The PLA has short arms and short legs - meaning that it can't get to where it's going and once it gets there, it doesn't have the logistical tail to fight.
The strength of the US Army has nothing to do with our weapons.
I served with the US Army in Egypt about 10 years ago at a remote checkpoint in the middle of the Sinai desert. I watched as every day, Egyptian conscripts were given a bag of rice and vegetables as their food for the day. Their only water was from a 55 gallon oil drum which was used for cooking and bathing and the only time they got meat was when they were rotated back to their main base.
Meanwhile, I'm on a FOB with satellite TV, air conditioning and more turkey sandwiches that I could possibly eat. That's when it struck me that the strength of the US Army does not come from our weapons - it comes from our ability to move more turkey sandwiches across the globe than the good guys can even move in their own country.
An Army marches on its stomach. The problem with a million man army is that you have to feed it and once we cut that off, the Chinese have a million starving, trained men with guns.
