In its coverage of the event, Time magazine suggests that the
Israeli raid might be connected to the acquisition of Russian-made Pantsyr-1 air defense systems by Syria and Iran. Damascus took initial deliveries of the system in August, and Iranian crews are likely training on the Pantsyr as well. But the destruction of an air defense training site wouldn't account for that "big hole" in the desert. The attack was apparently concentrated in an area that's not far from known Syrian surface-to-surface missile facilities. Given the scope of the damage inflicted--and the apparent size of the Israeli strike force--we're guessing that the attack was aimed at more than air defense equipment.
In any case, it looks like Hizballah's order-of-battle will be missing a few items, at least temporarily. The raid was also a wake-up call for Damascus and Tehran, reminding them that the IDF can reach remote targets with air and ground forces.
