Brig Sant Singh (1921-2015), whom the freedom fighters in 1971 fondly called “Brigadier Babaji” because of his attire – typical Sikh turban and beard and affectionate attitude, was an officer in the Indian Army. He was one of the six officers of the Indian Army to have been twice decorated with the Maha Vir Chakra, India's second highest war time military decoration. He was one of the Indian officers involved in training the Mukti Bahini, during the Indo-Pakistani War of 1971 and Bangladesh Liberation War.
