On 28 June 1999 during 'Operation Vijay', Captain Sumeet Roy was the second-in command of Delta Company which was assigned to capture Point 4700 in the Drass sector. Captain Roy was tasked to capture the observation post of the enemy. He set out with a section and at 2330 hours, following a covered approach, reached just below the observation post. He kept observing the movement of the enemy in the observation post till 0200 hours on 29 June 1999. In a daredevil move and with total disregard to his personal safety, he climbed up the cliff and reached the observation post and totally surprised the enemy. In a fierce hand-to-hand fight he killed both the enemy sentries. There was panic in the enemy ranks and the enemy fled leaving behind huge quantity of arms and ammunition. However, he later succumbed to injuries sustained due to the enemy artillery firing on 03 July 1999.

Captain Sumeet Roy displayed exemplary leadership, indomitable spirit, extraordinary courage and valour in the face of the enemy contributing immensely towards the capture of point 4700.
