i am doing my electronics and this is my final year. Generally there were few things i would like to know about the military.. the only entrance i know of when i was in school was NDA and gradually in college i got to know that you can join the armed forces through CDSe. i have this friend we grew up together,and even at the early stage during school we always dreamed of being in the armed forces.. we both had finished school together but his stream was commerce.. right now we both do want to appear for the entrances however he believes that his chances are very slim. he isnt a graduate as he got some few back papers he has to appear for.he is 23 years old,what we want to know is,can he still appear for the NDA? and are the escalations true that if a person has body art(tattoos),he is not eligible for the indian armed forces inspite of being medically fit as its permitted in some countries..
