The footage appeared on Youtube on October 29 shows a member of the so-called “46th Infantry Division” of the Free Syrian Army’s Southern Front with a Man Portable Air Defense System (MAPNAD) in Abtaa in the Syrian province of Daraa. The MANPAD shown in the video looks like a Soviet-made 9K32 Strela-2 missile. Nonetheless, the shown missile tube has a lack of thermal battery (without the battery it can hardly be used).
No more information is aviable now.
