Type 96B is not in production yet ? I find that quite surprising honestly since I remember seeing many pictures of 96B tanks in training exercises (not the tank biathlon). Where did you get this information from? It's really shocking to not be in mass production considering we saw the 96B over 4 years ago ...Chinese language Wikipedia's figures are as below:-
2,500+ type 96 and type 96A
500+ type 99 and 500+ 99A
are in PLA service.
Also, pls note that type 96B is not yet in mass production. The few units in existence are mainly for evaluation/demo test purposes.
Participation in past and future Russian army games was and will be a good testing ground to expose its strength and weakness. I suspect there will be changes to current type 96B. Probably they might use some technology from type 15 light tank before official induction into PLA.
