Hi Pritee,

Defence Navy is the place where the individual works for his or her Nation. In this individual had to serve for his Nation by keeping an eye over the sea and protecting the country through Enemies on waterways. There are different works in Navy and in different fields like an engineer for moving the ship or the submarine. For entering into this field you need to study and clear the exam for this particular field and there are different exams for Navy like NDA, CDS etc. In this field you need to be in submarine or on ship for 24 hours with heavily armed weapons in submarine.

I hope your question has been answered properly.

All the best for your future!
