Footage recorded during Operation Olive Branch in 2018 shows the clear progression of FSA fighters when they are backed by the Turkish Armed Forces, but conveniently leaves out any atrocities.
Operation Olive Branch was a cross-border operation where the Turkish Armed Forces took members of the Syrian National Army into the Afrin region to clear out YPG forces that had taken control of the region. One interesting thing to note about this footage is how professional the SNA fighters are when compared to their FSA counter-parts in other parts of Syria. There is no yelling. They are aiming down the sights of their weapon systems. And, in general, they appear to moving as a cohesive unit.
This footage, which I suspect has been heavily screened by the Turkish Military, fails to show any of the things that were reported throughout Operation Olive Branch in 2018. Somewhere between 395 and 510 civilians were killed during the combat that happened in this operation. Most of those civilian casualties were the direct result of constant and indiscriminate shelling from Turkish forces. Another large portion of those casualties occurred when Gendarmerie General Command decided to open fire on refugees trying to flee the fighting into Turkey as refugees. On top of all of this, there are reports of the Turkish Military using chemical weapons in the area to displace YPG fighters.
The Syrian Observatory for Human Rights estimates that a total of 300,000 Kurdish people were displaced in the aftermath of this conflict. 800 social media users and nearly 100 politicians and journalists were arrested for criticizing this operation as well. Reporters Without Borders was barred from covering the conflict in the region, and it was noted that the only media coverage allowed was state owned Turkish Media.
So, while this footage does indeed show members of the Turkish Military working hand-in-hand with professional appearing Free Syrian Army fighters, it does not properly paint the pictures. The full picture may never be properly painted, as the only people allowed to record were those being paid by the Turkish Government.
