All of the few available photos of that "Terminator" probably show the same one vehicle... They certainly appear to do so. From this, I would suggest that there may be all of one such IFV in Syria - so far.

Has it actually seen any combat in Syria? Until someone surfaces some pretty clear and reasonably well-documented photos showing that, it would seem more likely that the answer is either "no, it hasn't participated in any combat action" or "yes, but only in a very confined, controlled and limited role".

The Terminator is expensive and rare, and is pretty much state-of-Russian-art and not much finite detail is actually known about it in the West, and I would wager that the Russians are pretty careful to keep it away from any serious risk of getting destroyed or, maybe more problematical for them, captured and turned over to any of many hungry Western countries for evaluation and testing. While designed to be a heavy fire-support vehicle to support troops in urban combat settings, I am pretty sure that the Russians are less than fully-confident about how well it might fare in the urban "jungles" of Syria - their previous experiences with heavy armored vehicles in tight urban situations haven't been very successful - and the opponents it could face in Syria are better equipped and maybe better-skilled then the Chechens, for example, were...

If one wishes to model this individual, there are kits available (Trumpeter and Zvezda both, I think, produce a "hybrid" kit which would best represent this vehicle). As indicated for the posted pics, the original "urban splinter" camo scheme may have been painted over. The available photos would be one's best guide for painting the presumed "Syrian Terminator".

IF it, or any brother Terminators, actually do see much field action in Syria, we will eventually see some "action" photos - it's the way of the modern world: cameras are EVERYWHERE!
