War in ukraine

The unified mixed anti-aircraft missile brigade of the Russian Aerospace Forces, which forms a network-centric air defense and missile defense system in the Mariupol operational direction, includes both 6-channel self-propelled firing units 9A317M of the Buk-M3 complexes and 1-channel self-propelled firing units 9A310M1 of the Buk-M1 complexes, as well as the short-range air defense systems Tor-M2 and Tor-M2U.

The work of the latter's crew is captured in the video above.
A positive is that the Tor-M2U PESA radar also has 4 channels like the more modern version.

Unlike the modernized Tor-M2, the U-class system has ammunition based on the early 9M331/D interceptors.

These anti-aircraft missiles are distinguished by their aerodynamic "duck" design (the 9М338К Р3В-МД has a load-bearing body with sections of tail aerodynamic rudders and destabilizers), available overloads of up to 23G (up to 40G for the 9M338K), a maximum speed of up to 1000m/s, a simplified radar fuse, a range of 12 km (up to 16 km for the 9M338K) and an altitude range of intercepted targets from 10 to 10.000 m.

But despite these shortcomings, the 9M331D missiles are capable of intercepting JDAM-ER gliding guided missiles with a probability of 0.7–0.8 at a distance of up to 8 km, 227mm GMLRS guided missiles at a distance of 5km, and GLSDB gliding guided missiles at a distance of 4–3 km.
