I will be honest.
When I received orders to deploy to Desert Storm, I did not want to go. My allegiance is to the US, not Kuwait. But orders are what they are so I went home and prepped my mobag. The US military performed exceptionally in Desert Storm, not for Kuwait, but for the US. Our country wanted us to do X, so we did X and then some more. Everything we did in Desert Storm, we did it in the service of our country. The Iraqi Army did horrific things to Kuwaiti civilians and we felt terrible for the Kuwaitis as we treated them, the women and girls were the worst cases, no surprise there, and no doubt some of us took out our anger to the Iraqi Army over that famous 'Highway of Death'.
The PLA is not (yet) a professional military no matter how much shiny new toys they have. How long until that 'yet' is gone? No one knows, certainly not the PDF Chinese cohort here. Whatever failures they had in the service of the UN could be strictly personal, meaning they would have failed their duties in spite of whatever the PLA trained them to do. One maybe two soldiers, I can see it possible, but the entire squad ran away? That is institutional, not merely personal. You were given orders to do X, but then something threatens you if you do X. A professional army would fight to accomplish X.
