Well actually there is a hidden retexture of this uniform, place a CSAT soldier or someone who is wearing the CSAT uniform in the editor, and type this into their init box: this setObjectTextureGlobal [0, "\a3\characters_f\OPFOR\Data\clothing_rus_co.paa"]

That's the point. To remove that, and create a new one, that looks far better. A Re-texture would be horrific, and would also cause alot of issues. Being that China is a Super Power on it's own, would not need to share uniforms that the Iranian counter part of CSAT uses, as China manufactures it's very own uniforms. In any case, other forces should be wearing Chinese made uniforms, as China, i believe, does supply certain gear and weapons to certain countries. I'm not too sure about the South Pacific, but this is mainly in regard to the Chinese counterpart to CSAT. Something new, and fresh is needed, not a re-texture.
