ITBP jawans are known to protect the country in the coldest temperatures. Currently, they guard the second highest outpost in the world OP Dorjila Post at 18,750 feet where temperatures go down to -35 degree Celsius.

We can't even imagine functioning at these temperatures. Recently, a video of an ITBP Commandant doing push-ups at 17,500 feet in Ladakh surfaced on social media.

Ratan Singh Sonal, a 55-year-old ITBP Commandant, did 65 push-ups as the temperatures went down to -30 degrees Celsius.

Netizens felt proud of his act.

Just last week, Ratan Singh led a team of 6 mountaineers to the peak of Mount Karzok Kangri. This as the first-ever ascent of the 20,177 feet high mountain. The minimum temperature at the peak was - 40 degree Celsius.

Salute to his dedication.
