China is deploying more advanced technology to overcome the challenges of high-altitude warfare and shorten supply lines for troops on the country’s contested border with India . According to state media, the People’s Liberation Army has been testing various new weapons, including a new infantry rocket launcher with upgraded anti-tank and anti-bunker capacity. The rocket launcher was tested at “an average altitude of more than 4,000 metres (13,100 feet)” in a live-fire drill by a unit from the 77th Group Army under the PLA’s Western Theatre Command, according to a report on China Central Television on Sunday. Shanghai-based news site Eastday.com said the rocket launcher was the new and lighter Type-11 93mm, which could fire various types of shells. “The Type-11 93mm infantry rocket launcher has a larger calibre than the previous 80mm rocket launcher. With a maximum range of 850 metres and better multi-purpose ammunition, the rocket launcher can provide important and flexible backup firepower for light infantry units,” the report said. China-India border dispute: armed parachute drills by elite PLA forces point to military build-up The Tibet military command’s official social media account also announced on Wednesday that helipads had been built at its general hospital in the regional capital Lhasa, and the facility was ready to take wounded flown in on helicopters. The command said helicopter transport would cut the time needed to ferry wounded troops from the front line with India, with ambulances taking at least six hours to travel from Shigatse – the city closest to the border – to Lhasa. Wu Qianjin, director of the hospital’s medical services department, was quoted as saying that such new facilities were to ensure “seamless connection from the hospital to the border post, training ground and other venues”. CCTV has also reported on an array of new military equipment for use in hostile environments, including an all-terrain crawler to transfer wounded, and drones, robots, new transporters to deliver rations, ammunition and fuel to the front line. In one report, a logistics unit deployed a swarm of drones to send hot meals troops in a drill to practise overcoming roadblocks. In addition to the troops in Tibet, the PLA has units stationed in Xinjiang, Yunnan and Sichuan provinces that can also be deployed to the border with India, but they need to travel thousands of kilometres to reach the battlefield. Observers said the challenges of long transport lines and heavy equipment needs could only be mitigated by wide application of new military technology. “Many of Chinese equipment for high-altitude warfare have been developed in China and tested on the plateau, but much of India’s equipment has been bought from the United State and not tested in warfare above 5,000 metres,” said Song Zhongping, a Hong Kong-based military analyst.
