I am a little surprised by this. They surely cannot let Russia run roughshod and I know they gave warnings, but they still could protested diplomatically and warned that ‘next time’ we will shoot.
Until now I would have thought Turkey could play both sides against the middle, with NATO membership secure they could move very aggressively towards being a Russian ally in all but name only and maybe get the best of both worlds. There is an axis that runs Moscow - Ankhara - Damascus - Tehran, should be beneficial to Turkey. Maybe this was the army acting without explicit political support? But now I am reminded of how angry they were when Israel boarded their Gaza blockade running ships. Turkey isn’t in a spot to complain about aggressive defense of territory anymore.
