Off course the Indians would target infrastructure and choke points on the Chinese side. No competent military commander would ever dismiss that. The PLA are quite serious on infrastructure and logistics, just like what you recommended. PLA commanders are no fools, they will anticipate these things and have plans for the Indian moves on their vulnerable points. Those PLA military build ups are not just for show. They are there for the defense of China from a rampaging Indian offensive which will include strikes on PLA assets.In a land campaign in that part of the world, the fundamental issue would be logistical and not technological. A large army needs to be supplied to sustain operations.
Just like the Chinese, the Indians would certainly target all Chinese choke points, key infrastructures like bridges et al. Why would the risk of destruction be unique only to the Indian side?
On the logistics war, China can readily supply its troops with locally produced materiel from one of the world's biggest MIC, supported by one of the world's best infrastructure systems. India, on the other hand has a MIC far inferior to South Korea, and has one of Asia's worse infrastructures. Worse still, India needs to import a large portion of their army materiel. They even need to import sleeping bags for god's sake. India's 'sexy munitions' are pretty much all imported. Things such as: M982 Excalibur shells, 155mm artillery shells, Spike missiles, AGM114 Hellfire missiles, Kornet ATGMs, modern 125mm tank rounds, S-400 missiles, etc. We haven't even gone to spare parts and support equipment.
The problem for India is that war with China is not a war on the same scale as Pakistan or Kashmir insurgents where imported 'sexy munitions' always look awesome. Any attack that involves killing PLA troops to grab Chinese territory is not something China can easily forgive. China is a going to give them a full scale conventional war that can drag-on indefinitely. War attrition will punish India many times more than it can punish China. The best historical example is the Falklands war. Argentina have some cool imported weapons that can and did hurt the UK forces. But these weapons were soon expended and towards the end of the war, the Argentinians could just barely sustain the war anymore.
The best case scenario for India is that a small portion of their sexy weapons score some damage on the PLA forces. But that is all they are going to get after a humiliating defeat at the hands of one of the world's real military superpowers.
