Over the world’s highest battlefield, military personnel faces a lot of problems while moving in the glacier terrains, apart from Cheetal and Cheetah choppers (only allowed for a very few regions) and HAL Dhruv helicopter ,no other vehicles are able to perform. Siachen Glacier presents a unique set of environmental challenges for the human body. These include low oxygen, partial pressure due to reduced barometric pressure at high altitude (HA), extreme cold, high levels of ultraviolet radiation and low levels of humidity. Add to this the constant threat of enemy action, which requires man and machine to be fighting fit and alert 24/7. The extreme, harsh, cruel, body- and mind-numbing conditions at this height. Here, you are at risk of getting frostbite if your bare skin touches the trigger of your gun for more than 15 seconds. A person’s body cannot acclimatise to conditions over 5400 metres. If you stay at this height for long, you lose weight, stop eating and sleeping, and experience memory loss. Speech starts slurring. In short, the body just begins to collapse. In the last 30 years, over 850 soldiers have been martyred at Siachen.
