Ex-servicemen are entitled to get age relaxation for appointment to any vacancy in Central civil services/posts, whether reserved or not. Ex-servicemen who have already secured employment under the Central Government are entitled to the benefit of age relaxation as prescribed for securing another employment in a higher grade or cadre under the Central Government.
