On the 40th anniversary of Operation Meghdoot, Indian Army officials explain some major initiatives undertaken in the Siachen Glacier area in the recent past by the Indian defence forces including the induction of heavy-lift helicopters and logistic drones that have vastly improved the supply of essentials to personnel deployed in posts that are cut off especially in winters. The availability of special clothing, mountaineering equipment, and advanced rations has enhanced the ability of soldiers to withstand the harsh conditions of the world's coldest battlefield. Gadgets such as Pocket Weather Trackers with each soldier provide timely updates on the weather and warn them about possible avalanches.
