India has presently 22.56 lakh veterans in the country. The health behaviour of these veterans while entering the Army and during service is very good, but what is their health behaviour after retirement is often ignored. In this study, an attempt has been made to enquire about the health behaviour of Indian Army veterans along with their socio-economic background and service profile. The data for the present study have been collected by a structured interview schedule where a total of 200 respondents have been interviewed. The respondents who have been selected using snowball sampling are non-commissioned and junior commissioned officers. The data have been analyzed through statistical techniques like coding, grouping, classification, tabulation, etc. Most Indian Army Veterans reported good health behaviour after retirement. However, several veterans described challenges in maintaining their health behaviour due to new commitments and limited facilities in civil society. Veterans refer to persons who have served in any rank in the Indian Army and have retired from such service. In addition to defence and security, most of the activities done in military service lead to the good health of soldiers. However, there are still some actions like smoking, use of tobacco, alcohol, etc. that negatively affect health in military service. But despite all this, there are many such activities like good nutritious food, physical exercise, routine, etc., which lead a person engaged in military service towards good health behaviour
