The Middle East is rich with all sorts of Russian-made anti-aircraft systems. Most of them were delivered to the Arab countries opposing Israel and, in the time of the Soviet Union, to other clients on a political pretext.
The flow of modern anti-aircraft systems to the area continues, although in lesser quantities. Russia is often viewed as a preferable supplier for that sort of weaponry due to the long story of success of its anti-aircraft systems. It has been estimated that anti-aircraft missiles made in the Soviet Union and now Russia have seen more launches than such weapons made in all other countries combined.
