Judging by
this screenshot from the onboard camera of the loitering ammunition Lancet, the 'Gepard' guarding the S-300 was also damaged or eliminated.
There's a video of that hit, you can find it if you're interested, and the Gepard survived the hit. There was no fire and just a small explosion of the drone itself. Most likely fixable, which is why the Russian side only shows that screenshot everywhere. The damage looked like a hand grenade went off on that Gepard's armor.
The "Ivan" operating that drone must be stunned that German tanks don't turn into a flare when hit.
Meanwhile Russians are cooking inside their tanks as they try to escape Ukrainian forces. Notice the half-cooked Invader opening the hatch and escaping his oven at 0:40.
