Well, Pla 3.1 is a mod that was made by VME team. Then there's another person called Nocture wants to make a total convertion mod that replaces US and USSR with PLA and JSDF, and he is granted the permission to use VME models. However, the models and textures that VME made are a little bit crude and out of date, so he made a lot of new models and textures. The totle convertion mod which is called Virtual War Asia Mod is still in progress but he has published most of his newly made weapons and units, and approves VME to use them in their own mod. So 3.2 is a mod that combines 3.1 and Nocture made new models.(PLA combat system 1.0 is more or less the same but a little bit different).
If you are interested in this mod, I suggest you pay more atttion to VW Asia mod. It will has more detailed units and weapons, and since it's a total conversion mod, it will allows you to play PLA as US or Russia as you like. So you don't need a 3rd party made campaign, just play the original game with China and Japan. Nocture is working on his last machine gun model, and will release the full version not later than June.
