Talked to an old man that used to work for the CCP around the time of the cultural revolution, after Mao. The three most corrupt agencies then were 1) anti-corruption department, 2) human resources equivalent, and 3) military. (1) to prevent getting caught, (2) to expand the corruption to more lucrative areas, and (3) to ensure CCP survival.

If they are following the same model, then unfortunately corruption will be quite prevalent in the higher echelons of military, as seen by Vindman and the like. Those like Flynn are exceptions.
