(President Putin signed an order to cancel the SA-10 embargo against Iran)...
I do not believe that it is about the medium range SA-10, rather it will be the long range SA-20. Question on the number of systems, exact type (PMU1 or PMU2), and real delivery date (after long promises). At least few elderly S-200 site can be relieved.
