We are really getting to see the Russian Air Force in action over Syria like it has rarely been seen.
For the Russians, they are supporting one of their principal allies, and they are showing the world that they have their precision weaponry and capabilities too.
For the US and the west, it is an opportunity to get very, very good intelligence on these aircraft in a way that they seldom have the opportunity to do. I mean, US AEW and AWACS aircraft are up in the air in the relative near vicinity, as well as other coalition aircraft.
Here are pics of the SU-24, SU-25, SU-34, Tu-22M and Tu-160s (with SU-30s escorting) in action:
