Are you serious? You actually expect the Indians to survive the massive Chinese firepower just because a senior Indian member says so? Bipin Rawat, the number one guy in the IA, says the Indian military can withstand a 2.5 front war and you are just going to take his word as face value ... come on man. A massive concentration of Indian troops (i.e. a Indian troop buildup) will just make them even more vulnerable to Chinese artillery fire due to the compactness of Indian troop concentrations in the area and a complete lack of defensible infrastructure. It is true China would rather resort to salami slicing but make no mistake, it will pretty easily expel Indians out with artillery fire if need be. Please tell me how Indian troops guarding some heights and passes will be able to survive repeated volleys of Chinese MLRS or even standard conventional artillery ... even if they built bunkers or hardened structures, they too would likely be demolished. The only thing that could possibly save the Indians is if they dug a massive tunnel or cave infrastructure network, but their infrastructure abilities are nowhere near that point.
