Lt. Gen. Sanjiv Rai (Retd.), former GOC Chetak Corps and Military Secretary to the President of India recalls the role of the Special Frontier Force (SFF) to push back China beyond Pangong Lake in the strategic heights of Ladakh. The SFF is an elite paramilitary unit of the Indian Army formed almost entirely with Tibetans. He said their skill of living off the land longer than anyone else gives them an edge at the icy heights and is the reason why they are so reverred.
