[Constantine XI Palaeologus]

Even if they did have the Pantsir, it's a short range system. The Syrian air defense system is hopelessly outdated, and as such is susceptible to programs like Suter.

Besides, the Pantsirs--which were delivered in August 2007 (wikipedia)--the only halfway decent SAMs they have are SA-6s, which the Israelis had wised up to by 1982.

There are several countries selling digital upgrades to the older Soviet SAMs. They make the older systems much more competitive at a very low price when compared to the new ones. The SA-6 today is not the same one of the Yom Kippur war. Same goes for other older systems
