Why The Interrogation Of This ...

 ... 404 POW is important in operational sense. 

It is obviously in Russian, but if anyone wants to listen to the whole thing you can follow this link to Russian MoD TG channel. But why it is interesting. It is interesting due to this and many other 404 POWs testimonies of the dominance of Russian artillery on the battlefield. This is for those who still continue to masturbate to UAVs not understanding that Fire and Strike impact on the battlefield is called "complex" because of its heterogeneous nature, meaning the use of a variety of means and artillery (both "barrel" and rocket, aka MLRS) remains a decisive factor on the battlefield providing proper fire productivity. 

Here is one of many videos of Russians tankers (this one is T-80BM) explaining how they work from both ZOP (Enclosed Firing Positions) and directly. 

Here the guys explain how they finished off one of the Leopards which was "de-tracked" by Russian infantry using Kornet and then T-80BM crew destroyed it through UAV's fire correction at the distance of 9.5 kilometers. Everything works as a system, and this is just the part, in this particular case, of ROK--Recon Fire Complex. To those who still don't get it--a reminder from Colonel Jacques Baud. 

And then there is a lot to be said about Joint Force, a REAL one.
