Accidentally posted this one in the Type 100 tank thread. I was right about the rear ramp/corridor layout and also having a seat which makes it very likely to fit about 7 dismounts. Though in the very short flash we got I could only count 3 dismounts getting in but others could have entered off camera.
In the English stream it was called "Type 100 Fighting Vehicle", it may get a "ZBD" designation or not. We´ll have to wait for further confirmation but to me its essentially an IFV.
