I wonder if this kit uses parts of the mouldings of their previous kits, or it is all new.
I've built their ZTZ-99B (unofficial designation) and it is a fairly decent kit, very cheap, but it is possible to make much better kits.
The real challenge of this kit is the digital painting.
Older versions have the usual 3 shades camouflage as an alternative, but I don't think that it's the case of the ZTZ-99 A2 (another unofficial designation, but it's the most widely known).
I think to have seen photos of an all-green one, anyhow.
