I suggest you visit a public link such as CCTV-7 ( 军 事 报 道 ).
All PLA commanders who buy into Chairman XI concept of ((
Able to Battle and Win Wars + Taking the Battle to the Enemy Territory ) by applying the Core principle of ( Innovation on Everything )) have been urgently and diligently designing the PLA exercises to be as close as possible to the real battle environment.
Let's say for now ... ... taking the battle across the sea to Japanese cities.
This means
PLAAF pilots must use every terrain features to hide their equipment from being scanned by enemy radar.
If PLAAF do not practise Night Time Confrontational exercises now, then when the East and South China Sea War breakout, ... .... how can you fight on the Enemy Territory and win the battle ??
It is better to anticipate and spot all the problems now ( for example * Night Time Low Level Flying * Confrontational exercises ~ and how to avoid collision with civilians Quad Copters ), and finding the Innovative and Scientific solutions asap. ** Discovering the problems on the battlefield is a recipe for disaster and National humiliations.
