It seems like there's still improvements that can be made, but the thing is, we really don't know how representative or good that footage real is.
Could be scripted to be shown to tv (this stuff has happened before), the footage could also be old (something taken a while ago, possibly years, but finally actually shown) or only be part of training (so there could be better/more realistic training not shown).
You are absolutely right, the training in the this pictures just shows a indication of Urban warfare, but it’s nothing compared to Chinas abilities, there millions of improvements how to betterment this training, when we just start to pick every pinch in this pictures. First of all I don’t see any lasers on the bodies which is essential of modern training, but we don’t know anything about the purpose of this pictures, so crispy criticism could be hold back, last but not least, the Chinese BMP should attests have a urban warfare kit, such as caged added armour.
