Regarding the 1, 2, 3 - II - it definitely must be indication of missiles in containers - I thought of AKM version which has different indicators above panel. AK has indicators for missile presence here in this panel.
Indicators are in different order...
9K33M2 OSA-AK (SA-8B Gecko)
9K33M3 OSA-AKM (SA-8B Gecko)
But Im interested in the 9K33M2 OSA-AK (SA-8B Gecko)!
