An individual with 10 years of service in the Indian Army was discharged under the OSL (deserter) category and is not a pensioner. They are inquiring whether they can apply for government jobs using the Ex-Servicemen (ESM) category reservation, given they are 33 years old and seek age relaxation. Based on previous clarifications, being a deserter and not a pensioner generally disqualifies one from being classified as an Ex-Servicemen for reservation purposes.
