What did Israeli warplanes target at T4 airbase?

The T4 airbase in Homs desert was attacked by the Israeli missiles on the evening of June 2, and according to official information a Syrian force was martyred due to attacks and several others were injured.

In the image published by ImageSat Intl, a small part of the airbase, which is not part of the main infrastructure, is targeted, and it seems likely a important portable equipment.
 
An interesting point is that almost two weeks before the attack, a Syrian IL-76 that returned from Tehran unloaded its cargo exactly near the impact location.
