It could also mean 400 new operators are manning the cameras from space and covering Syrian border areas and tagging the incoming and tracking their movements in Syria and if a 'cluster appears' it gets special attention via regular Syrian Forces. For instance if the food and trucks are in Turkey and the weapons coming in through Iraq then the vehicles do enter with 'humanitarian aid' but drive straight to the town on Iraq's border that was just seized and loaded with weapons to be used by the rebels in the south part of Syria.

To the north the route from Libya to Syria would be closed due to Russian warships and their ability to monitor who is doing what and expose the shipments and where they end up. Hezbollah could get anything from the Russian ships that 'fits their current needs' and that could be convoy info on empty trucks coming out as they would be defended less that when they go in loaded. No next load if a sniper shell takes out the engine block and a new radio link could put Hezbollah in the loop so they don't need eyes 24/7 just to watch a road, what time they will be coming around a certain bend would be helpful. There are also quite a few routes from Lebanon that lead to the high ground within 10km of Damascus. If they can hit Damascus from there then with the right kind of return fire the launch platform can be taken out. Like the truck that carried the men with the TOW munitions using the same stuff that is any recent 'spy movie'. That regular troops can find them in the day in some remote canyon is one method of you don't fave a suitable way of putting an explosion on target as soon as you find them. That would require armed drones from Russia and that might raise eye-brows at this stage. Stopping the incoming missiles should be right at the top of the 'to-do' list.
