Flight Lieutenant Sati Nath Bandopadhyay was commissioned in the Administrative Branch of the Indian Air Force in June, 1965. In April, 1969, he was serving as Security (Counter-Intelligence) Officer at an Operational Wing, where he organized a very effective counter-intelligence cell which had a deterrent effect on enemy agents. He inculcated a high degree of security consciousness amongst personnel of the wing and established excellent liaison with local civil authorities.

In 1970, Flight Lieutenant Bandopadhyay was posted to the same wing as the Station Adjutant. He immediately dedicated himself to his new task and streamlined the administrative set up by working long hours in complete disregard for his personal comfort. During August/September, 1971, he again showed his mettle and contributed significantly in the coordination and implementation of various operational plans. His professional acumen, leadership and devotion to duty have been an inspiring example of those working with him.

Flight Lieutenant Sati Nath Bandopadhyay is awarded the Vishisht Seva Medal for rendering distinguished service of a high order.
