 Humvee mishap during airborne operation During an April 11, 2016, airborne operation by the 173rd Airborne Brigade Combat Team, three Humvees slipped from their parachute rigging and plummeted to earth. The Army is investigating what went wrong. 
 
 Someone standing near the camera seems to instantly recognize what is happening, yelling "Ooo, Yeah! Yes!" as it slips. The person in the video laughs as the free-falling Humvee crashes into the ground and kicks up a cloud of smoke. About 30 seconds after the first impact, the second vehicle slips free of its platform and rigging and plummets as well. 
 
 After more laughing, the voice says "called it!" around the time that the third vehicle slips free off camera, which moves to capture the descent and crash. Eventually a person in the group watching notes of one of the crashed vehicles "it's on fire" and asks, "Do we need to call that up?" just before the video ends. 
 
 Pictures purportedly of the carnage in the aftermath, were also posted on Twitter. 
 
 "While (the commanders of the 173rd) are aware of the video, it does not overshadow the hard work of the paratroopers, allies, and partners that took place during Saber Junction 16," Martinez said. 
 
 He said the Army does not know who shot the video nor their role in the exercise: "(Joint Multinational Training Command) is conducting (an investigation) to identify the person who shot the video. As far as disciplinary actions are concerned, nothing has been decided."
