SUBMARINER SANDEEP GUPTA

Hi,

 

With your blessings and best wishes, I am honoured to be featured on the cover page of one of India’s leading magazine “FAMES INDIA”.

 

DDA’s dedicated work towards guiding the youth in building careers in the Indian Armed Forces, Merchant Navy, and through various foundation courses has been recognised and appreciated by the esteemed organisation behind this publication.

 

This honour continues to motivate and inspire me to keep mentoring the younger generation with even greater passion and purpose.

 

My ultimate aim is that one day, some of the DDA Diamonds will rise to become the Chief of the Army, Navy, or Air Force ✌️✌️

 

I would like to express my heartfelt gratitude to my family, relatives, friends, batchmates, Team DDA, all my students and their parents, and last but certainly not least, the Indian Navy—without whose support, this journey would not have been possible.

 

Jai Hind!

Sandeep Sir 🙏🙏❤️❤️
