The clip was edited by the propaganda wing of Hamas' military, in an attempt to display advanced intelligence capabilities against Israeli troops.
Hamas has released a series of videos and clips to mark one year since Operation Protective Edge, trying to present the organization's gains made during the war.
The film's authenticity is in doubt however, due to the soldier's long sleeves, as well as the color of the leaves, that seem to indicate that the video was made in the fall, not during the summer operation.
Additionally, IDF protocol orders that all visits near the Gaza border be conducted with full protection including helmets and flak jackets, neither of which is worn by Gantz in the clip.
The officer marked in the video is similar in appearance to the former chief of staff, but his identity is difficult to prove due to the distance of the camera from its subject.
