From 1990 to 1992, he was commanding the prestigious 4 Corps in Assam. He had the responsibility of wiping out ULFA insurgency with over 1 lakh troops and Police Force, under my command. Appropriate civil support and funds were also placed at his disposal. Macro perception of "Counter Insurgency", involves Anti-militant Operation" and "Winning over the local population. By launching two successive operations, viz., "Bajrang" and "Rhino", I smashed the ULFA insurgency in less than three months, creating a record in counter_insurgency operations. For outstanding qualities of leadership, dynamism and courage, he was awarded the coveted "Param Vishist Seva Medal (PVSM)". The success of the operations came because of close Co-ordination with the various agencies involved in bringing the law and order situation under control in Assam. Since the Chief Minister had made him the Chairman of the Apex Body at Guwahati, he was masterminding co-ordinated actions between State Administration, Para-military Forces, Political leaders of various regions and the powerful regional media of the State of Assam. This required tact, understanding and managerial skills of a very high order. Because of this intimate them work with which I was involved, the State of Assam recognized my services by giving me the "Governor's Gold Medal" for exceptional services rendered to the State.

Also, during his command of 4 Corps, to win the hearts of aggrieved people of Assam, a major welfare programme aimed at providing assistance to the poor and under-privileged people in far flung areas was undertaken. Activities like medical care, construction of sheds, adult education, digging of tube wells, constructions of roads were undertaken by the Army under my direct supervision of the GOC 4 Corps. This act was highly commended by the State Government and the media. This operation was conceived by him to wipe out the root cause of insurgency support, and to project an image of a Nation that cares.

He was posted as Director General, Combat Vehicles (DGCV) in 1992 and assigned the task of salvaging the still born Main Battle Tank (MBT) project which had been struggling to produce Arjun Tank for the past 20 years. Within a matter of six months, this tank was given an operational shape and the Hon'ble Defence Minister dedicated MBT Arjun to the Nation on 28th February 1993. It was a momentous occasion for DRDO. After the successful missile programme, this was their major achievement. He was again recommended for the award of PVSM, but since there was no past precedence for awarding PVSM for the second time, it could not be awarded. The Scientific Advisor to Raksha Mantri Dr. APJ Abdul Kalam, having recognized his talent and work created a new appointment in DRDO for him and on retirement, he was inducted as Chief Controller R&D (Land System). On induction as CC R&D, he was given another challenging task of modernizing the existing fleet of T -72 MI Tanks. This project had been with the Army for the past eight years and had not progressed much. He achieved in a record time of 6 months and that too within the resources of the DRDO.
