There are many Indians who still want to join Defence services but due to lack of awareness they miss out. I remember during Kargil war people standing in long queue outside Command office in Kolkata for a chance to die for our motherland. I think similiar situation in all other cities as well. If all these people are recruited and send to LOC Pakistsn will not dare think of coming close to LOC. Also at the age of 18-20 decisions are mostly taken by parents who want there children to excel in corporate world. Even who want to join Defence cannot do so because of parents pressure. Defence could think of recruiting people even after attaining 30 or 35years. These people are much more mature and are not under pressure by any quarters.
