The turret is clearly visible for about .25 seconds. Try watching the clip fullscreen from 15 to 18 seconds. Even easier to see if you pause playback and then go through it by skipping left and right.
There’s no value in playing the “I see no ships” trick of putting your telescope up to the Z branded eyepatch on this occasion. I’m visually impaired and yet and I can see it clearly. To be fair, it could be a turret from something that’s not a tank, but I don’t think it looks like a T shirt cannon.
There were videos on the Sun website, showing light infantry and BTR. Nothing on your video contradicts it.
To spin it as if it is a force using the station for shield to shell the Uke positions is preposterous.
