"This year’s budget allocated Rs 54,500 crore for defence pensions; this would rise by about 40 per cent with the additional Rs 18-20,000 crore needed to meet all the veterans’ demands. India does not count military pensions in the defence budget; even though pensions, like salaries, are a component of manpower costs. The full grant of OROP would raise military pensions to Rs 75,000 crore, only slightly less than the salary bill of Rs 93,216 crore..."
