S-400 arrives at Russia's Syrian Airbase (vid)..via Alert 5.

Uh...I don't think this is the short range version...and I do believe its being paired with the "stealth detecting" radar.

Yeah.  As of this moment, Russia can protect its airstrikes against Turkmen forces (as if they need to do airstrikes...they're well within Grad range) without putting one fighter in the air.

The battlespace in Syria just got MUCH more complex.  Lets hope that our military forces are more professional than our political leadership and will work with Russia to deconflict this battlespace.
