Chinese PLA has consistently been facing the brunt of IA - in terms of these H2H combat that has now become the norm between the two armies. There is a reason why the Chinese have not resorted to use of firepower & I bet it's not because they don't want to. I am pretty sure they want to keep their loss (in terms of KIA) less so as to prevent an internal political disaster which goes out of the window once the bullet starts flying. The only thing that I fail to understand is the tactics - these rush and grab type of ops have been a failure for quite some time now, and yet, they come back and try again. What is the threshold here, when do we open our MGs and wreak havoc to an incoming Chinese group, I guess never. India is keen on giving the Chinese a face saver after each and every failed attempt - this is something that will come back to bite in long term.
