Yeah, that one looks like some kind of demo or practice, not a real combat.
There are currently a series of Syrian-Russian war games taking place.
The Syrian mil has to know how to interact with the Russian marines, naval forces (includes several missile ships and one Typoon nuke sub Donskoy /TK 208/ w/nukes) while using/interacting with Russian equipment: including MiG-31s, Kornet antitank missiles, BA82A fighting vehicles, KamAZ-6560 trucks.
This may have little to do with fighting ISIS, or even keeping Assad in power, but rather “protecting” Israel’s Leviathan oil field - one of the largest in the world, and building a pipeline to Turkey.
Russia wants the gas/oil.
