It’s pretty much a T-80BVM sidegrade, if implemented with chinese ammunition. Better reverse gear + better armor thanks to welded turret and effective ERA (unless devs use some “reliable” sources to nerf it) but worse acceleration (1200 hp engine on Oplot vs 1250 hp engine on BVM) and rather weaker rounds (it is known Thais use BTA4 / 125-II for their VT-4s, and their autoloaders should both accomodate the round)
