SOM Cruise Missile : Turkish designed and manufactured

Yeah but if they start using cruise missiles to quasi-nuke the YPG in northern syria (even using large conventional warheads), and even discounting that they'd kill large numbers of american agents, won't that ring the alarms and radars of basically every military powers in the area ? >_>

And i would'nt put it above S400 capabilities to blast those away from Latakia, depending on the angle, early warning (firing delay) and a bit of luck.

Say could't some kurds-friendly operator with an eye on turkish missile and some vague knowledge of russian processes (you know like totally not former red army officials that happen to be totally not found in the ypg-friendly PKK by sheer coincidence ?) transfer incoming missile telemetry to the russian air defense already in place.

Then you'd have a huge scandale where the NATO turks missiled Syria while getting stopped by russia, to deal with on top of that and that would even make putin look stronger and capable of barring evil nato plans (which would be bad for NATO i guess so better tell them early ?) (i guess RT.com would have a field day).

Additionally, barring the specific deployment of advanced anti-missile Russian equipment to Rojava itself,

Well, given proper targetting data to make up for the radar coverage loss in the area early enough to compensate for the distance, hypothetically the S400 in latakia would cover the jarabulus area.

and its Western allies have entered a phase of the anti-ISIL battle in which they are quickly losing face. Especially with Russia gaining the propaganda edge.

Exactly, so i hope we avoid such scenario where i'd become a "choice" between handling a direct hit by turkish cruise missiles or giving the russians the actual means to blow them away.
