I know that they wont "intervene"
The point comes from the orgins of the authority that is the first link in the chain that creates the dicipline and therefore the unit's figthing capability.
Also fast decissions and flexibility in combat enverioment is needed in other things as well, not just in the fighting. Support, logistics, supply, evacuation and housing are as nesserical as they are in garrison life, even more nesserical. In western armies there is a quarter-master that manages these things, but he doesent make decission over them.
The concern that I have rises from the idea that in combat enverioment, the leader needs to be aware and responsible of all matters, not just from the fact how he deploys his mens into bill-boxes or how he plans to overtake the next enemy controlled town.
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.
Situation awareness is one of the key issues to survive in the battle field, It is severly compromised if you need to be in the mercy of someone else in the crucial non-combat element. You dont need nothing more than wrongly done plug-in by the radio operator and the whole unit migth face chaos as the two commanders migth not be able to communicate fast enough...
And thats is where i drawn my main thesis. In the field, the chain of decission making counts lot more than simple weapons or even how brave the soldiers are. The system that PLA has brings unnessery and heavy burden upon that chain and in modern warfare, the elements that affects to this chain are even more accute than ever
