Hunt for Red October,
If you look at the Las Vegas shooting from the eyes of a Merc or Professional Soldier, this appears to be an assassination attempt on a HVT (High Value Target) incoming on a helicopter to the landing pad on the Mandalay. The MEL( maximum Engagement Line) utilizing both windows covers the incoming approach from the airfield. ( explains the bullet holes in fuel tanks and sqwauk from the tower about shooters on the airfield) It was the direction of fire it the concert. The shooters on the ground are the distraction for local Police, Ground security et al. If it was a ground assault with elevated distraction there would have been armor piercing or RPG etc rounds noted.
The assassination attempt was NOT on a Saud, he set up the target (HVT) that’s why he left the country immediately .
