Hello sir,

There is obviously an opportunity for you to sit for the examination, provided the maximum age concession of 5 years for ex-servicemen  who have rendered a minimum of 5 years of military service (according to the Re-employment in Central Civil Services and Posts Rules, 1979). Ex-servicemen has no such bar on number of attempts till they reach the age limit. There are similar other relaxations for candidates of backward classes as well.

Hope it helps. Good luck !
