A Free Syrian Army member fires an RPG-22 on 12 January in Busr al Harir in Daraa Province
While foreign weapons have been seen in Syria, we have not encountered them on this scale. All this suggests a new, organised, and well-funded effort is under way to ensure that "moderate" fighters are capturing territory and weakening the Assad regime.
It is too early to tell whether there are enough weapons to make a long-term impact. None of them be used as an effective counter to Assad's primary threat, his fighter jets. However, if this is an experiment to see a surge in armament makes a difference, the answer is clear.
