ISIS Weapons Video: Missile System From Russian Base In Syria Adds To Islamic State's Arsenal

The Islamic State group has inherited multiple new additions to its growing arsenal, according to a new report. The terror group recently recaptured the ancient Syrian city of Palmyra, where it found scores of powerful weapons at an abandoned Russian military base, the Washington Post reported Tuesday.

Described as a "trove," the weaponry includes a surface-to-air missile system mounted on a truck that defense-minded folks know as the Pantsir S-1, which is made in Russia. Among the other weapons found were guns, ammunition and armor.

While there were no immediate reports of ISIS having used the powerful missile system, the terror group did claim responsibility for launching an attack Monday on the T4 Military Airport in Homs, which is about two hours west of Palmyra. Some of the weapons ISIS used include mortar batteries and machine guns, ARA News reported. It was not immediately clear whether they were part of the massive arsenal found in Palmyra.

The Islamic State has been under heavy fire in both Syria and Iraq, where the terror group has reportedly lost 50,000 of its fighters. However, reports of the group's impending demise may have been overblown as the U.S. announced Saturday plans to send up to 200 more troops to Syria to aid the rebel factions fighting ISIS on the ground.

ISIS made a name for itself in part by using primitive methods for killing, including beheading its captors. However, the group eventually came to acquire weapons of mass destruction, including mustard gas against Syrian troops.

Other weapons ISIS has used on its various battlefields include tanks, chemical weaponry and robotics.

ISIS destroyed the ancient city of Palmyra by bulldozing and razing historic structures there that archaeologists have said cannot be rebuilt. A mass grave was eventually found there in April, uncovering the remains of victims who has been tortured and beheaded by ISIS militants.

The terror group regained full control of Palmyra on Sunday after Russian-backed Syrian soldiers left the city.
