Wheeled, medium brigades are good for a medium scale war against a conventional enemy, like India or Taiwan. These ones are the potential enemies faced by the PLA. The US has need for heavily armed IFV because they are fighting anti-insurgent, policing wars. Unless China's main enemy are guerilla insurgents, the medium brigades are very well rounded method of force projection.It's bonkers though. Even the US realized this and then went with the GCV program. Only to backpedal on it. It is simply a cost cutting exercise. If the Syrian conflict is any indication proxy wars are going to see a lot more proliferation of ATGMs. Lightly armored vehicles have no chance. The idea the conflicts are going to be police actions against firearms like it was in Iraq is nonsense IMHO.
