There were tactical advantages to the terrain in WW2 - similar ones exist here but what I am referring to is the seemingly pointless existence of Helos and artillery to what has become a very cautious conflict.
A mix of riot gear and good old mano-a-mano is what leads to territorial gains in this conflict.
The chinese may be helped if they pull out their riot gear and associated “soft” weapons. So stay within the threshold of non-deadly force but essentially beat their opponents into submission.
The high altitude nature does not permit long drawn out brawls so it will be the ones with the hardest punch or the ability to outlast and tire their opponents quickly that will win the conflict.
