What is really interesting in these S-300PMU1 (SA-20A) shots, is the additional officer.

Compared to the S-300PMU (SA-10B) where 5+1 officer works in the F-2 cabin.
From let to right: firing officer, target acquisition officer, and 3 manual trackers (range, and two angles).
Behind them sits/stands the commander.


Here you have 6 officer workplace: firing officer, azimuth officer, target acquisition officer, and 3 manual trackers (range, and two angles). Either the commander stands behind them, or he takes the azimuth officer position...
