My inputs suggest that Pay Band-4 (Rs 37400 - 67000) is finally through albeit with a Grade Pay of Rs 8000. All Lt Cols at 13 years of service are to be upgraded to PB-4.
Lt Cols, Wg Cdrs (IAF) and Cdrs (IN) have been placed higher than the grade of Deputy Secy to Govt of India (erstwhile Rs 12000-16500 scale / now Pay Band-3 with Grade Pay Rs 7600) but lower than Directors to Govt of India (Pay Band-4 with Grade Pay Rs 8700).
The minimum pension of Lt Cols who retired prior to 2006 is however likely to be jacked up above Directors GoI.
The basic minimum pension of pre-6th CPC retirees of the rank of Lt Col is expected to be Rs 25700. Basic pension of pre-6th CPC Directors (GoI) is Rs 23050.
Again, I still would suggest readers to take the above with a pinch of salt till the final official announcement.
