Generally speaking, in Korea it was relatively easy to distinguish between Russian, Chinese and North Korean pilots :
- For many, the Russians were World War II veterans, some with several victories under their belts, and therefore very tough and dangerous. Many aces.
- The Chinese were much less experienced, and were converted to MiG-15s in a hurry. Some already had experience on the MiG-9, others on the propeller-driven Lavochkin. In any case, at least in the early days, they were not very dangerous and were regarded by the Americans as "cannon fodder". Some became aces.
- The Koreans had even less experience and were few in number, but some became aces also.
