Once again not talking about the average infantry force here, but rather SOF made for conducting specific specialised missions. The point I was making is that improving SOF equipment (Not all infantry) is not much more costly than compared to a small european military. As learned from the Sino-Vietnamese war, you do still need SOF for infiltration missions, recon, rear-line sabotage and etc. I believe focusing heavily on aspects of the ground force such as IFVs, Artillery, and heavy firepower does make a lot of sense, but not when you forgo special forces whose role can't just be replaced by pumping the budget elsewhere. This is like going all out on drones, and leaving your MBT force to rot because drones have much higher yield/cost ratio.On the contrary, for a military the size of the PLA, including the size of the PLAGF and other services with infantry (PLAMC, PLAAF, even PLARF), equipping their infantry in a modern way similar to leading infantry warfare military forces, would actually cost quite a bit.
Small scale European military forces can equip their infantry well exactly because the ability of them to wage large scale conventional war is more limited, and also because they have to structure their forces to focus on certain aspects of quality rather than balancing it against quantity.
Personally I feel like we are getting to a stage of PLA modernization where they can progressively open the wallet a bit more for their infantry (or perhaps even limited units such as SOF brigades -- modernizing all PLA SOF units to a better equipped standard could be somewhat doable without breaking the bank), however I also strongly understand why they're reluctant to do so, because the money can very legitimately be better spent elsewhere for higher yields, considering the scale and sophistication of the opposing force that they're facing, and how relatively unimportant infantry is for that mission/threat.
However I also take some degree of perverse enjoyment in seeing people accept the reality that well equipped infantry is relatively unimportant in modern large scale conventional warfare, relative to things like networked artillery, networked mechanization, availability of EW, and cross domain fires. It is a shame that video games have glorified "muh operators" and super commandos, rather glorifying the lowly artilleryman and the crew in the fires direction center tinkering with their maps and compasses.
One thing that should definitely be on the PLA's mind for all infantry thought, is the widespread usage of fpv drones and etc, at least much more than what is currently seen.
