These Americans have quite a nasty attitude. First of all, PLAAF pilots are NOT trained with English as well as USAF tactics, as a standard. These guys are not the norm in the PLAAF. I believe they are the same as the PLAGF OPFOR (专业蓝军). The designated OPFOR units in the PLAGF are known to have NATO organization structure, its officers speaks English, and even with western style military rations and meals.
This ex-pilot misses no chance to imply that the entire PLAAF "stole" their authentic American tactics. While in reality, a good OPFOR units are supposed to mimic your enemy or potential opponent. Amateur American propaganda.
