Defending the Himalayan frontier in Ladakh means deploying heavy weapons in tiny posts, often bunkers made of rock fortifications at impossibly high altitudes. Video has emerged of Army jawans deployed in the Kargil-Dras-Batalik sector of Ladakh lugging up an air defence gun weighing more than a ton to an altitude of more than 17,000 feet. The gun - used to target Pak posts along the Line of Control is too heavy to be heli-lifted at those altitudes which is why nothing replaces the physical strength, stamina and determination of Army jawans in lugging up the weapon up near vertical surfaces to get to the post where it is assembled and made ready for action.
