A newly released ISIS shows the beheading of a captured Syrian soldier. Then at the end of the video, after some typical Islamic propaganda, the video concludes with what looks like two escaping soldiers being chased after with a tank, or a similar military vehicle. One appears to be run over, the other is shot.
The video was reportedly filmed in Wilāyat al-Khayr, which is what the Islamic State calls the Syrian city of Deir ez-Zor.
Props to Best Gore member @13lunt420media for the video:
