I think China is looking for a short, sharp ground clash — then they will offer to withdraw to some boundary satisfactory to them (Thinking they want to control the entirety of the plateau, giving them a commanding positional advantage should hostilities resume.)
India’s trump card is it’s excellent Air Force. I don’t think China matches them pilot-for-pilot — and it’s not close.
So my thinking is that PLA does what they have traditionally done well.
Sneak-in a large, well-camouflaged force that is strong enough to win the first battle without relying on the supplies that the IAF will undoubtedly interrupt. Before the IAF can shift to close air support (from interdiction missions) the fight will be over.
That’s how I read it. I’m pulling for India. They’ve got some darned good infantry, but I think the initial conditions for the battle are stacked against them.
Let's hope that U.S. SIGINT assets catch them and pass the info to Indians.
