(Sighs) I love google. An Il-2 stationed in Kimpo Circa 1950. Not sure if it is DPRKAF or if it is PLAAF.
I have heard that Russia loaned some of it's pilots to the PLA and DPRK to fly in MiG-15's. According to a documentary, the USAF pilots could tell the diffrence in flying skill. Of course, this is all subject to conjecture.
As far as what the Chinese used, they used WW2 Vintage rifles, SMG's and LMG's with some of the newer Russian equipment and vehicles. As well as the weapons they themselves used in WW2.
The Chinese 'Victory' is a bit disputed. Technicaly speaking, the war has not even ended yet, so no-one won. Which is why there is still a North and South Korea instead of a Chinese Peninsula or Communist Korea. However, the Chinese definately hit our nerve when it came to the conflict. We were woefuly unprepared for this kind of combat.
By the way, I happen to enjoy M.A.S.H. One of my faveorite episodes was Rainbow Bridge, when Hawkeye, B.J and Burns had to help the Chinese soliders? I just love that bit where Burns pulls out the little peashooter and the PLA officer goes "What the hell is that?!" then laughs as he holds the little gun....ah...good times.
