China didn't copy the german army
they will built there own version. That means, the german
advisers said only the approximate structure, the Chinese fixed the actual structure. Also, the
naming of the Chinese units is not always the "German model".
A chinese brigade is not as big as a german one.
..the same with all other units...
Keep patience !!! Wait till the whole structure is shown in the encyclopedia. Perhaps the one or the other note then belong to the past.
