Thank you both, SOC and EugeneF, for your interesting informations.
Performance of Gazelle seems to be in the same range as Sprint.
And apart from mobile Radar support ,Gorgon - as piggyback on SS-20 MAZ - seems to be just a few steps short of a "mobile abm" Best Regards
P.S.: I still think that the Galosh Picture shows a sort of scaled down mock-up; this damned thing is too short and never in a range of 20m.
