It completely tears away their claim they destroyed all air defence and the military.

A couple of days before, they were crowing about having total air superiority, that allows them to fly deep into Iranian territory to find targets. A day or two later, the Iranians shot down this plane, and then one of the rescue planes as well.

The Iranians obviously sandbagged them, and waited until they showed up to cause trouble. Oldest trick in the book, and Hegseth fell for it like a fucking Cub Scout.
