I refer my original post comment... they went crazy due ill discipline.

"Syrian anti-aircraft batteries fired dozens of barrages indiscriminately for 40 minutes after the initial Israeli attack.
In a highly unusual move, the IDF acknowledged the airstrike and released some of the findings of its initial investigation, which concluded that Syrian air defense units fired without aiming and “did not bother to ensure that no Russian planes were in the air.”"
