Air Brigade > Dadui > Zhongdui > Fendui
Also noted that a Dadui leader in this new Brigade structure has a "battalion grade" while the deputy commander of the air brigade has a "regiment grade".

Короче, похоже, что китайцы решили перейти на структуру "авиабаз", от которых у нас отказались, назвав их бригадами. Причем у худшем варианте - баз 2 класса, причем смешав в составе, скажем, дальников и истребителей. ДБ!
