The conclusion from this is pretty much one of two things...
1) it's all smoke and mirrors,
2) the Russian air force is nowhere near as competent as we assumed.
This report you link suggests it was a convoy of 100 trucks, nice to finally get a number of vehicles instead of random numbers talking about men. Such a convoy should hardly be feared by a global superpower on their own territory.
To say the Russian air force is incapable of taking out this convoy is to say they are a shit air force.
