Singh, a constable of the forces' 50th battalion, was alone on his observation post and was handling a thermal imager on the intervening night of March 28-29, 2015 when he noticed four armed smugglers on the Pakistani side, opposite BSF post Rattankhurd near Amritsar.
The area is notorious for drugs smuggling from across the border.
Sensing it would take sometime for his colleagues to help him, Singh immediately crawled towards the Indo-Pak fence and challenged the smugglers who were trying to insert a PVC pipe under the ground to pump in drugs.
Once the search of the area was conducted in the morning, it said, the Border Security Force team recovered two bodies of Pak smugglers, an AK series assault rifle, two magazines with 31 live rounds and 12 kg heroin.
