High-altitude troop
deployment CHANDIGARH, Nov 23 As the Army remains entrenched on the inhospitable peaks and snow-clad ridges along the Dras-Kargil axis as an aftermath of Operation Vijay, the Snow and Avalanche Studies Establishment (SASE) has compiled a study of the terrain and avalanche patterns to facilitate incident-free movement and deployment of troops, besides initiating steps to augment its weather forecasting capabilities. The recommendations come in the wake of the government's decision to prioritise high-altitude warfare and man positions along the Line of Control (LoC) in the Dras-Kargil sector throughout the year in an effort to prevent incursions or be caught unawares in the future. SASE Director, Major-Gen S.S. Sharma said that the recce was carried out over a stretch of 150 km along the LoC, with a depth varying from 15 to 20 km inside Indian territory. ''We have sent a detailed report on our observations and recommendations to the Defence Ministry,'' he said. The recommendations, however, are classified. During Operation Vijay, troops had to fight in inclement terrain and adverse climatic conditions. For example, the 16,000 ft high Zanskar Range, which witnessed some of the most decisive battles during the operation, is made up of rocks and loose sand with very steep edges and devoid of any vegetation. This also makes it prone to landslides and avalanches. Winter temperatures in Dras, the second coldest place on the earth after Siberia, plummet to minus 60 degrees Celsius. SASE, an institution under the Defence Research and Development Organisation, is engaged in the study of snow and avalanches along major road-axis in the mountains with a view to enhancing mobility of the armed forces. At present, 11 road-axis and numerous tracks are being monitored for snow and avalanche patterns to forewarn troops as well as the civil population of any impending avalanche danger. SASE has established 22 observatories, eight special snow observatories and two avalanche forecasting centres in various parts of Jammu and Kashmir, besides nine observatories in Siachen Glacier and four in Himachal Pradesh. Some of them are manned by Army personnel. The observations and recommendations thereof sent by SASE would enable formations based in the Kargil Sector to plan their deployments and movements keeping in mind dangers posed by avalanches or landslides, thereby preventing losses in terms of manpower and material. The observations identify danger spots in that area besides determining areas feasible for tactical movement of troops. Certain field tests and risk assessments are also thought to be carried out. SASE is also formulating a standard drill to be adhered to by troops during their movement across the terrain as well as during setting up camp. It is conducting regular classes on safety procedures and precautions to be undertaken by troops and also training troops to identify dangerous situations, rescue and first aid. SASE is also carrying out artificial triggering of avalanches at certain sites in the Kargil Sector to render them safe from avalanches in the near future. Artificial triggering eliminates the avalanche danger on a slope and helps in early opening of the area. While it has been using remote delivery of explosives through mortars and field artillery for some time, SASE has recently introduced a new technique called ''Sprengbahn''. In this method, avalanches are brought down in a controlled manner with the use of explosives. The charge is transported to the avalanche formation zone in very small quantities through pulleys and wire cables. The detonation is ensured about two meters above the snow surface at the desired time and place. The shock waves cause an avalanche in ''batches'' as required. Maj-Gen Sharma said SASE is also setting up more Automatic Weather Stations (AWS) in that area to provide real time advance weather forecasts. ''During Operation Vijay, the weather forecast demand was for three days in advance, which we met by using AWS,'' he added. The AWS collects data
from remote stations using satellite communication links
for transferring the data to base. Quality data can be
assessed in real time at a frequency of one hour. There
are at present eight AWS in Jammu and Kashmir and three
in Siachen. |
