WEll keep in mind that the CPV durring that time were armed with weapons issued by the Americans to the nationalists. The supply system for the Chinese was so bad that they opted to carry American weapons captured from the GIs as they escaped south. The Chinese were armed with American, Japanese, German, and a few Soviet weapons. The Russians really didnt supply the Chinese until after the war since China was still a very new Communist Country. Later on durring Korea they were armed more with Soviet weapons, but they still lacked Armor and Air support. The Chinese simply did no use Close Air support...peroid. They did have a few bi-planes that might fly over trench lines in the later stages of the war and hand drop bombs...but most of them met their fate via a DUSTER or Quad .50
If you know some Chinese here is good photo source.

I have a couple of Chinese sources on the korean War, but they are in Chinese and I havent had it all translated. But all the evidence ive research have supported this. The problem with research on the Korean war is that as it is in America, the Chinese view it as a Forgotten War.
