As reported by Censor.NET citing The Wall Street Journal, the Pentagon officials said Islamic State seized equipment including an SA-3 surface-to-air missile system, which uses Russian-designed missiles designed to destroy aircraft flying at altitudes up to approximately 16,000 feet (approx. 4.8 km). Pentagon officials said American aircraft typically have systems that can deflect such munitions and said the militants don't know how to operate the complex equipment.
The Pentagon said the equipment was seized from the Tiyas military airfield by Islamic State forces as they advanced on Palmyra between Dec. 11 and Dec. 13. Islamic State had captured scores of Western armored vehicles, artillery pieces and other weapons when the group stormed into Mosul, Iraq, in 2014.
On Thursday, U.S.-led coalition aircraft destroyed a total of 14 tanks, artillery systems and an air defense artillery battery, according to a senior military official.
