Summary:
"With its fielding of the PCH191 multiple rocket launcher (MRL) and its variety of long-range precision munitions, the PLA Army (PLAA) has become arguably the most important contributor of campaign and tactical firepower during a joint island landing campaign against Taiwan. No longer simply the primary source of amphibious and air assault forces, the PLAA is now capable of using its multiple battalions of PCH191 MRLs to support maritime dominance, the joint firepower strike, and ground forces landing on Taiwan’s shores and in depth. The Chinese ordnance industry has developed multiple low-cost rockets, an anti-ship cruise missile, and a tactical missile to be used with the PCH191, as well as its export variant, the AR3, including munitions that can quickly and precisely strike targets in the Taiwan Strait, across the island, and beyond. Recent demonstrations of the PCH191 during PLA training events and Eastern Theater Command response actions to politically charged visits, in addition to the fielding of new reconnaissance assets capable of providing targeting and battle damage assessments to the MRL, make it clear the Army intends to use the system to achieve effects in a future Taiwan crisis that formerly would have been the responsibility of other PLA services."
So what I get is basically the PLA is gonna use it's modular MRL assets to do precision strikes and even anti-shipping roles on top of area suppression/saturation fire role. Meaning that grunts landing in Taiwan, rather than relying to ship/air based precision strikes, have the option to call their own army units instead and provide it from MRL units from across the strait.
