Squadron Leader Jasbeer Singh was serving as a Flight Commander in a fighter squadron operating in the western sector during the operations against Pakistan.

On 7th September, 1965, Squadron Leader Jasbeer Singh was detailed as the leader of a strike mission against a high-powered Pakistani radar unit near the Gujranwala airfield, which was greatly hampering our air operations. As his formation was about to attack, Squadron Leader Jasbeer Singh observed four enemy Sabre jets approaching. He immediately warned the formation and undaunted by the interception by the enemy aircraft of superior performance and the intense ground fire, he pressed home his attack and inflicted severe damage on the radar Station. In his final attack, when he had to approach the target very low, his aircraft was hit by ground fire and was seen crashing near the target. In this action, Squadron Leader Jasbeer Singh displayed great valour and unflinching devotion to duty, which were in the finest traditions of the Air Force.
