Hello Hari,
Yes, defense quota is there in admission.
Candidates whose parents are in Navy or army have seats reserved for them.
Defense or Ex-servicemen quota is there in all states and central seats for MBBS entrance. But is very less maybe 1 to 3% only. Seats will be allotted for that quota and they will call them separately after general counseling is over.
Check the official website of the exam for the exact number of seats and procedure.
Good luck!
