You are correct; https://en.wikipedia.org/wiki/Abdullah_II_of_Jordan#Military_careerIf memory serves me well, I believe at one time The King was in the Jordanian Special Forces.
He may have even been in Command of them as well.
Interesting for sure. Is it SOP to do that with the door at the end? I admit I don't know a safe or easy way to shoot over the car while it is moving... but that seemed like a problem waiting to happen.
