Regular troops of the 78th Group Army armed with full-length QBZ-191s.
Also note that solder in the fifth row back (right side of the picture) sporting a QBV/QBU-191.
All here without optics, but I wouldn't be surprised if they were only recently re equipped.
Of interest is that the QBB-95 is visible in the third row back (noted from its bipod, visible), so at least for this unit, for now the QBB-95 will remain the IAR role.
Will be interesting to see if they eventually get replaced by the QBV/QBU-191. After all, giving it a drum mag or even giving it more standard 30 round mags for the soldier carrying it will allow it to perform quite well as an IAR as well.
