The never-before-seen footage, shot by a drone orbiting overhead at the time, shows six ballistic missiles hitting the base.
The CENTCOM, which is the top command overseeing the US military activities in the Middle East, provided the video first to CBS News' "60 Minutes" for a segment that aired this past weekend.
The video starts by identifying five ramps at Al-Assad – named Bravo, Charlie, Foxtrot, Valley, and Voodoo – and the number of aircraft positioned at the time of the attack.
The on-screen notes also indicate that there are usually 10 aircraft on the flight-line and that 51 fixed-wing aircraft and helicopters had evacuated the base ahead of the strikes.
The video then moves on to show two missiles hitting "expeditionary air maintenance facilities," a formal term for "tension-membrane" clamshell-type hangars, on the Bravo ramp. A third missile slams into the Charlie ramp, damaging additional clamshell hangars, as well as offices, living spaces, dining facilities, and latrines.
The fourth missile strikes the Voodoo ramp, hitting more clamshell hangars, as well as a fuel bladder. The last two missiles seen in the footage strike the Charlie and Valley ramps, hitting a rescue operations center, as well as maintenance facilities, a gym, and a dining hall.
