To clear up some misconceptions (hopefully not leading to further debate)
Marat is right about M-113's and ACV-15's being supplied to TFSA. HTS did get their hands on some, but this was provided to them via TFSA. They are distinct because they are unarmed, intended to be used purely as armored transports. Hence the video sometime ago of an unarmed ACV-15 engaging an SAA tank. And no, it was not an SVBIED.
There are currently 3 fronts to this whole Idlib thing. The EW aspect, which is purely Turkey and Russia. The air aspect which is Turkey-Syria/Russia and the ground aspect which is heavily Turkey-Syria/Iran.
The successful counter strikes by SAA was with heavy Hezbollah participation. One could say this has caused some issues between the Russians and the Iranians. Russia has been "uncomfortable" with heavy Iranian ground presence for sometime, and Iran is trying to help gain territory on the ground as a way to assure the SAA that they are more effective on the ground, than Russia is in the air.
TSK has lobbied heavily to deploy the Hisar-A and Hisar-O to the border. Up until now only HAWK's were deployed. The Hisar-A being the short range AA, and Hisar-O being the medium range AA. Technically the Hisar-O was not supposed to be ready until early next year but it seems this Idlib deployment will also be seen as a testing ground to improve the system. While they are no Patriot's, the military has to be realistic of a very possible "no" answer from the US/NATO. This in turn has defined TSK strategy in Syria. Make do with the local low/medium AA systems, do not cross the borders with the F-16's (the F-16's and Phantoms have all performed their airstrikes from the Turkish side) and apply all EW capabilities in the area to support the drones while they try to knock out any threats that would create the need for a long range AA system like Patriot or S-400 to begin with. If the Patriots are not sent I do not think there will be too much damage. If its one thing we shouldn't forget, the only reason you see all these drone strikes by Turkey is because the US refused to sell their own in 2008, forcing Turkey to produce its own. Delaying the sale/delivery of equipment you produce will only speed up the process of producing the local equivalent.
There are no plans to pull any article 5 from this, somebody said earlier that Trump told Erdo so. Not sure if he actually told Erdo this, but it's not necessary because everyone and their mother knows this is not article 5 worthy. There is still more dialogue with the Russian side about Idlib than there is with the US.
Also the Frenchy who knows who he is. You do not see ISIS patch, rather the seal of Muhammed. I know the difference is hard for you to grasp but there are more French citizens in ISIS than Turkish ones, so I would expect you to know better.
