Footage reportedly shows the Ukrainian 54th Mechanized Brigade doing work to some Russian armor near Marinka, Donetsk Oblast. As shown in the footage provided, Ukrainian forces "walk" rounds onto their target and successfully land a direct hit. Several minutes after sustaining the catastrophic damage, the armored vehicle causes a massive secondary explosion, presumably caused by un-expended ammunition or fuel.

At the time of this writing, it is unclear whether or not the vehicle was abandoned by the Russians. If I had to guess, I would assume it was left behind due to the lack of reaction to contact. Regardless, it is one less vehicle Russian forces can recover.
