Geez. Who knew terrorists had combat engineers?

After the public protests on the highway last week, militias have taken a more permanent action against joint Turkey-Russia patrols in Idlib in Syria. https://t.co/ieJN5bFr7B

Wow.  This is next level trolling on the part of the terrorists.  It's also a bit telling about the forces in the region.

No one had visibility on them doing this?

If they did have visibility why wasn't a JDAM strike (or equivalent) put in motion to stop it?

Terrorist combat engineers.  Shaping the battlefield for terror into the 2020's.
