I know that they wont "intervene"
In all armies aply our army's unoffical motto: the faster you do it, the faster it will happen. In PLA the chain of protocols and correct procedures are just too burden when the decissions, even the one that says where the battalions trucks are to be deployed for the next dayligth, needs to be ligthing fast. The commander gives the orders to his sub-commanders to conduct. No party comitee meating in that nor that someone else makes the decission.
We can keep this debate over and over and over.....But the reality is that you use western model to create a "Chinese situation" which doesn't exist in PLA, and start to critise it.
I don't konw what "protocols burden" you talk about? A commissier acts like a vice-commander in combat situation and the commander is in full control, who knows everything and in charge of everything. And "party comitee meating"? This is the first time I heard that PLA needs to do a party committee meeting in combat mode.
If you create a straw man and keep beating it, you always win. I quit this kind of debate.
