Are those armor models or just skirting?
The Skirts of a tank are thin normally just some sheet metal and rubber. The goal being more to keep dust down. The side plates never looked like they were armor so much as a cover for the Bustle rack.
Can understand stationary turret and moving hull like the Japanese and German demonstrations but turret on the move with the tank? Unless the friction between the surfaces are THAT significant, I reckon no glass of water is staying put without some adhesive assistance. Sorry, I know the 99A is good and all and has a stabilisation that can rival the Type 10 and Leopard 2 in this type of demonstration (not particularly difficult by modern tank standards even a T72 could manage) but accelerating it is impossible.
