Recommendations for PLA force development/training and procurement (note, I do not include procurement and development of new technological systems like swarming drones, stealth bombers, UGVs etc, or other systems that have not been shown to be mature either in the PLA or in international service)
-Procure PGMs and integrate with fighters and bombers at a relatively large scale -- the PLA are at a state where this can be afforded and it is a significant force multiplier and a necessity for a successful CAS and interdiction capability. Export showcases does not mean you have a large magazine size and integration among fighter types with training. Similarly, the 500kg LGBs that the PLA has in service (with JH-7/As and J-10A/B/Cs) are simply too large and does not allow for sufficient magazine-size-per-sortie to be effective. MALE UCAVs carrying 6-8 KD-10 sized ATGMs and 2-4 50kg PGMs is not a replacement for fast jets carrying a half dozen 250kg PGMs and a targeting pod.
-Buy aerial sensors (targeting pods, SAR pods, drones, JSTARS). This is obvious. All weather ISR capability in a distributed and persistent manner is vital to break opfor counter attacks, to conduct reattacks, and also to strike targets of opportunity, all in a dynamic ground environment.
-TACPs and JTACs are important and should seek to be trained and proliferated at as low of echelons with the army and marines as possible. The role of TACPs/JTACs in supporting CAS cannot be understated, and the role of CAS for enabling inserted forces cannot be understated either.
-SEAD/DEAD is important -- more EW/ECM, more ARMs. Goes without saying.
-Train for missions at scale and with the full spectrum of forces, separately if needed, ideally, in an integrated way. Complex air and naval environments in particular, and deconflicting of said forces.
-A large quantity of first/second echelon forces are vital to ensuring continuity of further operations. It will be important to procure more amphibious vessels and landing craft that can allow for larger first/second wave launches, as well as for facilities that can allow for rapid reinforcement (pontoons, mulberry harbours, with the assumption that it will be difficult to take ports in the first instance). Increasing first/second wave size and increasing the ability to rapidly reinforce them is vital. Yes, the PLA has these ships and systems, but they require more of them.
-Continue developing longer range air and blue water naval forces able to deter/check foreign snooping around area of operations, and to deter foreign air breathing ISR systems.
-Procure and build large magazine sizes of all weapon types, but especially missiles (from BVRAAMs, to SRBMs, to LACMs and ALCMs, to MRLS).
-The vulnerability of AFVs to ATGMs does not have a cheap solution. APS can mitigate ATGMs but is expensive and will be difficult to be widely proliferated. Using combined arms tactics and having sufficient AFVs to absorb losses and continue despite attritional losses, is important against ATGMs.
-Ensure that staging areas (both on the Chinese mainland, and amphibious assault ships that are deploying AAVs and landing craft) are well defended, even if one believes that opfor strike systems/anti ship systems have been adequately degraded.
-Helicopters are very vulnerable to conventional military forces due to proliferation of MANPADs. Their use must be done carefully, and likely best done in a combined arms fashion in support of ground mechanized forces rather than large scale helicopter only operations (like large scale vertical envelopments).
