To destroy the supply logistics and transportation of Indian ground forces up to the LAC, the PLA plans include rocket artillery massed fire-assaults combined with air strikes. To war-game out such a theatre, the PLA conducted its first joint Army-Air Force live-fire exercise on the Qinghai-Tibet plateau simulating the higher altitudes of the Himalayas in 2010.7 Interestingly, the Chinese military transported combat equipment for the exercise using the Qinghai-Tibet railroad, which was a first. The PLA and the PLAAF (PLA Air Force) followed up in 2011 with live-fire exercises on the lower plateau and higher mountains on the Qinghai-Tibet Plateau. For example, the PLAAF assets deployed in the Shigatse air base such as Su-27SKs, Su-27UBKs and J-10s engaged in air sorties in coordination with ground-based radar.8 Again a closer look at the level of PLAAF component in these exercises were limited to roughly platoon sized detachments reflecting the absence of offensive strike and power projection air capabilities in the TAR. But certainly these exercises threw up a lot of smoke and noise intended for the Indians who had their ears pressed to the ground not far away.
The real component of China's operational strategy vis-Ã -vis India at the border are its missiles deployed to the Tibetan vicinity. China replaced its old liquid fueled, nuclear capable CSS-3 intermediate range ballistic missile with "more advanced CSS-5 MRBMs". Intercontinental missiles such as the DF-31 and DF-31A have been deployed by China at Delingha, north of Tibet. China has also deployed the solid fuelled DF-21 in Delingha with a range of 2, 150 kms, which is within striking distance of Delhi (2, 000 kms from Delingha). The DF-21 can be launched from either a 13 or 15 metres diameter pad difficult to detect by satellites because of its mobility. Missiles can also escape detection since they are housed in underground tunnels. Such tunnels exist in Yatung, in the Chumbi valley, close to Sikkim.9
Motorized Capability
Tibet offers a flat surface which augments motorized mobility, which China has exploited fully. China has deployed Main Battle Tanks (MBT) and infantry combat vehicles in Tibet for defensive purposes in case there is a future conflict with India. As well as the mountainous region opposite Northeast India, MBTs have been hauled up and positioned along the LAC. On August 18, 2013, the Tibet Military Command (TMC) of the PLA conducted a wartime river-crossing support drill organized by an engineer regiment in the waters of the Yarlung Tsangpo River. The regiment conducted the drill with new-type heavy pontoon bridge equipment.10
The PLA's ace card is however it's Construction Corps workforce, a highly efficient and disciplined force that can roll out metaled roads during war. Gravel roads on the LAC enable better water drainage during the monsoons as well as avoids Indian radar, which the PLA has taken full advantage of, having the quick capability of converting gravel roads to black topped. The PLA has an edge over the Indian Army at the LAC since it is not tasked to maintain a constant physical vigil, rather content with the usage of networked and remotely-controlled surveillance systems. These surveillance capabilities are augmented with strategically built barren flat ground patches along the LAC to serve as helipads for deploying Rapid Reaction Forces (RRF) whenever required.
The RRF, also called the 'Resolving Emergency Mobile Combat Forces (REMCF)' is the PLA's rapid strike force. The airborne RRF are strategically located within TAR and can be rapidly deployed within 48 hours on the LAC through the network of medium-lift and attack helicopters. The PLA deployment on the LAC opposite Arunachal Pradesh is drawn from the General Army bases in Chengdu and Yunnan. Interestingly, the flanking maneuvers of airborne units combined with jungle warfare training of the PLA units have been strategized to unleash the localized blitzkrieg effect. These efforts are vindicated by dual-use airports near the LAC at Shigatse Pingan and Ngari Gunsa in addition to Lhasa, Nyingchi, and Qamdo airports.11 The surface transportation backbone in the TAR include highways, the railway line and oil pipeline from Gormo to Lhasa, the eastern highway from Chengdu to Lhasa and the western highway running along the LAC though Aksai Chin.
Policy Insights
Three critical policy insights can be drawn from China's intrusions across the LAC and military development in TAR and neighboring areas.
First, China's repeated intrusions are bolstered by its rapid military infrastructure development in its own border regions.
Second, China feels compelled to showcase its military presence to India across the LAC due to its own "vulnerability perception" and lack of political legitimacy in Tibet. China is deeply suspicious about the intentions of the Dalai Lama and the Tibetan-Government in Exile in India. China interprets India's support to the Dalai Lama as a long term Indian strategic objective to free Tibet from China. Hence, any increase in Indian military presence near the LAC is viewed, not only as Indian assertiveness on the border but also connected to plausible Indian plans to provide support to a restive Tibetan population in Tibet.
Third, the US "pivot to Asia" policy has only made China more aggressive with regard to its territorial claims as is seen by its unilateral declaration of an "Air Defence Identification Zone (ADIZ)" over the disputed islands in the East China Sea. The new President Xi Jinping is apparently following an aggressive Chinese posture with regard to its territorial claims. India must therefore remain alert to the fact that escalation across the LAC is likely despite the BDCA. Moreover, India must game out the likely security consequences if China decides to suddenly impose a similar unilateral ADIZ over Arunachal Pradesh.
