The other day an interesting video was published online. To determine the time and place of shooting is quite difficult. Definitely it can be said that these are not the eastern provinces of Syria. Given the dense, by Syrian standards, vegetation, you can put forward the assumption that the action takes place in one of the three provinces - Aleppo, Idlib or Hama.
The frames show the joint work of the Russian MTR fighters and the Mi-28H pilots. The former suggest the latter on targets on the ground.
