If you look closely at earlier pics in the thread, the tank has been seen more often than not with a commander's sight resembling that on the Type-99 series. PLA is still cheap and all, but I think this is just a case of them not bothering to have them installed for the parade tanks for whatever reason. The parade tanks also happen to be missing the 35mm AGL and some applique armor.Commander's optics seem to be fixed like in Type 96. I guess Chinese army doctrine do not require it since the whole tank strategy is nearly always send them in waves and angle of focus for each individual tank is so small. Guess they consider the savings to be worth it. The high end tank type 99 series have always had independent sight though but gunner's sight is still fixed to the gun.
