Naib Subedar Bana Singh, born in Kadyal, Jammu on 6 January 1949, was enrolled in the Indian Army on 6 January 1969 into the Jammu & Kashmir Light Infantry (JAK LI). During June 1987, the 8 JAK LI, was deployed in the Siachen area. It was then found that a large number of Pakistani infiltrators had intruded in the Siachen Glacier. The ejection of these infiltrators was considered difficult but necessary and a special task force was, constituted for the purpose. Naib Subedar Singh volunteered to join this force.

The Pakistani intrusion had taken place at a height of 6500 metres. The enemy post was virtually an impregnable glacier fortress with ice walls, 457 metres high, on either side. Naib Subedar Bana Singh led his men through an extremely difficult and hazardous route. He inspired them by his courage and leadership. He and his men crawled and closed in on the adversary. Lobbing hand-grenades, charging with a bayonet and moving from trench to trench, he cleared the post of all intruders. Naib Subedar Bana Singh was awarded the Param Vir Chakra, the highest wartime gallantry medal, for conspicuous bravery and leadership under most adverse conditions.
