Syrian State TV Provides Evidence Of Anti-Aircraft Vehicles Destroyed In The Israeli Airstrike

At the end of the video we see a group of destroyed vehicles, shown in the pictures below

These appear to be the remains of at least three 9K33 Osa/SA-8 Gecko surface-to-air missile systems, with three distinct wheel arches, and the distinct radar area visible in the second picture.  Here's a picture of an undamaged system for comparison

One element that is missing are the missiles from the rear of the vehicle.  These come supplied in the launching tubes, and can be attached individually to the back of the vehicle.  

So what we have is three unarmed surface-to-air missile systems parked next to what the Syrian military has called a "military research centre".  We then have to ask why they were parked there?  It seems by the way they are parked and their lack of missiles they weren't their for defensive purposes, so that remains an open question.
