Respected sir,
I am santosh b patil a son of an ex-serviceman who served 17 years in indian army as a soldier, sir i want to know that why only indian army select youngsters in age between 19 & 20 after that there are so many like me, who thinks to join indian army with a gud position like leutenent or other post but indian army allows only 10+2 candidate to join for nda exam it means for 19 age or 20 age youngsters, basically in that age some o[censored]s not even able to think what to do in future after some diploma some of youngsters think to join indian army with full of confidence but indian army doesn't offer the opportunity to such people, the indian army offer post after some degree that s also by applying upsc exam but some o[censored]s want to join as like leutenent nd other post,
I hardly request indian army to allow such diploma candidates and after 21 age students to join indian army even they also want to join & serve for nation. jai hind.

Thanking you,
Your's faithfully
Santosh b patil
