Another VIF article on Chinese military deployment in Tibet:
The VIF link gives a break up of the larges scale military deployment of PLAAF, PLA and Strategic assets in Tibet. The 03 Brigades and 01 Division plus ancillaries are also mentioned.
Something that caught my attention in the article:
China also recently flight-tested its latest Z-18 (White Heron) military transport helicopter developed by the Changhe Aircraft Industry Group (CAIG) in Tibet when it broke a record by attaining an altitude of 9000 metres and flying above Mount Everest. Capable of carrying 27 passengers with a 2-man crew, the Z-18 is the second Chinese military helicopter after the Sikorsky S-70C, that can operate in the high-altitude Qinghai-Tibet Plateau.
Similarly regiments of the Second Artillery, Rocket Artillery and Armoured Brigade deployed in the Tibetan Plateau conduct regular training and ‘live-fire’ exercises under conditions of ‘informatisation’. On July 28, 2015 a Regiment of the Second Artillery conducted a live-firing exercise with "new artillery guns" at a location in the Tibet Plateau and at heights between [b]3700 metres and 4800 metres.[/b] The troops “prepared an environment for actual war situations” and conducted an "exercise to address the problems of Combat unit mechanical failure, electrical problems, battle damage repair, and to enhance the soldiers ability in battlefield command and also in practical use of equipments and to support the proper use of artillery. They also carried along 300 electrical equipments".
Apparently expanding the scope of the exercise, the PLA General Logistics Department (GLD) started its materials and POLs supply drill codenamed "Supply Action-2015" in the Tibet Autonomous Region on August 8, 2015. Separately, China's official news agency Xinhua reported on August 10, 2015, that the PLA Chengdu Military Area Command started a joint military drill code-named "Joint Action-2015D" in late July 2015 that entered its 'live fire' stage on August 10, 2015 "in a plateau area in southwest China's Sichuan Province". It disclosed this would be the first of five similar drills that will involve a total of more than 140,000 soldiers from over 140 PLA regiments of various types.
