the turks (fsa/nsa) are "the baddies," backed by nobody really, and their enemies are the assad govt backed by russia, with some involvement by the us-backed ypg/sdf in support of the russian forces.  in 2018, the turks launched an offensive against the us-backed sdf forces in syria and freed a ton of isis to create the "new syrian army," which is a recreation of the older us-backed free syrian army as a turkish puppet organization.
