe, including India. Various opportunities are available to those who opt for this sector. You can work for the government or private security firms. The DRDO and the IDSA in India are places to explore. You can also opt to work in war-affected or terrorist risk areas. At the state level, especially those with International boundaries may require your expertise for strategic planning. 

Thankyou
