Naik Nirbhay Singh Sisodiya, AC (1 May 1958 – 6 June 1984) was an Indian military Non Commissioned Officer (NCO) with the 15th Battalion of the Kumaon Regiment. For his bravery, he was posthumously awarded the Ashoka Chakra, the highest peacetime military decoration in India on 26 January 1985. During the Operation Blue Star on 6 June 1984, he provided cover for his company commander from heavy firing by the Sikh militants using medium machine guns. Sensing danger to his company from a light machine gun in a pot hole, Singh charged towards the gun. Although he suffered bullet shots to his legs, he crawled to reach the pot hole and lobbed a grenade into the basement, but exposed himself to heavy firing and succumbed to his injuries.
