Is the idea of a Chinese saturation attack using rockets in the near, medium and far range within a 200 km combat radius valid?

It is feasible for rocket artillery to conduct saturation attacks at 200 kilometers, such as China's WS-2 with a range of 360 kilometers. Firepower can cover enemy airfields at long range. Command posts, radar stations. Enemy artillery positions, etc. But long-range rockets and missiles target point targets.

High-speed advance of ground troops depends on air control. Use combat aircraft to kill enemy infantry at point blank range. Destroy enemy anti-armor, anti-low-altitude defense capabilities. Only to ensure the high-speed advancement of ground troops.
