On 18 September 2020, another Turkish military convoy entered the Syrian province of Idlib
This shows that Turkey is gathering in Idlib a very serious force, which is not just more than enough for defense, but more than enough at times. So the group is gathering there on the offensive.
In addition to transferring military equipment and building military bases, Turkey also uses Idlib as a training ground for military exercises.
It should be noted that joint patrols with the Russian side have not been conducted for quite some time.
