Video that was originally recorded in 2013 near Otaybah, Syria, shows members of a Jaysh al-Islam ATGM team destroying a piece of armor owned by the Syrian Arab Army.

At this point in the conflict, ATGM strikes in Syria were fairly rare. The FSA, and all of the splinter factions that make it up, did not have wide access to anti-tank guided missile systems. That is also why we're seeing the system used to target an actual piece of armor, as later in the war ATGM systems were turned into bulky sniper rifles that the FSA would use to target individuals and groups of SAA conscripts standing in the open.
