Russian Air Defense System - S-400 Triumph (NATO: SA-21 Growler). Deployment and live fire exercises
Russian army testing the S-400 Triumph anti-aircraft weapon system via rapid deployment and live fire exercises.
Russian forces have deployed S-400 in Syria, and while this defense system is believed to be one of the best in the world, it so far has not been able to prevent Israeli air strikes on Syrian territory. Likewise, no S-400 have yet been destroyed by an airstrike.
