I suspect it could be a body guard.

Years ago, his dad got in trouble with the Canadians when he was photographed with is coat open and there was a S&W bodyguard on his belt.

He's Star Trek fan too. Did a cameo on Voyager back in '96.

His mother, Princess Muna, was King Hussian's wife. She was Antonette Gardner, daughter of a British Army General. She was a very pretty gal when I was
assigned to her protective detail at WDC. He was a
very young lad at that time.

The King's military career and experience is quite extensive. He flew Apache helicopters and commanded the Jordanian Special Forces. Definitely a lead-from-the-front kind of guy.
