I agreed but at same time US combat experience doesn't count since it's not even impressive. It's usually the might of NATO vs a small country.It's true. But of course the units doing parades are probably not the same as combat units.
Real combat is much different than stimulated combat. But again, I doubt infantry combat is relevant to a US China conflict. The experience US has is very important and a big advantage but it doesn't mean Chinese units can't fight well either.
I think China needs to focus on making training more realistic. The recent addition of the colored smoke helmets to signal kills is a step in the wrong direction. They don't seem to use systems like MILES.
Also people from top of the chain to the bottom need to be tested in leadership and improvisation. Rote training is only 25% of a skill set. The US does this training really well.
I think China realizes these issues but is probably more focused on training naval and air units. I'm not familiar with training in that realm but it's not like the US has had experience in these fields either other than bombing hadjis.
