High-altitude warfare
Combat operations conducted above 3,500 metres, where physiological, environmental and tactical conditions impose distinct training requirements.
High-altitude warfare describes combat operations conducted above approximately 3,500 metres elevation, where the combined effects of reduced oxygen, low temperatures and steep terrain impose conditions that fundamentally change tactical considerations. The Indian Army operates more high-altitude terrain than any other land force on earth — Siachen (the highest battlefield in the world), the Ladakh sector, Sikkim, Arunachal Pradesh and Tawang.
The High Altitude Warfare School (HAWS) at Gulmarg, established in 1948, is the institutional anchor for Indian high-altitude doctrine. HAWS courses train officers and soldiers in glacier movement, cold-weather injury management, high-altitude tactical drills and acclimatisation protocols.
Synthetic mountain training is a force-multiplier for the long flat space between HAWS courses, where most of the Army actually trains. Pre-rotation rehearsal on terrain digitally modelled on the destination sector — Galwan-pattern, Tawang-pattern, Demchok-pattern — allows units to compound coordination reps before the deployment itself. SHAURYA-SIM and NETRA-SIM compose against this requirement.
