Not necessarily..China already have existing structure for their troop mobilization..even if we destroyed few link or rail and road we can easily repair and use them...the Highway 219 which passes through along the Indian border ..and we have many mountain passes with Tibet which were traditional route for millennium ..those are currently closed but in pleasant situation we will reopen them...Sela in Arunachal ..Lanak la -Chang-chemno vally route in Ladakh...Nathu la to Chumbi valley etc ..
If China can maintain troop there so we can...Logistics would't be the biggest question ..the question is how to dislodge the CCP from Tibet..making Tibet our protectorate is't primary objective..Creating buffer betn CCP and India is the main objective...
Yes, we can utilize those bridges, once we take over Tibet, but that is an overkill from logistics point of view. Every single day, tons of food and other materials need to be transported to keep our Personnel's healthy and sound. It is not feasible, long term. China is maintaining troops by means of importing food and materials as I have already told above, but for them it is easy because of the railway link, but there is no railway link towards India, we need to start building one, and that would take a couple of years. Dislodging PLA can be left to IAF, and a portion of our ground forces, but we have to think after that.
in Tibetan plateau there are't much tunnel and bridges , the weak link of their supply are in the northern and eastern entrance of Tibetan plateau...these are mountainous region like our Arunachal and UK along with River valley where China building record high bridges...but they are very deep inside china , so deep that they are in different military district than Indo-China border.it would be a hell of a task for air-force to breech and destroy those bridges
Agreed, we can't destroy those, what we need to do is destroy those near Tibet, not the ones in mainland China, if you destroy the ones in Tibet, that would get the work done. There is a lot of distance from China to Tibet, thus the transport infra, once we destroy 100s of kms of infra in Tibet, their transportation link is severed, and they can't attack Tibet except via air, and that can be left to IAF to manage them.
