Two Syrian rebel militias judged moderate in Washington have in the last few days taken delivery and begun using – mostly in the Idlib region – the first advanced US weapon to be deployed in more than three years of civil war, DEBKAfile’s military sources reveal. It is the heavy anti-tank, optically-tracked, wire-guided BGM-71 TOW, which is capable of piercing 50mm thickness of Syrian tank armor and Syrian fortifications at a range of 4 kilometers. Armed with this weapon now are Brig-Gen. Abdul-Hila al Bashir, the new commander of the rebel Free Syrian Army, which is headquartered at the Golan town of Quneitra, and Jamal Maarouf, head of the rebel Syrian Revolutionary Front fighting in the north. The appearance of this advanced missile radically alters the balance of strength on the Syrian battlefield. It also denotes a striking change in Obama administration policy, which hitherto flatly resisted every demand to provide Syrian rebel groups with the heavy arms essential for them to have any chance of standing up to Bashar Assad’s superior military strength.
